The 2007 Ford Shelby GT500 will have a supercharged 5.4-liter V8 that generates 450 horsepower and an estimated 450 lb.-ft. of torque. One special feature of this engine is its aluminum cylinder heads, the same type used in the Ford GT. The Cobra comes with a six-speed manual transmission and standard 18-inch wheels wearing 255/45 tires up front and 285/40 rubber in back. It's a rear-wheel-drive beast, riding on a retuned MacPherson strut independent front and solid axle rear suspension. Ford’s SVT team spent plenty of time modifying the suspension setup, in order to handle the Shelby GT500’s increased performance and power demands. --Brian Chee
