2015 Chevy Corvette Z06 is most powerful production GM car ever with 650 hp, 650 lb-ft

Well, consider the cat officially out of the bag. Nearly five months after its debut at the 2014 Detroit Auto Show touting "at least 625 horsepower," the 2015 Chevrolet Corvette Z06 has now been SAE-certified to produce an impressive 650 hp.

For reference, the new Z06 is bested only by the following bits of exotica: the Ferrari LaFerrari, the McLaren P1, the Porsche 918 Spyder, the Ferrari F12 Berlinetta, the Lamborghini Aventador and the Ferrari FF. That's some mighty good company.

Complementing the 650 supercharged ponies is an equally impressive 650 pound-feet of torque. Lovely as that second figure is, we really need to break down where the power is available. According to Chevy, 457 pound-feet of torque is available at idle, while 96 percent of peak torque arrives by 2,800 rpm. Honestly, if the Z06 can't hit 60 in under three seconds, we'll be shocked. Talk about a whole lot to handle.
