The Corvette ZR1 is the fastest, most ridiculously cool production Corvette ever produced. After taking the ZR1 for several hot laps of the Lutzring in Milford, we'd go as far as to say it's one of the fastest vehicles we've ever driven. Journalists aren't the only ones who have driven the ZR1 either, as a select few General Motors employees get to drive the 638-hp supercar as their daily driver. One GM worker by the name of Karen took the ZR1 to an autocross event in Ohio and put the supercharged LS9 Corvette through the cone gauntlet. Hit the jump to see and hear the ZR1 zip through the course. Unfortunately, the camera operator didn't zoom in on the Vette or follow it very well, but it's worth your :58 to watch if only to listen to the ZR1 come off the line. Thanks for the tip, Mark!
