C6 ZR1. My absolute favorite of all times.

Model year 2009 saw the return of the ZR1 (now without the hyphen) badge on the C6 Corvette. This time, Chevrolet strapped a supercharger on a 6.2-liter V-8 producing a whopping 638 hp and 604 lb-ft of torque. The roof, hood, front splitter, fenders, and rocker panels were all made of carbon fiber. Magnetic dampers, Brembo carbon-ceramic brakes, and the largest wheels ever placed on a production Corvette (at the time) were all standard equipment. When Motor Trend tested the 2009 ZR1, we were impressed with the supercharged Corvette's 3.3-second 0-60 time, 11.2-second quarter-mile time (at 130.5 mph), and 97-foot stopping distance from 60 mph—still very impressive numbers today. The 2009 ZR1 was so good it beat the Ferrari 599 GTB in a comparison test.
