While the ZR-1 badge was sitting out the Corvette’s fifth generation, a lot changed. A 400-horsepower engine was no longer enough to make a splash. So in 2009, GM revealed a new Corvette ZR1 (no hyphen this time around) with a supercharged 6.2-liter small block making 638 horsepower. It was capable of reaching 205 mph. The ZR1 badge was back, and anybody could see it meant something serious.
