Chevrolet will over-deliver when the 2009 Chevrolet Corvette ZR1 goes on sale. When this history-making supercar was introduced at the North American International Auto Show in Detroit earlier this year, the official output claimed was 620 horsepower, good for 100 horsepower per liter of displacement. Now that the LS9 V-8 has completed SAE certification, the final output is set at 638 horsepower and 604 pound-feet of torque. Certain to fuel automotive fantasies for decades to come, this supercharged engine stands as the most powerful ever manufactured by General Motors.
