Dubai – MENA Herald: One of the most iconic performance Mustang nameplates of all times returns as the all-new Shelby® GT350 Mustang and makes its regional debut at the 2015 Dubai International Motor Show this week.
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 Jim Benintende, President, Ford Middle East and Africa. “Every change we made to this car was driven by the functional requirements of a powerful, responsive power plant – nimble, precise handling, and massive stopping power.
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 power plant 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 valve train 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 500 PS, with a torque peak of 542 Nm 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.
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.
“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.
