2016 Ford Mustang Shelby GT500

Traditionally, in the pony-car wars, horsepower is firepower—and the more you have, the better to thump your competition. The outgoing GT500 comes packing heat in the form of a supercharged 5.8-liter V-8 pumping out a brutal 662 ponies and 631 lb-ft of torque. Code-named “Trinity,” the blown V-8 is a double-barreled shotgun to the Chevrolet Camaro ZL1’s magnum pistol—an 82-hp and 75-lb-ft advantage that cannot be ignored. The Camaro’s not going anywhere, and neither is the long-running muscle-car rivalry between Chevy and Ford, so the next GT500 will need to maintain its predecessor’s edge.
