Overview: 2015 Ford Mustang Shelby GT-350
This is the overview page for the 2015 Ford Mustang Shelby GT-350. Rumors, news, reviews, road tests, specifications, videos, awards, and other relevant information will all be included here as they become available.
The man himself may no longer be with us, but Caroll Shelby’s legacy of working with Ford to create some serious performance machines lives on with the latest entry into the portfolio, the all-new Ford Mustang Shelby GT-350. Unlike the previous generation’s Shelby Mustang, the GT-500, the GT-350’s primary objective isn’t massive horsepower numbers and straight line acceleration. Instead, the GT-350 is designed from the ground up to be a road course terror, and this little pony has the goods to carve through corners with the best of them. The existence of the GT-350 has been a poorly-kept secret for months now, with spy photographers spotting the car testing at the famed Nurburgring on multiple occasions, but now we’ve got official word from Ford on the new car’s imminent arrival, and well as a handful of details on what to expect from the newest top-spec factory Mustang.
On the powertrain front, the GT-350 gets an all-new and very trick naturally-aspirated 5.2-liter flat-plane crank V8 – a production first from Ford, and the kind of tech you’d find under the hood of a Ferrari 458 Italia. Perhaps taking a page from the Hellcat playbook, Ford is not specifying exact output at this time, only stating that the engine will produce “more than 500 horsepower” and "a torque peak above 400" pound-feet. A six-speed manual gearbox and a Torsen limited-slip differential will be standard. Curiously, while Ford proclaims the new GT-350 as “an all-day track car that’s also street legal”, an engine oil cooler, differential cooler and transmission cooler are included only if you opt for the Track Pack options package on top of the standard-spec GT-350.
Boasting the stiffest chassis in the company’s history, the GT-350 will feature a wider front track, along with recalibrated spring rates and bushings all around, as well as a substantially lower ride height than the Mustang GT. The GT-350 will also receive adaptive MagneRide dampers, a first for Ford and much like what you’d find on a C7 Corvette. These dampers allow the driver to adjust suspension stiffness when required and also provide their own intelligent real-time damping adjustments, and their performance in other vehicles bodes very well for what one might expect from the GT-350.
To make sure the pony can stop as well as it can go, the GT-350 will receive the most track-capable braking system ever offered from Ford. The system is comprised of 15.5-inch rotors up front, clamped by Brembo six-piston fixed calipers with integrated caliper bridges, while 14.9-inch rotors with four-piston calipers can be found in the rear.
Inside, an all-new drive-mode system allows selection of five unique settings that change the characteristics of the ABS, stability control, traction control, steering effort, throttle mapping, MagneRide tuning and exhaust settings, although it is unclear at this time if you’ll be able to mix-and-match to create custom presets. Recaro sport seats, a flat-bottomed steering wheel, a new set of gauges and a de-blinging of the shiny surfaces inside to reduce reflections are all part of an effort to make the GT-350 as much of a driver’s car as possible.
Externally, the GT-350’s form has truly followed function, with extensive aerodynamic optimization of the car in order to increase downforce and maximize cooling. All-new bodywork from the windshield forward includes re-sculpted fenders, hood, and front fascia to help reduce the car’s aerodynamic signature and a new front splitter and ducted belly pan help to press the GT-350 to the pavement at speed.
We will undoubtedly have more updates regarding the Shelby GT-350 in the near future as Ford dishes out the specifics. In the meantime, check out the press release from Ford below (which includes a brief explanation of why a flat-plane crank is a good thing to have in a performance car) for additional details.
Shelby GT350 Mustang: The Legend Returns
• All-new Shelby® GT350 Mustang is a thoroughbred capable of tackling the world’s most
challenging roads and racetracks
• GT350 is powered by a unique, high-revving flat-plane crankshaft 5.2-liter V8 engine that will produce more than 500 horsepower – the most powerful naturally aspirated Ford production engine ever
• Advanced materials, MagneRide dampers, aggressive brakes and finely tuned aerodynamics push the performance of Mustang to previously unmatched levels
LOS ANGELES, Nov. 17, 2014 – One of the most iconic performance Mustang nameplates of all time is returning, Ford confirmed today with the reveal of the all-new Shelby® GT350
The original Shelby GT350 introduced in 1965 established 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."
Early in development of the GT350, it was decided 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 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-degree 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 more than
500 horsepower, with a torque peak above 400 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," said Hameedi.
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 input. 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, 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 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 at the track.
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.
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 is 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 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 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
