The 2011 Ford 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.

The 2011 Ford Shelby GT500 combines power and fuel economy into one impressive package. This 2011 Ford Shelby GT500 will be the first modern Shelby without the gas guzzler tax, thanks to the EPA-projected 23 mpg highway and 15 mpg city it will deliver. This is up from 22 mpg highway and 14 mpg city for the 2010 model.

New for 2011 is an SVT Performance Package for enthusiasts who want even more performance out of their Ford Shelby GT500 for racetrack-ready driving dynamics. Complete with all-new Goodyear Eagle® F1 SuperCar G: 2 tires that SVT engineers worked directly with Goodyear to develop, the car is ready to race. The tires offer superb dry traction and precise handling, complete with a race-inspired high-performance tread compound.

The optional package also offers unique styling, lighter wheels, a higher rear axle ratio and stiffer springs, and it is available on both the convertible and coupe. Data show the 2011 Ford Shelby GT500 coupe with the SVT Performance Package is 3.0 seconds faster per lap than the 2010 Shelby GT500 on a 2.3-mile test track.

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 2011 Ford Shelby GT500 convertible model 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.
