2009 Chevrolet Corvette ZR1: Revealed, Officially!

This is the 2009 Chevrolet Corvette ZR1, officially revealed for all the world to see. Powered by a supercharged LS9 6.2L small-block engine, the ZR1 hasn't even received an official horsepower number from the engineers toiling away at the General. All Harlan Charles, project manager for the Corvette team was able to tell us last week was the new high-powered 'Vette engine is "capable of producing at least 100 horsepower per liter. That's at least 620 horsepower, and approximately 595 lb.-ft. of torque." Chevrolet wasn't even able to give us a time on the 0-60. Charles was only willing to say "it's in the low three seconds." The small-block engine under the hood is only able to hit those massive numbers due to the addition of the positive-displacement Roots-type supercharger with a new, four-lobe rotor design plus an integrated charge cooling system that reduces inlet air temperature for increased performance. That's the "go" end, but the "whoa" end is just as impressive. The ZR1 gets some simply huge carbon-ceramic, drilled disc brake rotors. They're so big and are required to be so powerful they're using the same 15-inch-diameter discs found on the front of a Ferrari 599. Except on the ZR1, they go on the 20" tires in the rear. In the front, they'll be getting even larger 15.5-inch-diameter rotors.
