Holy surprise, Batman! GM bit the bullet and confirmed those 2008 Corvette ZR1 numbers for us. As we expected, the supercharged V8 will be putting down 620 hp and 595 lb.ft. of torque. And also as expected, the car will rocket to a 200 mph top speed. It's further expected to end world hunger, invent perpetual motion, and discover the origins of life. Seriously! 595 lb.ft. of torque can do that!
