Ford Shelby GT350 Mustang
One of the most iconic performance Mustang nameplates of all time has returned, the all-new Shelby® GT350 Mustang.
The original Shelby GT350 introduced in 1965 established the Mustang’s performance credentials. The all-new Shelby GT350 Mustang, featuring the most powerful naturally aspirated Ford production engine ever, is a world-class performance vehicle, designed to tackle the planet’s most challenging roads – an all-day track car that’s also street legal.
The new GT350 builds on Carroll Shelby’s original idea – transforming a great every-day car into a dominant road racer – by taking advantage of a dramatically improved sixth-generation Mustang to create a truly special driving experience. Driving enthusiasts behind the wheel of a Shelby GT350 can expect to be treated to the most balanced, nimble and exhilarating production Mustang yet.
Ford engineers took an innovative approach with GT350. Rather than develop individual systems to perform well independently, every component and shape is optimized to work in concert; balance is the key. While paying rigorous attention to detail, the team pushed the envelope with cutting-edge materials and technologies.
“When we started working on this car, we wanted to build the best possible Mustang for the places we most love to drive – challenging back roads with a variety of corners and elevation changes, and the track on weekends,” said Raj Nair, Ford group vice president, Global Product Development.
“Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant – nimble, precise handling, and massive stopping power.”
Track-tuned driveline
Early in the development of the GT350, it was decided that a high-revving, naturally aspirated V8 engine would best suit a track-focused Mustang.
“The final product is essentially an all-new powerplant unique to GT350 – “and one that takes true advantage of the new chassis dynamics of the Mustang platform,” said Jamal Hameedi, chief engineer, Ford Global Performance Vehicles.
The new 5.2-liter V8 engine is the first-ever production V8 from Ford with a flat-plane crankshaft, an architecture typically found only in racing applications or exotic European sports cars. Unlike a traditional V8, where the connecting rods are attached to the crankshaft at 90-degree intervals, this design evenly spaces all crank pins at 180-degrees intervals.
The 180-degree, flat-plane layout permits a cylinder firing order that alternates between cylinder banks, reducing the overlap of exhaust pressure pulses. When combined with cylinder-head and valvetrain advancements, this permits better cylinder breathing, further extending the performance envelope of the V8.
The result is the most powerful naturally aspirated production Ford engine ever, at 526 horsepower, with a torque peak of 429 lb.-ft. The track capability is enhanced by the output characteristics of the engine – the 5.2-liter V8 features an exceptionally broad torque curve. Combined with its high-revving ability, the flat-plane 5.2-liter V8 gives drivers an enormous amount of performance and flexibility within each gear of the lightweight six-speed manual transmission. A standard Ford-tuned Torsen limited-slip differential optimizes cornering grip and straight-line traction.
“Make no mistake, this is an American interpretation of a flat-plane crankshaft V8, and the 5.2-liter produces a distinctive, throaty howl from its four exhaust tips,” Hameedi said.
Balanced dynamics
The new Mustang platform is the strongest in the history of the brand, with torsional stiffness increased 28 percent over the previous model. That stiff structure ensures the suspension geometry remains consistent, even under hard driving on back roads and tracks. Front stiffness is further improved on GT350 with a cutting-edge injection-molded carbon fiber composite grille opening and optional lightweight tower-to-tower brace. The front track has been increased while spring rates and bushings have been recalibrated all around, with ride height reduced compared to Mustang GT.
For optimum handling, the wheels need to respond quickly to the contours of the road and driver inputs. Reducing unsprung mass is key to improving that response, but a balance must be struck between taking mass out of a suspension and delivering truly capable braking performance. Due to the significant speeds the car can develop, the GT350 features the most track-credible brake system ever offered on a Ford vehicle in terms of absolute stopping power, fade resistance and brake pedal feel. The brakes are two-piece cross-drilled iron brake discs mounted to aluminum hats. At the front are massive 394-millimeter rotors clamped by Brembo six-piston fixed calipers with integrated caliper bridges while 380-millimeter rotors at the rear utilize four-piston calipers.
GT350 makes use of extra-stiff 19-inch aluminum alloy wheels – 10.5 inches wide in front, 11.0 inches in the rear – clad in state-of-the-art Michelin Pilot Super Sport tires with GT350-specific sidewall construction, tread face and compound. The custom tires are designed to deliver maximum grip on the road or during weekend track days.
Ultra-quick responsiveness to changing conditions is provided by the first-ever Ford application of continuously controlled MagneRide dampers. The dampers are filled with a hydraulic fluid impregnated with iron particles; when an electric current is passed through the fluid, a near instant adjustment of the suspension performance can be made. With wheel position sensors monitoring motion thousands of times per second combined with other vehicle data, changes can be made to each corner independently every 10 milliseconds for optimum handling performance. This is a system designed not just to make the car handle better, but to instill greater confidence in even the best driver.
Obsession to detail
“Everything we changed on GT350 is purely functional-driven design, with the goal of improving the overall performance of the car,” said Chris Svensson, Ford design director, The Americas. “We optimized the aero shape of the car, and then fine-tuned what was left to increase downforce and cooling airflow.”
All bodywork from the windshield forward is unique to this high-performance model, and up to two inches lower than Mustang GT.
The new aluminum hood has been lowered and sloped, compared to the base Mustang, tightly wrapped around the engine for the smallest possible aerodynamic signature. Front and rear aero elements have been balanced to work together on the track. The fascia has been resculpted to provide the aggressive lower front splitter with maximum pressure and a ducted belly pan delivers significant downforce. The hood outlet acts as a heat extractor while also reducing underhood lift at high speed. At the rear, much of the engineering was focused on creating an aggressive functional diffuser doing double duty to increase downforce and provide cooling air to the optional differential cooler, and a subtle lip spoiler across the trailing edge of the decklid increases downforce without adding excess drag.
The athletic stance of the all-new Mustang is further accentuated with recontoured aluminum front fenders to accommodate the wider front track and wider wheel arches. Front fender vents work with vented inner fenders to draw out turbulent air in the wheel wells and smoothly direct it down the side of the car. The forward-angled grille is designed with individual openings to draw air through the radiator, high-pressure engine air intake, cooling ducts for the front brakes, and optional with the Track Pack an engine oil cooler and a transmission cooler.
Shelby GT350 has been weight-optimized to balance capability with on-track durability. Lightweight components are engineered to offset added extreme-performance hardware, and, as a result, the standard GT350 tips the scales at 3,760 pounds while the GT350 Track Package weighs in at 3,791 pounds.
Focus-driven cockpit changes
Like everything else about GT350, the interior has been optimized for driving, beginning with the specially designed Recaro sport seats with a unique cloth. Hundreds of hours and many prototypes went into a seat that is both comfortable in daily driving and capable on the track. A flat-bottom steering wheel makes it easier for the driver to get in and out and more ergonomic on the racetrack. Gauges are upgraded to reflect the enormous performance capability of the car. Chrome and bright finishes have been reduced or eliminated to prevent any sun glare that may distract the driver.
The advanced technology inherent to Mustang has been deployed for duty in the Shelby GT350. An all-new integrated driver control system allows selection of five unique modes that tailor ABS, stability control, traction control, steering effort, throttle mapping, MagneRide tuning and exhaust settings depending on driver preference to achieve maximum performance. Drivers are invited to test them all.
Drivers interested in comfort, convenience and entertainment upgrades may select the Tech Pack, which includes power leather-trimmed seats, Shaker Audio, 8-inch SYNC® with MyFord Touch LCD touch screen, and dual zone electronic temperature control to name a few features.
“We took the best Ford Mustang yet and massaged every aspect of the car that affects the performance driving experience,” said Hameedi. “We tested endlessly on the most challenging roads and tracks in the world, and we believe serious drivers will love the Shelby GT350 Mustang.”
Shelby GT350 Mustang is the latest in an all-new line of Mustangs including Mustang EcoBoost, Mustang GT, and the specially designed 50th Anniversary Edition Mustang.
Ford Shelby GT350R Mustang
Ford Shelby® GT350R Mustang is the latest track-ready masterpiece to emerge from the Ford Performance mantra of “innovation through performance.”
In 1965, Ford and Carroll Shelby developed a road-racing version of the popular Ford Mustang – the Shelby GT350 Competition model. Lighter, more powerful, and with a highly developed suspension, it is one of the most iconic racing Mustangs ever produced.
Arriving in the fall, the new Shelby GT350R has been designed and engineered in the same spirit, delivering never-before-seen track capability from a Mustang – thanks to innovations in aerodynamics, chassis engineering and light-weighting.
“The Shelby GT350R Mustang is a no-compromise car in the pursuit of maximum track capability,” said Raj Nair, Ford group vice president, Global Product Development. “It is a thoroughbred street car making use of technology and ingenuity to deliver performance few enthusiasts have ever experienced.”
Shelby GT350R features the first-ever production V8 from Ford with a flat-plane crankshaft – the most powerful naturally aspirated engine Ford has ever produced – plus a specially tuned suspension. It is fitted with revised spring rates and antiroll bars, lower ride height, unique track-tuned alignment settings, revised bushings and jounce bumpers, cross-axis ball joints in the front suspension, and revised calibration controlling the MagneRide dampers.
“The Shelby GT350R Mustang is a car with the nimbleness and power delivery you want on a road course,” said Nair. “This isn’t just about horsepower. The Shelby GT350R is an all-around balanced athlete – one that is extraordinarily precise and agile.”
Track technology for the street
Shelby GT350R features standard lightweight carbon fiber wheels, making Ford the first major automaker to introduce this innovative wheel technology.
Carbon fiber wheels have been offered on only a handful of exotic supercars and will benefit Shelby GT350R performance by shaving critical unsprung weight. The 19×11-inch front and 19×11.5-inch rear wheels weigh approximately 18 pounds each and provide 16 pounds of unsprung weight reduction per wheel compared to an equivalent aluminum wheel. Handling and acceleration performance see serious benefits. The wheels also provide a reduction in rotational inertia of more than 40 percent, which positively impacts acceleration and braking performance.
The lightweight wheels will be shod in Michelin’s top-shelf Pilot Sport Cup 2 high-performance tires with rubber compound and a construction unique to the Shelby GT350R. This combination of incredibly stiff and light wheels with bespoke tires offers customers exceptional steering feel and levels of performance.
Weight reduction in pursuit of performance
Shelby GT350R engineers delivered against aggressive targets for weight reduction. If a part did not make the car faster around a road course, it was considered for deletion.
Items removed include air conditioning, the stereo system, rear seats, trunk floorboard and carpet, backup camera and emergency tire sealer and inflator. Exhaust resonators also have been removed for weight savings with the benefit of creating a sharper exhaust tone.
Shelby GT350R is more than 120 pounds lighter than the Shelby GT350 Track Pack model, which has proven its durability in multiple 24-hour racetrack tests.
For customers seeking more comfort in their Shelby GT350R, Ford is offering an optional Electronics Package. Included is dual-zone air conditioning, 8-inch touch screen with navigation, seven-speaker audio system, turn signal mirrors and more.
Aggressive aerodynamics
Shelby GT350R has been optimized for aerodynamic excellence. Details including the hood vent for heat extraction and lift reduction, underbody belly pans front and rear, an aggressive diffuser, vented wheel wells and turbulence-reducing fender vents, wheel air curtains and side skirts all remain on Shelby GT350R, but the car’s downforce capability has been increased.
Revisions to the front splitter maximize downforce, while an all-new high-efficiency carbon fiber rear wing has been added in anticipation of competition. The wing moves the vehicle’s center of pressure rearward while improving downforce and lift balance – ideal for high-speed track work.
“Shelby GT350R’s highly efficient aerodynamics, innovative light-weighting and world-class chassis deliver a truly spectacular driving experience that makes you feel like a professional racing driver,” said Kerry Baldori, Ford Performance chief functional engineer.
World-class powertrain
The new 5.2-liter dual-overhead-cam V8 engine is the first-ever production V8 from Ford with a flat-plane crankshaft – an architecture typically found only in racing applications or exotic European sports cars.
Unlike traditional V8s, where the connecting rods are attached to the crankshaft at 90-degree intervals, this design evenly spaces all crank pins at 180-degree intervals to optimize high-speed engine breathing. It is the most powerful naturally aspirated production Ford engine ever, with 526 horsepower and 429 lb.-ft. of torque.
An air-to-oil engine oil cooler typically only found on race cars maintains engine temperatures under the most severe conditions, as does a standard cooler for the six-speed manual transmission.
A Ford-tuned limited-slip Torsen differential with 3.73 axle ratio is optimized for cornering grip and straight-line traction, while an electronically moderated rear-mounted air-to-oil differential cooler maintains ideal temperatures during track driving.
Dedicated R design details
Aside from carbon fiber wheels, larger front splitter and rear wing, Shelby GT350R includes distinct design details. Exterior touches include red painted brake calipers, red pin striping at the edges of the optional over-the-top racing stripes and Shelby GT350R badging. Inside is high-contrast red stitching, Shelby GT350R badging and the D-shaped steering wheel fitted with a red center mark at the top.
New breed of performance
The limited-production Shelby GT350R will be available in the United States and Canada in the fall of 2015, and is one of more than 12 new Ford Performance vehicles coming by 2020.
“This is the pinnacle of performance Mustangs today,” said Dave Pericak, director, Ford Performance. “The Shelby GT350R Mustang lays the groundwork for a story that will play out for years to come on the track and the street.”
Performance
526-Horsepower Ford Shelby GT350 Mustang Exceeds 100 Horsepower Per Liter with New 5.2-Liter Flat-Plane V8
The all-new Ford 5.2-liter flat-plane crankshaft V8 will produce 526 horsepower and 429 lb.-ft. of torque in Shelby GT350 Mustang and Shelby GT350R Mustang – an engine unique to the two models set to go on sale this fall.
“The Shelby GT350 program began with a clear objective – create the most balanced, nimble and exhilarating production Mustang yet,” said Jamal Hameedi, Ford Performance chief engineer.
“Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant. The high-revving, naturally aspirated 5.2-liter flat-plane V8 delivers on every target we set – high horsepower, broad torque curve, aggressive throttle response and light weight.”
The all-new 5.2-liter V8 is not only Ford’s most powerful naturally aspirated engine ever, but also its most efficient in terms of specific output. Without turbocharging or supercharging, the flat-plane crankshaft V8 produces 102 horsepower per liter of displacement. The new engine is also the highest-revving V8 in Ford history – with a redline of 8,250 rpm.
Unlike traditional V8 engines, the all-new 5.2-liter uses a flat-plane crankshaft more typically found in a Ferrari sports car or in racing applications. The design of this new engine for the Shelby GT350 was optimized using computer-aided engineering and fully digital performance simulations. Millions of intake, cam and exhaust configurations were iterated before arriving at the optimal combination.
Better engine breathing delivers optimal power
Traditional cross-plane crankshaft V8 engines attach the piston-carrying connecting rods to the crankshaft at 90-degree intervals, creating a “cross” of counterweights when viewed down the axis of the crankshaft. In the all-new Ford 5.2-liter V8, the connecting rods attach to the flat-plane crankshaft at aligned 180-degree intervals – creating what looks like a flat line of counterweights when viewed down the axis of the crankshaft.
Beyond a change in the characteristic sound of an American V8, the flat-plane crankshaft helps improve cylinder exhaust-pulse separation by allowing a firing order that alternates ignition events between the V8’s two cylinder banks. This can vastly improve engine breathing, and subsequently allow the engine to make more power.
The result in the new 5.2-liter V8 – in addition to a uniquely exotic, delicious engine note – is 526 horsepower at 7,500 rpm and 429 lb.-ft. of torque at 4,750 rpm. Even more impressive is the track-tuned flexibility of the engine’s exceptionally wide powerband. It produces 90 percent of peak torque from approximately 3,450 rpm through 7,000 rpm, and features a racetrack-friendly spread of nearly 3,000 rpm between its torque and horsepower peaks.
In both Shelby GT350 and Shelby GT350R, the all-new 5.2-liter will be paired with a six-speed manual transmission as its only gearbox option. The Tremec TR-3160 six-speed manual is specifically engineered for less mass and high-rpm application in the new Shelby Mustangs. The six-speed features a lightweight, die-cast aluminum case and clutch housing for increased overall powertrain stiffness. Gear cross-sections, the dual-mass flywheel and dual-disc clutch are all optimized for an overall reduction in inertia and weight.
Other aspects of the new 5.2-liter V8 (actual displacement is 5,163 cubic centimeters) include a slightly oversquare bore and stroke of 94×93 millimeters, and a performance-enhancing 12.0:1 compression ratio. Computer numerical control-machined cylinder heads house camshafts that develop a massive 14 millimeters of lift for both the hollow-stem intake valves and sodium-filled exhaust valves. A single, fast-acting 87-millimeter throttle body – the largest ever used for a Ford engine – feeds air to the engine, allowing for a simpler, lighter intake.
Further reducing engine weight is a unique new aluminum engine block featuring Ford’s patented plasma transferred wire arc cylinder-liner technology. This process eliminates typical heavy iron cylinder liners with a deposition process. The forged-steel flat-plane crankshaft is “gun drilled” to reduce total engine weight and to improve bay-to-bay cylinder breathing. A lightweight, high-capacity composite oil pan contains baffling designed for sustained high-speed cornering and hard braking.
“A new Mustang as exceptional as the Shelby GT350 deserves an equally extraordinary engine,” said Dave Pericak, director, Ford Performance.
“The all-new naturally aspirated 5.2-liter V8 perfectly fits the balanced dynamics of the Shelby GT350, and we believe this new engine will become a performance legend.”
Innovative engineering
Ford Shelby GT350 Mustang Raises the Bar for Handling
The all-new Ford Shelby GT350 builds on Carroll Shelby’s original idea – transform Mustang from a great everyday car into a dominant road racer, elevating it to a new level.
Shelby GT350 raises the bar significantly over the already very capable 2015 Mustang GT performance pack, combining the best technologies and most thoroughly engineered components to create the most athletic Mustang ever built.
“When we started working on this car, we wanted to build the best possible Mustang for the places we most love to drive – challenging back roads with a variety of corners and elevation changes, and at the track on weekends,” said Raj Nair, Ford group vice president, Global Product Development. “Every change we made to this car was driven by the functional requirements of a powerful, responsive powerplant – nimble, precise handling and massive stopping power.”
Suspension tuned for maximum performance on road and track
Handling is the performance playground of Shelby GT350, and the car’s suspension is heavily revised to maximize cornering performance.
Shelby Mustang features all-new aluminum front knuckle, hub and bearing assemblies that are stiffer and lighter than the standard parts. Rigid bushings are fitted to the control arms and subframes for improved steering feedback. Heavy-duty bearings are added for increased lateral stiffness. Front and rear antiroll bars are increased in diameter for improved body control. In an example of obsession to detail, one side of the rear suspension features a new counter-wound rear spring and matching rear control arm so the left and right sides are mirror images – perfecting wheel motion.
MagneRide suspension makes first appearance for Mustang
The star of the Shelby GT350 suspension is the first-ever Ford application of continuously variable MagneRide dampers. The dampers are filled with a hydraulic fluid impregnated with iron particles. When an electric current is passed through the fluid, near-instantaneous adjustment of the suspension performance can be made. With wheel position sensors monitoring motion thousands of times per second combined with other vehicle data, changes can be made to each corner every 7 milliseconds for optimum handling performance.
Tireless calibration and tuning has resulted in an integrated driver control software which monitors wheel position, steering angle, damper temperature, signal quality, vehicle position and much more. This advanced software rides on top of the car’s drive modes and provides a degree of suspension performance never before seen in a production Mustang. This system is not just designed to make the car handle better, but to instill greater confidence in even the best driver.
Most powerful brakes ever fitted to a Production Mustang
Reducing unsprung mass is key to improving responsiveness, but a balance must be struck between taking mass out of a suspension and delivering truly capable braking performance. Shelby GT350 features the most track-credible brake system ever offered on a production Mustang, consisting of two-piece cross-drilled iron rotors with aluminum hats – the largest rotors Ford has ever put on a production Mustang. Massive 394-millimeter front rotors and 380-millimeter rear rotors are a floating-type and are pin-driven to the aluminum hats to greatly reduce heat transfer to the bearings. These rotors are clamped by six-piston fixed Brembo calipers with integrated caliper bridges at the front and four-piston units at the rear. Dedicated ducting assists in cooling the brakes front and rear for maximum performance.
“These cars can be driven by any driver on any track in the world – with virtually no fade,” remarks Brent Clark, suspension and vehicle dynamics technical specialist.
Wheels and tires fit for the track
Shelby GT350 makes use of extra-stiff 19.0-inch cast aluminum-alloy wheels – 10.5 inches wide in front, 11.0 inches in the rear – clad in Michelin Pilot Super Sport tires with GT350-specific sidewall construction, tread face and compound. The custom tires are designed to deliver maximum grip on the road or for weekend track days.
Shelby GT350R raises the standard even further. It wears carbon fiber wheels, making Ford the first major automaker to introduce this innovative wheel technology. The hand-laid wheels are 19.0 inches in diameter – 11.0 inches wide at the front and 11.5 inches at the rear, each fitted with custom formulated Michelin Pilot Sport Cup 2 tires. Combined, these wheels eliminate approximately 60 pounds of unsprung weight compared to the aluminum-alloy wheels and Michelin Pilot Super Sport tires on Shelby GT350.
Stiffer chassis
The new platform is the strongest in the history of the Mustang brand, with torsional stiffness increased 28 percent over the previous model. That stiff structure ensures the suspension geometry remains consistent even under the loading caused by hard driving. Shelby GT350 takes that philosophy further – with added bracing to increase overall stiffness. A new lightweight aluminum tower brace connects the shock towers and firewall, and improves front end stiffness. When a lower hood was called for to improve aerodynamic performance, Ford Performance re-engineered the grille opening reinforcement with a carbon fiber composite structure that is 24 percent lighter than the base Mustang while maintaining the stiffness of steel. It is finished so well a beauty cover is not needed – eliminating another 1.9 pounds.
