638 hp/205 mph on the test track
ZR1 is powered by a 6.2 Liter LS9 aluminum block V8 equipped with a four-lobe Eaton® Twin Vortices Series™ supercharger with intercooler. It delivers an SAE-certified 638 hp at 6500 rpm and 604 lb.- ft. of torque at 3800 rpm. The engine employs lightweight titanium intake valves and connecting rods and contains a high-performance dry-sump oil system, which distributes pressurized oil from an external reservoir to protect vital components under high-g driving conditions.
"The Corvette ZR1 is a monster. And the Corvette ZR1 is a lamb. How's that? Putter around town, keeping its supercharged LS9 6.2-liter V-8 below 3000 rpm, and it's as easy to drive as any sports car. But dip hard into the throttle and the ZR1's exhaust butterflies open while the car unleashes its full 638 bhp and 604 lb.-ft. of torque to the rear tires - along with a glorious, ripping exhaust note that's music to any enthusiast's ear." -Road & Track
