Ford's Special Vehicle Team (SVT) engineers are taking high performance to a new level with the 2011 Ford Mustang Shelby GT500, resulting in a car that has an all-new aluminum-block engine, even better driving dynamics and handling, improved fuel economy and more horsepower than ever.
The SVT team continues to push the performance standards of the Shelby to even higher levels and better refinement," said Jost Capito, director of global performance vehicles and motorsports business development. "All the changes we made reflect a desire for even better handling and outstanding driving dynamics - from weight savings to improved balance.
Weight Savings, New Technology Headline All-New Aluminum Engine :
The 2011 Ford Mustang Shelby GT500 is powered by an all-new aluminum-block 5.4-liter supercharged V-8 engine, which produces 550 horsepower and 510 ft.-lb. of torque, a 10 horsepower increase versus the 2010 model. The engine also is 102 pounds lighter than its predecessor, delivering a better power-to-weight ratio, improved fuel economy, acceleration, handling and steering precision.
"Cutting weight to improve performance is a tradition among hot rodders," said Carroll Shelby, founder of Shelby American. "It might not be as sexy as adding more horsepower or bigger brakes, but shaving pounds off of a car is the single smartest move you can make.
More Engine Sound, Less Road Noise :
For 2011, Ford Mustang Shelby GT500 also benefits from NVH (noise, vibration and harshness) improvements. Overall road noise is reduced by 20 percent versus the 2010 Shelby. Actions undertaken to achieve this improvement include additional sound-deadening material on either side of the instrument panel, additional sound absorption behind interior trim panels, and a rear wheel arch liner to reduce noise on gravel or wet surfaces - all resulting in the driver hearing more exhaust and engine sound and less road and air noise.
The Ford Mustang Shelby GT500 Convertible features enhanced structural rigidity, with lateral stiffness improved by 12 percent versus the 2010 model. The V-brace has been stiffened by adding gussets. The secondary crossmember also has been stiffened, while a front Z-brace has been added, connecting primary and secondary crossmembers. A-pillar stiffening foam has been added to increase rigidity.
The structural improvements to the convertible gave SVT the opportunity to be more sport-oriented in the chassis tuning, without trading comfort. Along with the chassis and structural improvements, the 2011 model also will get standard 19-inch aluminum wheels.
"One of the biggest changes for this Shelby is that the convertible acts and feels like a coupe," said Jamal Hameedi, SVT chief nameplate engineer. "Before, they had a very different character, and the convertible is taking a big step in the sportiness and handling precision area, without degrading the ride."
GT500 gets a new exhaust for 2011, roaring with an even more aggressive sound than the 2010 model. The 2.75-inch exhaust with all-new tuning helped to deliver the additional 10 horsepower.
Added Convenience Content :
New for 2011 is an optional glass roof, providing customers with a less expensive option than a convertible and without compromising the coupe's versatility, headroom or climate-controlled environment.
The specially formulated glass also protects interior fabric material from solar radiation deterioration and discoloration by reducing solar light transmittance. To help improve acoustics and interior quietness, the glass features a layer of vinyl that reduces noise, vibration and harshness.
Other New Convenience Technologies Include :
Standard HID (high-intensity discharge) headlamps
MyKey™ programmable vehicle key
Integrated spotter mirror
Fold-down rear headrests
"Whether you're looking to take the GT500 out on the streets or have some fun at the track," Capito says, "This car will satisfy the most discriminating performance driving enthusiasts."
