Chevrolet Corvette ZR1 with 638 hp

 Corvette ZR1 LS9 Engine

“Not bad” is the first thing I could say about the new Corvette ZR1. They called it the American supercar and for a reason because it was supposed to output 620 hp from a hand built LS9 6.2L supercharged V8 engine. Though 620 hp may have been enough, it turned out to be the bad number, because Corvette ZR-1 outputs nothing less than 638 hp (476 kW). This is the most powerful engine that GM ever built.

“The combination of large displacement and the new, four-rotor design broadens the effective range of the supercharger, allowing the engine to make more power at lower rpm and sustain it throughout the power band. The low-end torque is tremendous and the high-rpm charge from the supercharger is simply amazing.” said Sam Winegarden, GM Powertrain Chief Engineer.

Corvette ZR1 – The American SuperCar

Corvette ZR1 - The American SuperCar

America has a SuperCar, or at least this is what Chevrolet general manager Ed Peper is saying (thinking) after showing to the public the new Corvette ZR1 at the Detroit Auto Show. Corvette is deep inside he blood of every American that needs speed and looks, but the we ZR1 is really business. It comes with a supercharged 6.2-liter V8 engine that sports 620 hp and a 823 NM (595 lb/ft) torque, being able to hit the 200mph speed, while the speedometer has a 220 mph on it.

Corvette’s ZR1 basic stats include a manual six-speed gearbox (race hardened), a high capacity dual-disc clutch or larger brake calipers. The design is great, with a raised carbon-fiber hood and carbon fiber panels prominent inside on the fenders, the roof and front splitter. Consider 19-inch or 20-inch chrome wheels and a dark color for the American SuperCar and it’s looking furious.
