Powertrain

2017 Acura MDX © Honda Motor Co., Ltd.

2017 Acura MDX © Honda Motor Co., Ltd.

The 2017 MDX is powered by a 3.5-liter direct-injected i-VTEC® 24-valve V-6 engine rated at 290 peak horsepower and 267 lb.-ft. peak torque (both SAE net). The direct injection system precisely places fuel into each combustion chamber for better combustion and greater overall efficiency. The MDX engine also incorporates a range of advanced friction-reducing technologies that help boost fuel efficiency and power output. A crossflow magnesium intake manifold, special “tumble” type intake ports, piston-crown shapes, and an elevated 11.5:1 compression ratio are keys to the MDX’s blend of power and fuel efficiency.

The 2017 MDX with front-wheel drive is rated at 20 mpg city/27 highway/23 combined (with Idle Stop). The 2017 MDX with Super Handling All-Wheel Drive is rated at 19 mpg city/26 highway/22 combined (with Idle Stop). The MDX also meets the stringent ULEV-125 California Air Resources Board (CARB) and EPA Tier 3/BIN 125 emissions standards.

Acura’s i-VTEC® (intelligent Variable Valve Timing and Lift Electronic Control) for the intake valves is combined with Variable Cylinder Management™ (VCM®) in the MDX. VCM varies the working displacement of the engine to match the driving requirements. During startup, aggressive acceleration or when climbing hills — when high power output is required — the engine operates on all six cylinders. During moderate speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders.

The 3.5-liter V-6 is teamed with a Sequential SportShift 9-speed automatic transmission with racing-inspired shift paddles located on the steering wheel. The MDX is available with efficient front wheel drive, or with Acura’s acclaimed Super Handling All-Wheel Drive™ (SH-AWD®) system.

Engine Block and Crankshaft

With its 60-degree V-angle, the MDX’s V-6 engine is inherently smooth and has compact overall dimensions that allow efficient packaging within the vehicle. The V-6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin-casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. The 3.5-liter V-6 uses a high-strength steel crankshaft for minimum weight.

A cooling control spacer positioned in the water jacket surrounding the cylinders helps control warm-up and operating cylinder liner temperatures to reduce friction. Plateau honing of the cylinder lining further reduces friction between the piston skirts and the cylinder walls by creating an ultra-smooth surface. This two-stage machining process uses two grinding processes instead of the more conventional single-stage honing process. Plateau honing also enhances the long-term wear characteristics of the engine.

Pistons/Connecting Rods

Designed with “cavity-shaped” crowns, the MDX engine’s pistons help maintain stable combustion and contribute to stratified-charge combustion. Ion-plated piston rings help reduce friction for greater operating efficiency. Heavy-duty steel connecting rods are forged in one piece and then the crankshaft connecting rods are “crack separated” to create a lighter and stronger rod with an optimally fitted bearing cap.

Cylinder Heads/Valvetrain

Like other Acura V-6 powerplants (with the exception of the NSX), the MDX engine’s 4-valve cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft via an automatically tensioned toothed belt. Made of low-pressure cast, low-porosity aluminum, each cylinder head incorporates a “tumble port” design that improves combustion efficiency by creating a more homogeneous fuel-air mixture. An integrated exhaust manifold cast into each cylinder head reduces parts count, saves weight, improves flow and optimizes the location of the close-coupled catalyst.

i-VTEC with 2-Stage Variable Cylinder Management™ (VCM®)

The MDX SOHC V-6 combines Variable Cylinder Management (VCM) with Variable Valve Timing and Lift Electronic Control (i-VTEC), which changes the lift profile, timing and lift duration of the intake valves. A switching mechanism allows each cylinder to operate with low-rpm valve lift and duration or high-rpm lift and duration. The rear cylinder bank’s valve gear closes all intake and exhaust valves to minimize pumping losses while operating in three-cylinder mode.

The “intelligent” portion of the system is its ability to vary valve operation based on the driving situation and engine rpm. At low rpm, the i-VTEC intake valve timing and lift are optimized (low lift, short duration) for increased torque, which allows a wide range of 3-cylinder operation. As engine rpm builds past 5,350 rpm, the i-VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.

VCM Operation

To help improve the fuel efficiency, Acura’s Variable Cylinder Management (VCM) is used. The VTEC system combines with Active Control engine Mounts (ACM) to allow the VCM system to operate with three cylinders in a wide range of situations to maximize fuel efficiency and lower emissions. When greater power is needed, the system switches seamlessly to 6-cylinder operation.

During startup, aggressive acceleration, or steep ascents — any time high power output is required — the engine operates on all six cylinders. During moderate-speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders.

The VCM system can tailor the working displacement of the engine to match the driving requirements from moment to moment. Since the system automatically closes both the intake and exhaust valves of the cylinders that are not used, pumping losses associated with intake and exhaust are eliminated and fuel efficiency gets a further boost. The system combines maximum performance and maximum fuel efficiency — two characteristics that don’t typically coexist in conventional engines.

VCM deactivates specific cylinders by using the i-VTEC (intelligent Variable Valve-Timing and Lift Electronic Control) system to close the intake and exhaust valves while the Electronic Control Unit (ECU) simultaneously cuts fuel to those cylinders. The spark plugs continue to fire in inactive cylinders to minimize plug temperature loss and prevent fouling induced from incomplete combustion during cylinder re-activation.

The system is electronically controlled, and uses special integrated spool valves in the cylinder heads. Based on commands from the system’s Electronic Control Unit, the spool valves selectively direct oil pressure to the rocker arms for specific cylinders. This oil pressure in turn drives synchronizing pistons that connect and disconnect the rocker arms.

The VCM system monitors throttle position, vehicle speed, engine speed, automatic-transmission gear selection and other factors to determine the correct cylinder activation scheme for the operating conditions. In addition, the system determines whether engine oil pressure is suitable for VCM switching and whether catalytic-converter temperature will remain in the proper range. To further smooth the transition of activating or deactivating cylinders, the system adjusts ignition timing and throttle position and turns the torque converter lock-up on and off. As a result, the transition between 3- and 6-cylinder modes is effectively unnoticeable to the driver.

Drive-by-Wire Throttle System

The MDX’s drive-by-wire throttle system replaces a conventional throttle cable with smart electronics that “connect” the accelerator pedal to a throttle valve inside the throttle-body. The result is less underhood clutter and lower weight, as well as quicker and more accurate throttle actuation. Plus, a specially programmed “gain” rate between the throttle pedal and engine offers improved drivability and optimized engine response to suit specific driving conditions.

Acura’s drive-by-wire throttle system establishes the current driving conditions by monitoring throttle pedal position, throttle valve position, engine speed (rpm) and road speed. This information is used to define the throttle control sensitivity that gives the MDX’s throttle pedal a predictable and responsive feel that meets driver expectations.

There are two different throttle profiles available in the MDX: (1) when the Integrated Dynamics System (IDS) is in the Normal or Comfort setting, the transmission is in “D” (Drive) the drive-by-wire system uses the normal profile; (2) when the Sport mode is selected, the system switches to a more aggressive throttle map to enhance responsiveness.

Direct Injection System

2017 Acura MDX © Honda Motor Co., Ltd.

The MDX’s V-6 engine features a compact, high-pressure direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. A multi-hole injector delivers fuel directly into each cylinder (not to the intake port, as in conventional port fuel injection designs), allowing for more efficient combustion.

The multi-hole injectors can create the ideal stoichiometric fuel/air mixture in the cylinders for good emissions control. Theoretically, a stoichiometric mixture has just enough air to completely burn the available fuel. Based on the operating conditions, the direct-injection system alters its function for best performance. Upon cold engine startup, fuel is injected into the cylinders on the compression stroke. This creates a weak stratified charge effect that improves engine start-up and reduces exhaust emissions before a normal operating temperature is reached.

Once the engine is fully warmed up for maximum power and fuel efficiency, fuel is injected during the intake stroke. This helps create a more homogeneous fuel/air mix in the cylinder that is aided by the high-tumble intake port design. This improves volumetric efficiency, and the cooling effect of the incoming fuel improves anti-knock performance.

Direct Ignition and Detonation/Knock Control

The MDX’s Electronic Control Unit (ECU) monitors engine functions to determine the best ignition spark timing. Two engine block-mounted acoustic detonation/knock sensors “listen” to the engine, and based on this input, the ECU can retard the ignition timing to prevent potentially damaging detonation. The 3.5-liter V-6 has an ignition coil unit for each cylinder that is positioned above each spark plug’s access bore.

Idle-Stop System

To help improve fuel efficiency, the MDX with Advance Package is equipped with Idle-Stop capability. When the system is enabled by the driver and certain operating conditions are met, the Idle-Stop system will automatically shut off the engine when the vehicle comes to a stop. The engine is automatically restarted when the driver releases the brake pedal after a stop.

The system is engineered to operate smoothly and seamlessly. When stopped, a special cold storage evaporator in the air conditioning system helps maintain a comfortable cabin temperature even in warm weather. The MDX ‘s active engine mounts help smooth the restart. Idle-Stop operation is fully integrated into the operation of the MDX ‘s Brake Hold system and its Adaptive Cruise Control (ACC) system.

The Idle-Stop feature can be turned on/off via a button on the center console, located at the near of the electronic gear selector array. The system will automatically turn itself off in certain circumstances, including:

  • If the driver’s seatbelt is not fastened
  • If the engine coolant and/or transmission fluid temperature is too high or low
  • If the vehicle comes to a stop again before vehicle speed reaches 3 mph
  • If the transmission is in a position other than “D”
  • If the battery state of charge is low, or the battery temperature is below 14°F
  • If the climate control system is on and the outside temperature is below -4°F
  • If the rear HVAC fan is set to maximum speed

Close-Coupled Catalysts

The exhaust manifolds of the 3.5-liter V-6 are cast directly into the aluminum cylinder heads to reduce weight, decrease parts count, and create more underhood space. The result of this casting design is that the two primary catalytic converters are positioned much closer to the combustion chambers, enabling extremely rapid converter “light-off” after engine start. A significant weight savings is realized by eliminating traditional exhaust manifolds. Downstream of the close-coupled catalytic converters, a hydroformed 2-into-1 collector pipe carries exhaust gases to a secondary, underfloor catalytic converter.

Emissions Control

The 2017 MDX’s 3.5-liter V-6 engine meets EPA Tier 3/Bin 125 and CARB LEV III ULEV-125 emissions standards and is certified to this level of emissions performance for 150,000 miles. A number of advanced technologies are factors in the emissions performance. The cylinder head-mounted, close-coupled catalytic converters allow for quicker light off after engine start up, and a 32-bit RISC microprocessor within the Electronic Control Unit (ECU) boosts computing power to improve the precision of spark and fuel delivery.

The MDX’s V-6 engine features Programmed Fuel Injection (PGM-FI) that continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical engine operating parameters such as intake air temperature, ambient air pressure, throttle position, intake airflow volume, intake manifold pressure, coolant temperature, exhaust-to-air ratios, as well as the position of the crankshaft and the camshafts.

To further improve emissions compliance, the 3.5-liter V-6 makes use of an after-cat exhaust gas recirculation (EGR) system that allows cleaner, cooler EGR gas to be fed back into the intake system to reduce pumping losses for better fuel efficiency.

Noise & Vibration Control

With its 60-degree V-angle and compact, rigid and lightweight die-cast aluminum cylinder block assembly, the 3.5-liter V-6 powerplant is exceptionally smooth during operation. Other factors that help reduce engine noise and vibration are a rigid forged-steel crankshaft, die-cast accessory mounts, and a stiff cast-aluminum oil pan that reduces cylinder block flex.

Active Control Engine Mounts and Active Sound Control

2017 Acura MDX © Honda Motor Co., Ltd.

A 28-volt Active Control Engine Mount system (ACM) is used to minimize the effects of engine vibration as the VCM system switches between three- and six-cylinder operation. The 28-volt ACM is a key factor in the VCM’s broad range of operation in the MDX. Sensors alert the Electronic Control Unit (ECU) to direct ACM actuators positioned at the front and rear of the engine to cancel engine vibration using a reverse-phase motion. In the cabin of the MDX an Active Sound Control (ASC) system further mitigates low frequencies that can occur during three-cylinder operation.

There are two different Active Sound Control profiles available in the MDX. When the Integrated Dynamics System is in the Normal or Comfort setting, the ASC is tuned for maximum interior quietness. When Sport mode is selected, the ASC allows a more aggressive interior engine sound.

100,000+/- Mile Tune-up Intervals

The 3.5-liter V-6 requires no scheduled maintenance for 100,000+/- miles or more, other than periodic inspections and normal fluid and filter replacements. The first tune-up includes water pump inspection, valve adjustment, replacement of the camshaft timing belt, and the installation of new spark plugs.

Battery Management System

The Battery Management System (BMS) is designed to increase the overall service life of the battery, reduce the chance of a dead battery and help improve fuel efficiency. Should the owner accidentally leave the headlights on or fail to fully close a door causing an interior light to remain on, the BMS will automatically terminate power delivery after a set period of time to prevent the battery from being drained of power. As a result of the discharge protection afforded by the BMS, the battery should always have enough reserve capacity left to start the engine.

The MDX engine makes use of a powerful 130-amp alternator that charges in two different ranges — a low 12-volt range and a high 14-volt range. By controlling the alternator charge voltage range, BMS works to keep the battery in a specific charge range, which can extend the service life of the battery by more than 25 percent. With BMS keeping the battery in a specific charge range, the alternator can run more often in the low range, which generates less drag on the engine resulting in improved fuel efficiency. Application of numerous electrical power reducing items (such as the use of efficient LED lighting and a special humidity control system that has an automatic air conditioning “off” function) allows the BMS to operate the alternator even more frequently in the more efficient low charge mode.

Maintenance Minder™ System

To eliminate unnecessary service stops while ensuring that the vehicle is properly maintained, the MDX has a Maintenance Minder™ system that continually monitors the vehicle’s operating condition. When maintenance is required, the driver is alerted via a message on the Multi-Information Display (MID).

The Maintenance Minder™ system monitors operating conditions such as oil and coolant temperature along with engine speed to determine the proper service intervals. Depending on operating conditions, oil change intervals can be extended to a maximum of 10,000 miles, potentially sparing the owner considerable expense and inconvenience over the life of the vehicle. The owner-resettable system monitors all normal service parts and systems, including oil and filter, tire rotation, air-cleaner, automatic transmission fluid, spark plugs, timing belt, coolant, brake pads and more. To mitigate driver distraction, maintenance alerts are presented on the MID only when the ignition is first turned on, not while driving.

Sequential SportShift 9-Speed Automatic Transmission

All MDX models are equipped with a 9-speed automatic transmission featuring Sequential SportShift. The traditional console-mounted shift lever is replaced with a fully electronic, shift-by-wire gear selector. Park, Neutral and Drive are selected with the push of a button. Reverse is selected by pulling back a dedicated switch. Indicator lights near the buttons indicate the mode selected. As an added safety feature, if the vehicle is brought to a stop in Drive, the system will automatically select Park if the driver’s seatbelt is unbuckled and the driver’s door is opened. A steering wheel-mounted paddle shifter system lets the driver take manual control of transmission gear selection.

Cooperative Transmission Control

Both shift performance and smoothness are improved by cooperative control between the Drive-by-Wire throttle system and the transmissions. The engine is throttled by the engine management system during upshifts and downshifts; thus the function of the engine and transmission can be closely choreographed for faster, smoother shifting. As a result, the peak g-forces (or “shift shock”) are reduced significantly during upshifts and downshifts.

Automatic Modes

The MDX transmission can be operated in two different fully automatic modes that are controlled by the D/S selector button. In Drive (D) mode, the transmission combines fuel efficiency with smooth operation and responsive power when needed. In S mode, more aggressive shift mapping that puts the emphasis on performance-oriented driving, with higher engine rpm for greater acceleration and response.

Smart Transmission Logic

The transmission incorporates an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control — all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for driving conditions, generating excellent performance and smooth operation.

While ascending or descending hills, Grade Logic Control alters the transmission’s shift schedule to reduce shift frequency and improve speed control. The transmission ECU continually measures throttle position, vehicle speed and acceleration/deceleration to determine when the vehicle is on a hill. The shift schedule is then adjusted — during ascents to hold the transmission in lower gears to boost climbing power, and during descents to provide greater engine braking.

Shift Hold Control keeps the transmission in its current (lower) gear ratio during aggressive driving, as in the case of decelerating at a corner entry. Shift Hold Control leaves the chassis undisturbed by eliminating excess shifting and ensures that power will be immediately available (without a downshift) at the corner exit. Cornering G Shift Control monitors the vehicle lateral acceleration to determine when the MDX is turning. When the system detects sufficient cornering speed, it will suppress any unwanted upshifts. This prevents the transmission from upshifting during a corner, which could upset the chassis balance thus requiring downshifting again at the corner exit when the throttle is applied.

Paddle Shifter Operation in Drive and Mode

While in Drive mode, special transmission logic programming allows the use of the steering-wheel-mounted paddle shifters. When the driver operates the paddle shifters, the transmission responds to the driver’s shift command and then returns to its normal fully automatic mode if further paddle shift inputs are not made within a given time. This special logic makes it easy for the driver to command a quick downshift without leaving the convenience of Drive mode.

Paddle Shifter Operation in Drive S Mode

When the transmission is set to Drive S mode, a pull on the racing-inspired paddle shifters (mounted on the steering wheel) places the transmission in fully manual mode until another mode of operation is selected. A digital display in the instrument cluster indicates the selected gear.

A double-kick-down feature lets the driver command a sport-minded double downshift — such as from fifth to third gear. By pulling on the left downshift paddle twice in rapid succession, the transmission will drop directly to the chosen lower gear ratio. The drive-by-wire throttle system also creates a “blip” of the throttle to help match gear speeds while downshifting.

To prevent harm to the powertrain when the transmission is paddle shifted by the driver (including during double-kick-down shifts), the system will inhibit potentially damaging shifts. As an added safety measure, the Electronic Control Unit (ECU) can also cut off fuel to the engine to prevent over-revving. If fuel cut-off is insufficient to prevent engine over-revving, as may be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine.

Front Wheel Drive

The MDX offers standard front wheel drive. With its efficient design and light weight, the MDX front wheel drive system makes a significant contribution to overall fuel efficiency. With EPA fuel economy ratings of 20/27/23 (city/highway/combined), the front-wheel drive MDX with Idle Stop has a 1-mpg advantage over its SH-AWD counterpart in the city, on the highway, and in the combined ratings.

Super-Handling All-Wheel Drive (SH-AWD)

The MDX is available with Acura’s acclaimed Super Handling All-Wheel Drive (SH-AWD), which progressively distributes optimum torque not only between the front and rear axles, but also between the left and right rear wheels. The system is complemented by Agile Handling Assist which employs the anti-lock brake system to individually brake either the left or right front wheel to reduce yaw delay (the period between the steering wheel input and the rotation of the body) to improve corner traceability and balance.

The benefits of the SH-AWD® system are superior all-weather handling and neutral, accurate steering under power that is unmatched by front-drive, rear-drive or conventional all-wheel-drive systems.

By rotating the outside rear wheel faster than the front axle while cornering, SH-AWD uses torque vectoring to create a yaw moment to help turn the vehicle through the corner — reducing understeer and improving controllability. With cornering forces more evenly distributed between front and rear tires, overall cornering power is increased — on wet or dry roads.

Vehicles with high power ratings using conventional front or rear drive systems often employ a limited-slip differential to help maintain traction when under power. By linking inside and outside drive wheels, these systems tend to resist turning and can increase understeer. Conventional AWD systems similarly work to link the inboard and outboard tires as well as the front and rear axles—which can create resistance to turning. Using torque vectoring to help turn the vehicle, SH-AWD® delivers more responsive, neutral and predictable handling performance, while providing outstanding all-weather traction and control.

Electronic Controls and Parameters

The SH-AWD system works in cooperation with the MDX’s Vehicle Stability Assist™ (VSA®) system and Agile Handling Assist to optimize torque distribution for superior handling and traction utilization. The Electronic Control Unit (ECU) provides information on engine rpm, airflow and transmission gear-ratio selection, while the VSA ECU provides wheel-speed data. The SH-AWD ECU also monitors steering angle, lateral G-forces, vehicle yaw rate and electromagnetic clutch engagement for the right and left rear axle shafts. Drive torque is calculated from ECU information, and then the acceleration situation, wheel spin, lateral G-force and steering angle are used to determine the front-to-rear torque distribution and the torque split between right and left rear wheels.

SH-AWD® operating parameters include:

  • Up to 90-percent of available torque can be transferred to the front wheels during normal cruising
  • In hard cornering and under acceleration, up to 70-percent of available torque can be directed to the rear wheels to enhance vehicle dynamics
  • Up to 100-percent of the torque sent to the rear axle can be applied to either the left or right rear wheel, depending on conditions

SH-AWD System Layout

The MDX SH-AWD® is a full-time all-wheel-drive system that requires no driver interaction or monitoring, thanks to a torque-transfer unit that is bolted directly to the front-mounted transaxle. The torque-transfer unit receives torque from a helical gear that is attached to the front differential’s ring gear, and a short horizontal shaft and hypoid gear set within the torque-transfer unit’s case send power to the rear propeller shaft, which in turn transfers power to the rear drive unit.

The MDX’s lightweight SH-AWD rear drive unit is constantly overdriven by 2.7-percent. The resulting overdrive effect is regulated by hydraulically-operated left and right-side clutch packs located in the rear drive unit that independently control the power delivered to each rear wheel. Up to 1200 N-m of torque can be delivered to either rear wheel, providing torque vectoring capability that is effective in corners with a radius of as little as 49.2 feet while also providing a limited-slip differential function when needed.

The hydraulically operated clutches can be controlled as a pair to alter front/rear torque split or they can be controlled independently to allow 100 percent of available rear axle torque to go to just one rear wheel, which gives the system the unique ability to yaw the MDX into turns for superior handling.

In this iteration of SH-AWD, an electric motor powers a pair of hydraulic pumps – on for each clutch pack. A pair of linear solenoids controlled by the Electronic Control Unit (ECU) selectively sends pressure to the clutch packs, which in turn control the amount of power sent to each rear wheel.

Trailer Hitch and Trailer Hitch ATF Cooler Kit (Optional)

A dealer-installed receiver-style trailer hitch accommodates a variety of trailer coupler designs, and includes a draw bar, retaining pin, clip, and wiring harness with 7-pin round-style connector. Trailer hitch balls of 1-7/8 -inch or 2-inch are available separately. MDX SH-AWD models have a 5,000 lb. tow rating, when equipped with the optional Trailer Hitch ATF Cooler Kit.

Remote Engine Start with Vehicle Feedback

The MDX with Technology Package and above provides the ability to start the vehicle’s engine remotely. This enables drivers to start their MDX, thereby activating the climate control system before they get to the vehicle — perfect for hot or cold days. The remote is designed to have a range of operation of at least 300 feet. To start the engine remotely, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. When the engine is started remotely, the wipers, lighting and audio systems remain off, and the security system remains set. The engine will run for up to 10 minutes after remote starting, and then shut off automatically if the owner doesn’t reach the vehicle within that time. When the owner does get to the MDX within 10 minutes, the engine will keep running while the owner unlocks the vehicle and gets in.

This system also provides feedback to the owner to confirm whether the engine is running or the vehicle is locked. The remote has three LED indicators: amber, green and red. To confirm engine start, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. The amber indicator will flash while the remote communicates with the vehicle. If the engine is running, the green LED will then light for one second. If the engine is not running, the red indicator will light for one second. To verify whether the vehicle is locked, the owner presses the LOCK button once. After the amber light comes on, either the green or red LED will light for one second to indicate that the vehicle is locked or not, respectively. And if the red LED flashes three times, the vehicle is out of the remote’s range. This system can provide owners with the comfort of a pre-warmed vehicle on a cold winter morning — or a pre-cooled interior on hot days. Plus, it adds the convenience and confidence of knowing that their vehicle is securely locked, even far beyond the range of a typical remote.

Thanks to its use of advanced materials including aluminum, high-strength steel and magnesium, the 2017 MDX’s restyled body combines exceptional rigidity with low vehicle mass. This combination provides the foundation for the MDX’s confident handling capabilities, refined ride quality, and its particularly high mitigation of cabin noise, vibration and harshness (NVH). High structural rigidity at crucial suspension mounting points allows the MDX’s suspension systems to be tuned to provide the best combination of ride and handling.

Collision performance is further enhanced by Acura’s next-generation Advanced Compatibility Engineering™ (ACE™) front frame structure and the MDX’s one-piece stiffener ring — made of ultra-high strength steel. It comprises the A-pillar and B-pillar, roof rail and lower frame member — for improved management of collision energy in frontal offset and side impacts and roof load management in the event of a rollover.

Next-Generation Advanced Compatibility Engineering (ACE) Body Structure

The MDX’s Advanced Compatibility Engineering (ACE) body structure is an exclusive body design that enhances occupant protection and crash compatibility in frontal crashes. It uses a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle, helping to reduce the forces transferred to the passenger compartment. It can help to more evenly disperse the forces transferred to other vehicles in a crash as well. ACE also helps reduce the chances that one vehicle will override another, improving crash compatibility of vehicles that differ in size. ACE goes further by offering additional strength and protection in small overlap frontal collisions, which are among the most severe.

Acoustic Glass

The MDX utilizes 4.5-mm thick, 3-layer acoustic windshield and 4.8 mm front door glass to help mitigate wind, road and traffic noise in the cabin.

Underbody Airflow

Carefully managing underbody airflow helps reduce turbulence and drag for improved fuel efficiency, while also enhancing stability at highway speeds. Strategically placed aerodynamic underbody components — including front splash shields, an engine exit cover, and a mid-floor undercover — help smooth airflow between the body and road surface, while also helping to minimize power-robbing turbulence and drag. A front air dam with a broad wickerbill, along with strakes positioned ahead of the rear tires, further improves efficient airflow. These techniques help maximize fuel efficiency, increase stability and reduce wind noise on the highway.

Advanced Materials, Lower Weight

High-strength steel, aluminum and magnesium total 65 percent of the MDX body structure. The MDX has the lightest published weight in its segment which directly contributes to its powerful acceleration, light and nimble handling, and class-leading fuel economy ratings.

The MDX is assembled from steel stampings that are robotically welded together to form a single, lightweight unit-body with a high level of rigidity. A variety of advanced materials and techniques give this structure exceptional strength and uniformity. One is high-strength steel, which composes 59 percent of the body structure by weight, including the use of 1,500-megapascal ultra-high strength “hot-stamped” steel in 7 percent of the body, enhancing collision protection while minimizing vehicle weight.

An example of high-strength components in the MDX are the one-piece stiffener rings around the front doors. Formed from a single piece of hot-stamped steel, each ring provides immense strength for enhanced performance in frontal and side impacts, as well as enhanced roof crush protection. Likewise, the rigid tailgate opening is engineered to distribute loads through the rear suspension mounts, further aiding body stiffness.

The MDX steering hanger beam is made of a magnesium casting, which spans the entire width of the interior (inside of the instrument panel). This 3-piece component saves 7.5 pounds compared to an aluminum hangar beam, while also reducing the potential for intrusion of the steering column into the cabin in a frontal collision.

Noise, Vibration and Harshness (NVH) Mitigation

To create a premium driving experience, extensive research and countermeasures were applied to help reduce noise, vibration and harshness (NVH) throughout the MDX. Acura engineers began by working to eliminate NVH at its source with technologies such as a highly rigid unibody tightly controlled manufacturing tolerances, a highly rigid aluminum-alloy engine block and forged-steel crankshaft, electronically calibrated engine mounts, careful aerodynamic tailoring, acoustic glass, and more.

Road Noise Reduction

To help isolate road noise and reduce its intrusion into the cabin, the lower suspension components attach to fully isolated steel subframes that ride on specially tuned bushings. In addition, improved door sealing and melt sheet (an asphalt-based sound-damping material) is bonded to the floor and wheel arches of all Acura vehicles at the time of assembly.

Wind Noise Reduction

Smoothing airflow over the complex shape of a vehicle body can help reduce not only aerodynamic drag, but also the wind noise that is transmitted to the cabin. The MDX was tested extensively in a full-sized wind tunnel. Wind-tunnel testing combined with sophisticated computer modeling allowed engineers to identify areas of the body that are prone to wind noise — and then analyze fine detail changes with a high degree of accuracy.

One result of this testing is the MDX’s body-panel fit, which helps minimize gaps that create turbulence and wind noise when the vehicle is traveling at speed. Other details include carefully styled A-pillars and side mirrors, a flush-fitting windshield, moonroof and side glass, and numerous other design details that all contribute to the low wind-noise characteristics of the 2017 MDX.

Wind-noise attenuation details also include components that are not visible. For instance, the MDX’s body sections are isolated using 22 clip-in foam inserts that expand during the baking cycles of the body painting process. This material reduces wind noise transmitted into the vehicle. The fin-type 2.7-inch high antenna used for AM/FM and SiriusXM® radio, AcuraLink and engine remote start, is positioned at the rear of the roof panel and is designed for low wind noise at speed.

Active Control Engine Mounts

The MDX has an Active Control Engine Mount system (ACM) that minimizes the effects of engine vibration as the Variable Cylinder Management (VCM) system switches between 3- and 6-cylinder modes. Special vibration sensors alert the Electronic Control Unit (ECU) to direct ACM actuators — which are positioned at the front and rear of the engine — to cancel vibration. Additionally, an Active Sound Control system, operating through the vehicle’s stereo speakers, further reduces low-frequencies associated with 3-cylinder operation by producing a reverse-phase sound profile.

Four-Wheel Independent Suspension

The MDX’s independent front and rear suspension systems are engineered to provide long wheel travel and excellent compliance for a luxurious ride, together with the precise damping and spring rates needed for excellent handling and a sporty driving feel.

Front Suspension

In front is a strut-type system with forged-aluminum lower control arms with hydraulic bushings, coil springs and a solid stabilizer bar. This setup uses moderate spring rates, relatively firm damping and specially tuned bushings for a smooth, controlled ride with exceptional cornering abilities. The upper front damper mounts provide a “triple path” load-bearing system that helps absorb road vibration and harshness.

Rear Suspension

At the rear is a compact multi-link design with a tubular stabilizer bar. This multi-link system allows a generous amount of wheel travel and excellent compliance for a supple ride, together with confident cornering and handling. All rear suspension control arms are steel — including high-strength steel upper and lower control arms. The MDX’s rear suspension design allows for a low floor, providing easier third-row ingress and egress.

Amplitude Reactive Dampers

Amplitude Reactive Dampers provide superior ride comfort and handling in all driving conditions. The dampers have two separate hydraulic circuits — one tuned to optimize the ride quality on smooth roads with relatively small irregularities, and the other tuned to handle large inputs resulting from rough roads or large steering and braking inputs. As a result, the MDX remains smooth and supple when cruising, and secure and tight feeling in corners with reduced body roll.

The key Amplitude Reactive Damper technology consists of two separate damping pistons: a main piston and a second piston. To improve overall ride comfort, when smaller inputs occur during normal driving conditions, only the main piston works to provide the ideal damping characteristics. To improve the MDX’s ride and handling on rougher surfaces and during more aggressive driving, the second piston operates to provide additional damping force.

The Amplitude Reactive Dampers are a purely mechanical system that does not require electronic controls. Altogether, they provide a much wider range of effective damping performance than offered by the previous base MDX.

Vibration-Damping Subframes

The MDX’s engine, transmission and suspension components are mounted on rigid steel subframes. These subframes attach to the unit body at rubber-isolated mounting points that help keep powertrain and road noise, vibration and harshness (NVH) out of the passenger cabin. The subframe rear mounts are filled with specially tuned hydraulic fluid for maximum effectiveness. Permanently sealed, they require no scheduled maintenance. The rear subframe is particularly sophisticated, with hydroformed side elements for maximum strength and minimal weight.

Motion-Adaptive Electric Power Steering

The MDX’s Motion-Adaptive Electric Power Steering (EPS) system helps enhance fuel efficiency by putting less demand on the engine, compared to engine-driven hydraulic-boost systems. At low speeds, EPS lowers steering effort, improving driver comfort and convenience in city driving and while maneuvering. The system also provides a precision road feel while cornering, along with a firmer and sportier feel on the highway.

The MDX’s standard Integrated Dynamics System (IDS) adjusts steering effort depending on the selected mode — Normal, Comfort or Sport. In Normal mode, the steering effort is balanced between comfortable and sporty. Selecting the Comfort mode eases steering effort for a more relaxed driving experience, especially at low speeds. The Sport mode provides a firmer steering feel with higher effort that complements more aggressive driving.

Motion-Adaptive EPS works with Vehicle Stability Assist (VSA®) and Electric Power Steering to detect instability in low traction conditions (both during cornering and under braking) and automatically initiates steering inputs aimed at prompting the driver to steer in the correct direction. This technology supports the driver’s action in operating the vehicle more safely and comfortably.

The Motion-Adaptive EPS system consists of a rack-and-pinion steering gear with an electric motor located next to the pinion axle. To control the level of assist the Powertrain Control Module receives signals from a speed sensor and, coupled with a steering sensor for torque and rotation, calculates the optimal amount of assist and sends a signal to the electric motor.

When compared to the operation of a conventional hydraulic-pump power steering system, Motion-Adaptive EPS increases efficiency because it does not draw a continuous amount of power directly from the engine. Other advantages of electric power-assisted steering include its simplicity, its lower power consumption (which helps improve fuel efficiency), and its compactness (and resulting lower overall weight).

Agile Handling Assist

Standard on all MDX trims, Agile Handling Assist selectively uses the vehicle’s brakes to improve initial turning response and overall cornering ability. Agile Handling Assist utilizes brake vectoring to improve corner traceability and confident handling feel. By applying braking force to the inside wheels during cornering at high lateral G, the system creates a yaw moment, thus generating more turning force and reducing understeer.

Four-Wheel Disc Braking System with Electronic Brake Distribution

The MDX has 4-wheel disc brakes with a 4-channel anti-lock braking system (ABS) for a powerful and linear brake feel, and confident stops in a wide range of driving conditions. The ventilated front discs are 12.6 inches in diameter and use two-piston calipers, while the solid rear discs are 13.0 inches in diameter and have single-piston calipers. The calipers are designed to reduce brake drag when not in use, reducing rolling resistance and improving fuel efficiency in the process.

ABS with Brake Assist

An Anti-lock Braking System (ABS) independently modulates braking power at each wheel to help the driver retain steering control during heavy braking, while Brake Assist recognizes hard or emergency braking situations and almost instantly applies full braking force when appropriate.

Electric Parking Brake

Included in all MDX trims for 2017, the Electric Parking Brake (EPB) makes using the parking brake easier and more comfortable, promoting its use by drivers. Actuating the parking brake is now as simple as pushing a switch on the center console. To release the parking brake, the driver simply puts the car in gear and presses on the accelerator pedal. In addition to being simpler and more convenient to use than a traditional parking brake, the new Electric Parking Brake makes hill starts easier when the MDX is parked on a grade. As with a traditional manually activated parking brake, EPB functions on the rear wheels only.

Trailer Stability Assist

Standard on SH-AWD models, Trailer Stability Assist helps enhance vehicle stability while a trailer is being towed. An integral part of Vehicle Stability Assist (VSA), Trailer Stability Assist detects trailer oscillations that can result from improper loading, excessive speed, adverse road conditions, crosswinds or emergency-avoidance maneuvers.

When such oscillations are detected, Trailer Stability Assist provides a warning and gives the driver the opportunity to reduce speed. If the driver does not reduce speed — or does not reduce speed sufficiently to stabilize the vehicle — then VSA automatically activates to help damp the oscillations before they can increase and further upset the stability of the vehicle and trailer.

Aluminum Alloy Wheels

2017 Acura MDX © Honda Motor Co., Ltd.

2017 Acura MDX © Honda Motor Co., Ltd.

The range of available wheels on the 2017 MDX has been improved to include standard 18- and available 20-inch sizes, an upgrade from the 2016 MDX’s standard 18- and available 19-inch wheel sizes.

Base MDX models (FWD and SH-AWD) have stylish 5-spoke 18-inch aluminum-alloy wheels, with a machine finish. Included with the Technology Package is 10-spoke, 20-inch aluminum-alloy wheels with a machine finish, while the Advance and Entertainment Package 20-inch wheels have a 5-spoke design and machine finish. In addition, 20-inch aluminum-alloy wheels are available as an accessory for the base MDX.

High-Performance All-Season Tires

Base MDX models (FWD and SH-AWD) have 245/60 R18 105H high-performance all-season tires, while the MDX with Technology and Advance Packages have lower-profile 245/50 R20 102H high-performance all-season tires for enhanced driving performance. All tires offer precise steering feel, high levels of grip in all-season driving conditions, and low rolling resistance for greater fuel efficiency.

For MDX SH-AWD models only, a T165/80D17 temporary spare tire on a 17×4.0-inch steel wheel is mounted below the trunk, where it does not intrude on interior storage space. All MDX FWD models receive a tire sealant and inflator kit in lieu of a spare wheel and tire.

Off-Road Capability

Engineers took thorough measures to develop the 2017 MDX with useful off-road capabilities, including testing in snow, mud and sand. The available computer-controlled SH-AWD system helps the MDX meet typical off-road challenges without the need for low-range gears. The system is designed for “decision free” operation, meaning that the driver does not need to actively choose when to engage all-wheel-drive. The system is always active and ready to distribute torque as needed.

Ground clearance and approach, breakover and departure angles are configured for typical SUV driving conditions including dirt and gravel roads, mud and snow. These specifications mirror those on the 2014 to 2016 MDX.

Aggressive, Aerodynamic Styling

The revised bodylines and the addition of contrasting brightwork inject a new level of sporty attitude and elegance into the MDX equation, enhancing the presence of Acura’s flagship SUV in the luxury ranks. The new grille and more rakish fender lines, hood lines and headlights evoke greater strength, while the hood incorporates shapes and crush areas for improved pedestrian safety. Below the front fascia are aggressive air intakes together with recessed mounts for the available LED fog lights.

Bright detailing on the lower sills contrast with the upper body, adding new strength and balance to the MDX profile. While a new rear bumper fascia design features a black lower and body-color upper areas, lightening the overall look, while the new through-bumper dual exhausts and a new skid garnish emphasize performance.

Dual Exhaust Outlets

In another upgrade for the 2017 MDX, stylized dual exhaust outlets with bright finishers exit through the black rear lower fascia for a premium, sporty appearance.

One-Touch Power Moonroof with Tilt Feature

The MDX has a one-touch power moonroof with tilt feature that will fully open or close with a single touch of the switch. The moonroof mechanism was purposely designed to provide ample headroom. The moonroof has a sliding sunshade that opens with the roof and can be closed to block sunlight. To tilt or slide the moonroof, the driver or front passenger needs only to fully press the ceiling-mounted switch once (instead of pressing and holding it for several seconds). The moonroof fully opens or closes automatically. However, if the operator wishes to only partially open or close the moonroof (such as to achieve partial ventilation), a lighter touch yields fully manual control. The moonroof can also tilt to provide ventilation. An auto-reverse feature is built in, helping to ensure that the moonroof will not forcefully close if someone’s hand or arm is positioned in the path of the glass. If an obstruction is detected, the mechanism will reopen the moonroof.

LED Lighting

The 2017 MDX incorporates a wide range of available light-emitting diode (LED) exterior lighting features, including LED Daytime Running Lights (DRL), LED Jewel Eye™ headlights, LED side marker lights and LED taillights. LED side mirror-mounted turn signals are standard on all models, and LED fog lights are offered on Advance grades.

LED Daytime Running Lights (DRL)

The MDX has bright, distinctive LED Daytime Running Lights (DRL). A signature design feature of the new MDX, the DRLs utilize a wing shape positioned above and beside the LED headlights. Shaped to match the rugged, purposeful stance of the new MDX, the LED DRL array is wider at the side and thinner on top, gradually tapering as it moves toward the inside of the headlight lens. Stylistically, the DRLs strongly and clearly define the front corners of the MDX.

LED Jewel Eye™ Headlights with Auto On/Off

The 2017 MDX’s LED Jewel Eye™ headlights provide improved nighttime illumination and visibility compared to contemporary high-intensity discharge (HID) headlights. The low beams reach approximately 460 feet compared to approximately 360 feet for traditional halogen low beams, and the beam width is approximately 100 feet compared to approximately 65 feet for halogen low beams.

Besides improving driver confidence and active safety, the LED headlights use less energy, helping to enhance fuel efficiency by reducing engine loads. In addition, the LED headlights last up to three times longer than HID headlights and up to six times longer than halogen headlights — contributing to less frequent replacement and the associated cost savings. An auto on/off function is included, and the low-beams are also keyed to the remote key fob operation.

Auto High Beams

The 2017 MDX new auto high beam (HSS) feature uses a camera located on the rearview mirror mount to continually scan for oncoming traffic. Included on the MDX Technology Package and Advance Package, the system illuminates the high beams except when oncoming or proceeding traffic is detected and then automatically switches to the LED low-beams. Requiring no intervention or action from the driver, the auto high beam feature significantly improves nighttime illumination for enhanced active safety.

There are numerous advantages to the auto high beam system, including earlier driver detection of objects in the roadway during nighttime driving. Earlier detection of objects can lead to and a reduction in stopping distances which in turn results in a higher level of driver confidence.

The system functions when the headlight switch is in the Auto position, and may be disabled and reactivated by a quick pull on the high-beam stalk. An HSS icon appears on the instrument panel when the system is functioning. The auto high beam feature automatically disengages during rainy conditions, when low beam lighting is preferable. Four consecutive wipes of the windshield wiper deactivate the system. Auto high beam then automatically reactivates when the rain ceases.

Fog Lights

The MDX Advance Package is equipped with LED fog lights to enhance visibility in inclement weather. Inspired by the Acura NSX, a special mesh feature surrounds the fog lights for a premium and sporty appearance.

LED Taillights

Outside Mirrors with Reverse Gear Tilt-Down

To improve convenience while parallel parking, the MDX’s aerodynamically sculpted outside mirrors have a reverse-gear tilt-down feature that allows the driver to see the curb or curbside objects. Either the left- or right-hand mirror can be selected to automatically tilt down when reversing. After shifting into reverse, the driver simply moves the mirror-adjustment selector switch position to either the right or left. The corresponding mirror then tilts down to provide a clear view of the curb or curbside on that side of the vehicle. The mirror automatically returns to its previous position when the gear-selector lever is moved out of Reverse.

A power-folding feature on the Technology and Advance Packages allows the outside mirrors to be folded against the body sides when the vehicle is parked, reducing the chance of damage to the mirror housing in tight parking areas. The power-folding feature can be activated by pressing a switch on the driver’s door armrest when the transmission is in Park or Neutral and the ignition switch is in the Accessory or On mode.

Included in the Advance and Entertainment Packages, auto-dimming side mirrors use the same activation sensor as the MDX’s auto-dimming inside rearview mirror. The auto-dimming function of all three mirrors helps reduce glare during nighttime driving, especially from the headlights of following vehicles.

Included in the Technology and Advance Packages, LED puddle lights, mounted on the bottom of the outside mirror housings, add convenience for the driver and front passenger at night. These LEDs automatically illuminate when the driver approaches and the vehicle detects the remote.

Rain-Sensing Wipers

MDX models with the Technology and Advance Packages include rain-sensing wipers that automatically activate if water is detected on the windshield. Designed to cover the maximum possible windshield area on all trims, the left (driver) and right (front passenger) windshield wipers are 26 and 20 inches long, respectively. The rear wiper is 14 inches long.

One-Touch Turn Signals

The MDX’s one-touch turn signals improve convenience for the driver when making routine lane changes. With this system, a quick movement of the turn-signal lever (between 0.4 sec. and 1 sec.) provides three blinks of the turn signals — an ideal strategy for changing lanes.

Low-Profile Roof Rails

Included with the Advance Package, aerodynamically shaped roof rails add versatility without detracting from the MDX’s streamlined package. Chrome-plated for an upscale appearance, the rails accept available cross bars that can hold a variety of accessories including a storage case or racks for bikes, boards or skis.

Smart Entry with Push Button Start

The MDX features Acura’s Smart Entry with Push Button Start. The Smart Entry system permits access to the vehicle’s front doors without having to operate the key fob or a conventional key (all four doors are accessible with the Technology Package and up). The Smart Entry remote has a unique digital identity and the MDX can be unlocked when the driver grabs one of the door handles while the remote is in his/her possession. When carrying the fob (or if all doors are unlocked), the tailgate can be opened using the handle located on the MDX’s rear tailgate.

Once the driver has opened the door and is seated, the Smart Entry system allows the MDX to be started by pushing the Engine Start/Stop button positioned on the instrument panel (so long as the driver’s foot is on the brake); to turn off the MDX, the driver simply pushes the button again with the vehicle in Park. When leaving the vehicle, a press of the soft-touch button on the exterior front door handles or tailgate locks all the doors. Alternatively, pressing the Lock button on the Smart Entry remote will also simultaneously lock all doors.

Smart Entry also features a unique “quick vent” feature. When the operator depressed the “unlock” button on the keyless remote for two seconds after unlocking the doors, the system lowers all four side windows and opens the power moonroof to quickly vent interior heat. In addition, by inserting the built-in key into the driver’s door lock and holding the key in the “lock” position, all open windows can be simultaneously raised.

Remote Preferences

The Acura MDX comes with two keyless remotes that can be set with a unique preference to accommodate the preferences of two different drivers. The available preferences include driver seat, steering wheel and mirror positions, along with select HVAC functions. Other preferences include turning entry lights on or off, audio system pre-sets, air conditioning preferences, and navigation system settings. In the event both owners use the car at the same time, the MDX will recognize the keyless remote that approaches the driver door first.

Tailgate Functions

Like previous MDX models, the 2017 MDX’s rear tailgate can be controlled from the remote key fob — including unlocking, opening and closing the tailgate. In addition, the rear tailgate is part of the Smart Entry system. When the MDX is locked, and the driver approaches the rear tailgate, the tailgate will automatically unlock (as long as the fob comes within about 32 inches of the vehicle). The tailgate can then be opened simply by lightly touching the switch membrane beneath the Acura badge.

Capless Fueling System

A first for MDX, capless fueling eliminates the fuel cap, meaning that fueling the vehicle simply requires opening the fuel lid, refueling, and then closing the lid. This smart and easy-to-use design eliminates the need to touch a dirty fuel cap, reduces the possibility of damaging the vehicle’s paint with the fuel cap or tether, or forgetting the fuel cap at the gas station. It also eliminates the possibility of activating an emissions warning by failing to properly re-install the fuel cap. The fuel door unlocks with a remote button release inside the vehicle.

Exterior Colors

The MDX is available in seven exterior colors, including two metallic and five pearl colors. New colors for the 2017 model year are Modern Steel Metallic and the Acura exclusive Black Copper Pearl.

All colors are expressive and luxurious to compliment the redesigned MDX’s sophisticated and dynamic body shape. The acid-resistant epoxy clear-coat paint is superior to typical clear-coat paints for increased resistance to urban pollutants.

The 2017 MDX exterior colors include:

  • Lunar Silver Metallic
  • Modern Steel Metallic
  • Black Copper Pearl
  • Crystal Black Pearl
  • Dark Cherry Red Pearl
  • Obsidian Blue Pearl
  • White Diamond Pearl

Interior

2017 Acura MDX © Honda Motor Co., Ltd.

2017 Acura MDX © Honda Motor Co., Ltd.

The 2017 MDX offers a high level of luxury, convenience and technology in a spacious cabin that’s ideal for kids or clients. High-end appointments including new available genuine wood accent trim elevates the MDX’s luxury ambience. With the MDX’s long wheelbase and compact rear suspension design, smart interior packaging provides usable and versatile passenger and cargo space, and exceptionally easy third-row access. Available with seating for seven, or with an all-new 6-passenger configuration with luxurious second-row captain’s chairs, the MDX interior offers welcoming comfort in every seating position.

The One-Touch Walk-In feature for the third-row seats, along with a wide foot entry point and low step-in height, makes third-row ingress and egress simple. The Extended Slide feature for the second-row seats provides 5.9 inches of total fore-aft seat travel, providing great flexibility in accommodating the needs of both second- and third-row passengers. Up front, the center console features a large storage area that can accommodate a medium sized purse and even a couple of tablet computers — something few competitors can match.

Interior Styling

The MDX interior builds on Acura’s premium luxury design themes, with clean high-end detailing, intuitive functionality and elegant lines. An Acura design concept called “dual personal structure” guided development of the MDX. It divides the front cabin space into areas centered on the driver and front passenger, with a center stack and console that is easily accessible to each person. Fit and finish have received close attention throughout the interior, with high-quality, soft-touch materials and available perforated Milano leather with stain resistant technology. For the first time ever, the MDX with the Advance Package offers the warm luxury of genuine wood interior accents.

Versatile, Spacious Cabin

The MDX has always been appreciated for its roomy and versatile cabin and user-friendly design. With three rows of seating, the MDX can accommodate up to seven passengers (six passengers for Advance grades with second-row captain’s chairs). Usability is a key element of the MDX’s interior design, as evidenced by the clever One-Touch Walk-In feature that makes third row access easy, even for many children. When it comes to cargo carrying utility, the MDX seating can be quickly reconfigured to accommodate a blend of passengers and cargo. With the second and third row seating folded flat, the MDX can offer up to 90.9 cubic feet of cargo space.

Driver-Oriented Cockpit

The strategy behind the MDX’s interior design, based on Acura’s “the Synergy between Man and Machine” product direction, is to put the driver’s needs first and foremost, to help the driver focus on operating the vehicle in an intuitive and natural way. All important systems and controls are within easy reach, and the systems used most frequently — audio, cruise control, Bluetooth® HandsFreeLink®, available satellite-linked Acura Navigation System with Voice Recognition™ and Multi-Information Display — have controls conveniently positioned on the steering wheel. Typical of Acura interior design, the soft-touch switchgear of the MDX is engineered to deliver a high-quality feel and positive action. The main instrumentation is an easy-to-read analog design, supplemented with digital and graphic displays.

Standard Leather Seating Surfaces

The MDX seats feature luxurious leather seating surfaces, with upgraded perforated Milano leather with contrasting piping and stitching in the MDX with Advance and Entertainment Packages.

Transmission Controls

All MDX models feature an advanced Electronic Gear Selector that replaces a traditional gear lever with an intuitive and easy-to-operate push-button array. The interface frees up center-console space while presenting an advanced and futuristic appearance.

Advanced and Intuitive Instrumentation and Controls

The MDX has sophisticated analog instrumentation with large tachometer and speedometer flanking a color Multi-Information Display (MID) that provides a range of information and trip computer functions. The tachometer and speedometer are flanked by analog coolant temperature and fuel level gauges.

Audio/Information Screen

2017 Acura MDX © Honda Motor Co., Ltd.

2017 Acura MDX © Honda Motor Co., Ltd.

All MDX models feature a bright, full-color 8-inch audio/information screen positioned high in the center stack of the instrument panel. Its high placement puts it close to the driver’s line of sight where it’s easy to see. Besides audio system information, the screen also offers backup camera views and access to a range of customizable features.

On-Demand Multi-Use Display™

The impressive range of technology offered in the MDX presented designers with the challenge of balancing capability with simplicity. The solution was a 7-inch On Demand Multi-Use Display™ (ODMD) touch screen positioned within easy reach of the driver and front passenger. The touchscreen controls a wide range of features, and with its contextual menus, it displays relevant items while minimizing clutter. To make it easy to use, the screen offers audible and vibratory touch feedback — both can be adjusted or shut off based on the owner’s preference. Customizable shortcuts allow the MDX driver to set easy-to-access presets for Places, Phone, Climate and Audio functional categories.

Genuine Wood Interior Accents

For the first time, the MDX offers genuine wood interior accents as standard equipment with the Advance Package. Two types of wood are used, based on the interior color. Olive Ash Burl wood is sourced from Europe and has a rich, dark tone. Black Limba wood from West Africa has a lighter, warmer tone. Both varieties have a low-gloss satin finish to better display the character of the wood. The wood accents are positioned on the instrument panel, front doors and center console.

Power Windows, Locks and Mirrors

Power windows are standard equipment on all MDX models and include auto-up and -down operation on the driver’s and front passenger’s windows. Power door locks, Smart Entry and heated power exterior mirrors are also standard equipment. Power folding exterior mirrors are standard in the Technology and Advance packages.

Auto-Dimming Rearview Mirror

2017 Acura MDX © Honda Motor Co., Ltd.

2017 Acura MDX © Honda Motor Co., Ltd.

All MDX models feature an electro chromatic interior rearview mirror that automatically dims during nighttime driving to reduce glare from the headlights of following vehicles.

Versatile Cargo Area

Dual large brushed aluminum plates measuring 16.2 inches long by four inches wide help protect the carpeted cargo-area floor during loading and unloading. With both second- and third-row seats folded, the cargo floor is near fully flat with only a slight, 4.5-degree pitch.

Even with the third-row seat in the upright position, the storage area is designed to accommodate bulky items, including a golf bag, stroller, two suitcases or a 56-quart cooler. Four rectangular satin-finished tie-down anchors allow securing cargo when the third-row seat is folded.

Lifting the cargo floor panel reveals an additional hidden storage area with a cargo volume of 1.8 cu. ft. — enough to hold folding chairs (bag type) or two laptop computer cases. In addition, a handy storage bin is positioned at the left side of the cargo area behind the rear seat, with a 12-volt power outlet nearby. Two incandescent bulbs evenly illuminate the storage area.

The third-row seats are split 50/50, and each side can be folded flat with one pull of a handle. The head restraints fold forward first, and then the seatback is unlocked so it can be folded forward easily.

Interior Lighting

The MDX’s analog instruments are backlit with LED lighting and feature high-contrast markings, and the look of a premium chronograph. The gauge package progressively illuminates to give the driver a welcoming feel upon entry. When the door is first opened, the instrument lighting comes to life and then brightens progressively to 100-percent illumination when the ignition is switched on. The illuminated instrument panels then come alive, indicating that the MDX is ready to go. At the end of the drive, the instrument lighting dims progressively.

The interior switches are illuminated to make them easy to locate at night, including the switches on all four doors and the steering wheel. In addition to front and rear overhead interior lights and map lights, the MDX also has a complement of low-level LED interior cabin lights. Ambient lighting in the ceiling illuminates the front center console, and the front foot wells and door handles. Entry front foot well lighting welcomes the passenger as they open the doors. The MDX interior lights feature “theater dimming,” which can be set by the driver to one of several dimming rates via the Multi-Information Display.

Storage Features

The MDX interior offers a range of convenient storage features for the driver and passengers. All four doors offer storage bins and bottle holders, and there are cupholders on each side of the third row of seating.

An integrated HVAC assembly frees up space for an exceptionally large center console storage space. It’s large enough to accommodate a moderately sized purse, a tablet computer and more. The console also features two beverage holders, a front pocket with a 12-volt outlet, a cell phone/iPod® pocket next to another 12-volt power outlet and USB Audio Interface, a sliding tray over the main storage space and another tray under the sliding, padded armrest.

Engine Immobilizer

Complementing the remote entry system is a standard engine-immobilizer system. A special electronically coded key prevents the vehicle from being started — even if a mechanical duplicate of the key is used. A transponder, built into the key, signals the immobilizer control unit that the key is genuine. If the vehicle is hotwired, or an unauthorized key is used, the engine will not start.

Comfort and Convenience

  • Hill Start Assist
  • Walk Away Door Lock

Smart Entry and Push Button Start/Stop

All 2017 MDX models offer the upscale convenience of Smart Entry and Push Button Start/Stop.

Smart Entry

The Smart Entry system simplifies approaching, entering and operating the MDX — especially when the driver has his or her hands full. To gain entry to vehicle, the driver simply pulls one of the two front door handles while the remote is in his or her possession.

Push Button Start/Stop

Once the driver has opened the door and is seated, the driver simply pushes the START/STOP button positioned on the instrument panel while pressing the brake pedal to start the vehicle. Powertrain operation and certain electrical functions are ended when the START/STOP button is pressed again at the conclusion of the drive. For accessory mode the driver simply presses the START/STOP button without pressing the brake pedal.

Remote Engine Start

The MDX with the Technology Packages and above provides the ability to start the vehicle’s engine remotely. This enables drivers to start their MDX, thereby activating the climate control system before they get to the vehicle — perfect for hot or cold days. The remote is designed to have a range of operation of at least 300 feet. To start the engine remotely, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. When the engine is started remotely, the wipers, lighting and audio systems remain off, and the security system remains set. The engine will run for up to 10 minutes after remote starting, and then shut off automatically if the owner doesn’t reach the vehicle within that time. When the owner does get to the MDX within 10 minutes, the engine will keep running while the owner unlocks the vehicle and gets in. The default 10 minute time limit can be extended an additional 10 minutes, if desired.

This system also provides feedback to the owner to confirm whether the engine is running or the vehicle is locked. The remote has three LED indicators: amber, green and red. To confirm engine start, the owner presses the LOCK button and then holds the ENGINE button for a few seconds. The amber indicator will flash while the remote communicates with the vehicle. If the engine is running, the green LED will then light for one second. If the engine is not running, the red indicator will light for one second. To verify whether the vehicle is locked, the owner presses the LOCK button once. After the amber light comes on, either the green or red LED will light for one second to indicate that the vehicle is locked or not, respectively. And if the red LED flashes three times, the vehicle is out of the remote’s range.

This system can provide owners with the comfort of a pre-warmed vehicle on a cold winter morning — or a pre-cooled interior on hot days. Plus, it adds the convenience and confidence of knowing that their vehicle is securely locked, even far beyond the range of a typical remote.

Locking

After parking, a press of the LOCK button on the remote will simultaneously lock all the doors and tailgate. A touch of the soft-touch lock button on either front door handle locks all doors and tailgate to secure the MDX. The system will not allow the remote to be locked in the interior of the MDX.

Walk Away Door Lock

The new Walk Away Door Lock feature automatically locks the MDX when the driver leaves the vehicle. This hands-free locking capability adds everyday convenience that’s especially useful when the driver has his or her hands full or is distracted. In typical use, when all doors are closed and the driver walks away, the MDX will automatically lock when the key holder’s distance from the vehicle exceeds 6.5 feet for two seconds or more and when no other key is detected inside the vehicle. An audible buzzer sounds and the hazard lights flash to confirm that the vehicle has locked. The Walk Away Door Lock feature is programmable, and may be turned on or off as the driver prefers.

Leather-Wrapped Steering Wheel

The leather-wrapped steering wheel features euro-style stitching and incorporates the most commonly used controls, allowing the driver to keep their hands on the wheel. Phone and audio controls are on the left side; cruise control and multi-info display controls are on the right side, along with the switches for Lane Keeping Assist System (LKAS) and Adaptive Cruise Control with Low-Speed Follow. Tucked out of view but within fingertip reach is a pair of paddle shifters that allow for manual operation of the Sequential SportShift 9-speed automatic transmission.

Heated Steering Wheel

The MDX with Advance Package offers the comfort of a standard heated steering wheel. A heating switch mounted on the lower left side of the steering wheel can be activated when the ignition is switched on, and is also integrated to the Remote Engine Start System for automated heating when appropriate. Acura Genuine Accessories also offers an optional heated steering wheel for other MDX models.

Power Front Bucket Seats

Considering the luxury mission and performance of the MDX, its seating required extensive engineering development. The front bucket seats are designed to provide comfortable support for a wide range of body types, along with secure lateral support for cornering. The MDX driver’s seat features 10-way power adjustability (8-way power seat plus 2-way power lumbar support). The front passenger seat offers 8-way power adjustability standard, with 10-way power adjustability available on the MDX with Advance and Entertainment Packages. All driver’s seat power adjustments are included in the Smart Entry system (among many other features). The system stores a pair of user profiles regarding seat settings — one for each of the two key fobs that come standard with the MDX.

Heated front seats are standard in the MDX. An algorithmically controlled ECU allows for three temperature settings, along with fast warm-up and smooth, precise temperature control. The Advance and Entertainment Packages include ventilated front seats.

Second-Row Seats with Extended Slide

The MDX’s roomy second-row seating is designed for maximum comfort and versatility, with a 60/40 split-folding design that makes it easy to accommodate passengers or long cargo. The second-row seats also have an Extended Slide feature that provides a total of 5.9 inches of fore-aft seat travel (3.9 inches forward, 2 inches rear), offering passengers great flexibility in selecting the optimal balance of second- and third-row legroom. A nearly flat floor opens up foot room for a center passenger. Five-position reclining second-row seatbacks further aid comfort for second- and third-row passengers. There is also a padded, folding center armrest with two cupholders. In the MDX with the Technology and Entertainment Package trim and above, second-row seat heaters are standard.

Second-Row Captain’s Chairs

The MDX with Advance Package offers the comfort and luxury of standard second-row Captain’s Chairs. Roomy and supportive, the captain’s chairs offer all-day comfort and upscale luxury. The second-row center console positioned between the captain’s chairs offers convenient utility, and features a pair of additional USB ports inside the console for the second row and two additional ports on the rear of the console for the third row. Like the standard second-row seats, the second-row captain’s chairs slide fore-and-aft, recline and offer One-Touch Walk-In access for the third row.

Third-Row Seats with One-Touch Walk-In Access

The MDX’s compact rear suspension, long wheelbase and One-Touch Walk-In feature provide easy access to the third row. Even young kids will find it easy to gain access to the MDX’s third-row seats from either side of the vehicle via the illuminated One-Touch Walk-In buttons — one button located outboard on the base of the second-row seats and a second button on the upper portion of the second-row seatback. With a single push of the electronically actuated button, the second-row seatback (left or right) folds forward and the seat automatically slides forward. To help reduce the risk of unintentional operation, the buttons will not operate unless the brake pedal is depressed or the gear selector is in Park.

HomeLink® Remote System

All MDX models feature a HomeLink® universal remote system, located in the overhead control panel, which works with nearly all garage door openers and gates systems, and an ever growing list of other radio frequency (RF)-controlled devices.

Driver Preferences

All MDX models come with two keyless remotes with unique identifiers. Each remote can be set with unique profiles to accommodate the individual preferences of two different drivers. The available preferences include driver seat and mirror positions, along with select HVAC functions. Other preferences include turning entry lights on or off, audio system pre-sets, air conditioning preferences, and navigation system settings. In the event both owners use the vehicle at the same time, the MDX will recognize the keyless remote that approaches the driver’s door first.

Capless Fueling System

The MDX ‘s new capless fueling eliminates the traditional fuel cap, meaning that fueling the vehicle simply requires opening the fuel lid, refueling, and then closing the lid. This smart and easy-to-use design eliminates the need to touch a dirty fuel cap, reduces the possibility of damaging the vehicle’s paint with the fuel cap or tether, or forgetting the fuel cap at the gas station. It also eliminates the possibility of activating an emissions warning by failing to properly reinstall the fuel cap.

The system consists of two integrated components, an outer shutter mechanism that prevents the intrusion of dirt and dust, and a self-sealing fueling flap that is closed by a torsion spring. Both operate automatically.

At a gas station, the driver simply opens the fuel lid and then inserts the fuel nozzle. Inserting the nozzle automatically opens the outer shutter and fueling flap. When fueling is complete, removing the fuel nozzle automatically closes both the fueling flap and outer shutter.

Hill Start Assist

The Hill Start Assist function helps to prevent the vehicle from rolling backwards when the driver switches from the brake pedal to the accelerator pedal while the vehicle is stopped on a hill. Hill Start Assist automatically activates when the vehicle senses a certain incline and is fully stopped in any forward gear when facing up hill or reverse gear when facing downhill. The system uses a longitudinal G-sensor along with a wheel speed sensor to control the hydraulic brake modulator. Hill Start Assist, when activated, will release the brakes when the driver depresses the throttle or if the driver doesn’t press the accelerator after a few seconds.

Auto High-Beam System

The MDX ‘s auto high-beam system, standard in the Advance Package, makes optimal use of the vehicle’s headlights. When the headlight switch is set in the Auto position, the system automatically illuminates the high beams until an integrated camera detects oncoming or proceeding traffic and automatically switches to low beams.

Multi-Angle Rearview Camera

A multi-angle rearview camera is standard on the MDX. It offers three viewing angles (wide view, normal view and top view). Drivers may select the preferred view according to driving conditions. The rearview image is displayed on the 8-inch color audio/information display. On-screen guidelines help the driver better judge distances, and predictive guidelines help make maneuvering in reverse easier.

Surround-View Camera System

In the MDX with Advance Package, four exterior cameras provide a 360 view of the space immediately around the vehicle through the navigation display. A camera button among the nav display controls or an even more conveniently located button on the end of the turn signal lever changes camera views.

When Reverse is selected, the rear camera view appears on screen along with an overhead 360 view. Guidelines appear in each view, which correspond with the angle of the front wheels angle to show the vehicle’s predicted rearward path. A press of either camera button switches to show the rear view alone, and another press shows a wide-angle rear view.

Pressing either “Camera” button (when not in reverse) shows the 360 view combined with a front view that is ideal for putting the vehicle in the ideal position in the garage. Another button press provides a front wide-angle view that is useful for helping spot an approaching vehicle or person when nosing out a tight spot with a blocked side view. Additional views include looking ahead from both sides and just the passenger side view alone.

One-Touch Power Moonroof with Tilt Feature

The MDX features a power tilting and sliding front moonroof with a manual sunshade. To tilt or slide the moonroof, the driver or front passenger needs only to fully press the ceiling-mounted switch once (instead of pressing and holding it for several seconds). The moonroof fully opens or closes automatically. However, if the operator wishes to only partially open or close the moonroof (such as to achieve partial ventilation), a lighter touch yields fully manual control. The moonroof can also tilt to provide ventilation. An auto-reverse feature is built in, helping to mitigate the possibility of a pinched finger or limb. If the moonroof motor’s ECU detects a threshold level of mechanical resistance, indicating a possible obstruction, the motor will automatically reverse and reopen the moonroof.

Tri-Zone Automatic Climate Control – GPS-Linked with Technology and Advance pkgs.
All MDX models feature a tri-zone automatic climate control system that lets the driver, front passenger and rear passengers set temperatures to their individual liking. Technology and Advance packages add a GPS-link for still better control of individual settings.

To operate the HVAC system, easy-to-read buttons and controls are positioned within easy reach. The HVAC system can also be controlled by voice command (MDX with Technology Package and higher grades), and additional custom settings can be accessed through the 7-inch On-Demand Multi-Use Display™.

With its position-sensing ability, the GPS navigation system (MDX with Technology Package and higher) contributes to overall passenger comfort with a 3D solar sensing feature. Based on continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and front passenger. Combining this information with input from a solar sensor located on top of the instrument panel, the climate control system automatically adjusts cooling/heating and airflow from side to side as needed to compensate for asymmetrical solar heating. Further, on the Advance and Entertainment Packages, the heated and ventilated front seats are electronically linked to the climate control system, expediting the transition to the desired temperature.

Rear Sunshades

For increased rear-seat privacy, reduced solar loading and glare, the MDX (with Technology and Entertainment Packages and up) has manually operated sunshades for each rear door side window.
