While Ford officials haven't discussed top-speed specs, they have released plenty of engine data that suggests the 2006 Ford Mustang Shelby Cobra GT500 will be a screamer. Providing power is a supercharged 5.4-liter, 32-valve V8 with Ford GT cylinder heads. Horsepower is rated at 450 and torque registers at 450 lb.-ft. Managing all of that oomph is a six-speed manual transmission, and controlling the ride is an independent MacPherson strut front suspension and a multi-link live setup in the rear. Front and rear stabilizer bars are standard, as are 19-inch alloys wrapped in 255/45 tires. Slowing it all down are cross-drilled discs (14-inch front, 13-inch rear) with Brembo calipers.
