The new Z06 is America's fastest production car.

Packing 650 horsepower and 650 pound-feet of torque, GM has confirmed the new 2015 Chevy Corvette Z06 is the most powerful car its ever built and promises to be America's fastest production car. Jordan Lee, chief engineer for Small Block engines, says: "the LT4's supercar performance numbers are achieved with an engine that is nearly the same size as the very compact LT1 engine introduced in the 2014 Corvette Stingray.

The power density of the LT4 makes it one of the smallest and lightest 650-hp engines in the industry." In fact, the new Z06 is in esteemed company when it comes to raw power, bested only by the LaFerrari, McLaren P1, Porsche 918 Spyder, Ferrari F12, Lamborghini Aventador, and Ferrari FF, while ranking higher than the McLaren 650S, SRT Viper and Lamborghini Huracan. Arguably more impressive is the 6.2-liter supercharged V8's torque. Chevy says 457 lb-ft is available at idle with 96 percent arriving at 2,800 rpm and peak torque at just 3,600 rpm.

"Torque is the pulling power of an engine and the LT4's abundance of it at every rpm in the engine's speed range helps the 2015 Corvette Z06 accelerate quicker and respond nearly instantaneously," said Lee. "It's the very definition of power on demand." Chevy has yet to release pricing and performance specs (a sub three-second 0-62 mph is a certainty), but the 2015 Corvette Z06 looks set to be the performance bargain of the decade.
