The fight for pony-car supremacy has been raging for decades. Chevrolet Camaro versus Ford Mustang is a duel without a definitive ending. Battles are fought and won with every new variant and each model year change, yet there’s never enough momentum in any one direction to decide the war. America’s two newest and at the same time, most powerful series-production muscle cars are the 2013 Ford Mustang-based Shelby GT500 and the 2012 Chevrolet Camaro ZL1.

On paper, the $54,995 Camaro ZL1′s 6.2-liter supercharged V8 produces 580hp at 6,000 rpm and 556 lb-ft. of torque at 4,200 rpm, while the $54,200 Shelby GT500′s 5.8-liter supercharged V8 delivers 662hp at 6,250 rpm and 631 lb-ft. of torque at 4,000 rpm.
