2009 Chevrolet Corvette ZR1 unveiled
After years of speculation, spy photos, and rumors, General Motors has finally revealed its 2009 Chevrolet Corvette ZR1, which will be on display at the Detroit auto show in January. As expected, the
ZR1 is the most powerful and most expensive Corvette model ever.
An all-new LS9 motor produces
620 horsepower at 6500 rpm and 595 pound-feet of torque at 4000 rpm. Delivering 100 horsepower per liter,
the supercharged 6.2-liter V8 is mated to a close-ratio six-speed manual gearbox with a new high-capacity clutch designed for the increased power. The twin-disc 260mm design provides plenty of clamping power, while maintaining a relatively easy clutch action.
