The 2009 Chevrolet Corvette ZR1 (www.chevrolet.com) is the fastest, most powerful Corvette ever made for public consumption. The ZR1’s 6.2-liter, supercharged V-8 engine, dubbed the LS9, produces 604 ft lbs of torque at 3,800 rpm, which propels the 3,324-pound car to 60 mph in 3.4 seconds. The pushrod motor also develops 638 hp, enabling Chevrolet to claim a top speed of 205 mph. A polycarbonate window on the ZR1’s carbon-fiber hood showcases the new engine, and a low front splitter, vented front fenders, and black-and-blue badges that read “Supercharged ZR1” further distinguish the car from lesser Corvettes. Rarity also sets it apart: Only 338 of the more than 3,900 Chevrolet dealers in the United States will offer the car, at a price of about $105,000.
