Like the coupe, the 2007 Ford Shelby GT500 convertible will have a supercharged 5.4-liter V8 that generates 475 horsepower and an estimated 475 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, meaty front vented Brembo 14-inch disc brakes with 11.8-inch rear discs, and standard 18-inch wheels wearing 255/45 tires up front and 285/40 rubber in back. It is, of course, a rear-wheel-drive beast, riding on a retuned MacPherson strut independent front and solid axle rear suspension located by a Panhard rod. 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. To that end, Ford says that the suspension has been validated on the track, courtesy of the Mustang FR500C, which recently won the championship in the Grand-Am Cup Series.
