This summer the most powerful Mustang ever will go on sale, and Ford announced today that it would have 25 more horsepower than originally estimated. The Shelby GT500 was just ran through the Society of Automotive Engineer’s ringer of tests and came out the other end with an official rating of 500 hp and 480 ft-lbs. of torque. The supercharged 5.4L V8 uses a roots-type supercharger providing a not insignificant (for OEM) 9 lbs./square inch of boost. Many of the engines components were also borrowed from Ford’s supercar, the GT.
That's mighty stout! No doubt the Viper and Z06 will still spank it around a race track, but the 'Stang should cost considerably less than either of those cars, as Ford estimates it will start in the "low 40s".
