The Corvette Z06 Is Underrated... By 25 Horsepower

Remember when we said that GM didn't have exact power figures on the 2015 Chevrolet Corvette Z06? The guesstimates were around 625 horsepower and 635 pound-feet of twist. Nope. This leaked SAE dyno chart shows the supercharged V8 putting out 650 horsepower and 650 pound feet of torque. 'Murica!

The new LT4 is a serious bump over the utterly insane LS9 and completely decimates the LS7. But, 500 lb-ft at 1,500 rpm? Yes, Five-hundred-pound-feet-at-fifteen-hundred-rpm.

It's no surprise that GM engineers we spoke with earlier this year say the new Z06 walks away from the old ZR1 around around the Milford Proving Grounds. But it's not all about stonking 0-60 times and quarter-mile runs. The Z06 will dance, and that's what we're looking forward to even more than a warped face and a crushed spine.
