DETROIT, MI - General Motors has released track results of the forthcoming 2015 Chevrolet Corvette Z06, saying the car accelerates from a rest to 60 mph in 2.95 seconds with an eight-speed, automatic transmission. It hits 60 mph in 3.2 seconds with a seven-speed, manual transmission.

This basically makes it the fastest production car GM has ever tested at its 2.9-mile Milford Race Course, the automaker says.

"The Corvette has long been known as America's sports car," Mark Reuss, General Motors' executive vice president of global product development, said in a statement. "With the capability of the new Z06 rivaling the best performance cars in the world, we will also be America's Supercar."

GM said the new Corvette Z06 also does a quarter-mile in under 11 seconds.

The Detroit automaker says it achieves these feats behind an aerodynamic body and a supercharged, 650-horsepower engine.

"The defining aspect of driving the Z06 is seamless integration of power, technology and aerodynamics," Tadge Juechter, Corvette chief engineer, said in a release. "As a result, the Z06 delivers ferocious acceleration, tenacious handling, and high-speed stability that few cars can match."

The sports car goes on sale early next year with a $78,995 price tag. A convertible version of the Corvette Z06 goes on sale in the second quarter of 2015 for $83,995.
