This is video of the Corvette ZR1 development team testing the new Super Vette at Germany's famous Nurburgring North Course. There's a bit of a contest going on between manufacturers to see who can lap the "Green Hell" quickest in a production vehicle. While debate about what constitutes a production car rages on, the ZR1 is certainly one of the quickest vehicles to lap the course in OEM configuration. Nissan, which until this lap held the unofficial record with their new GT-R supercar, is sure to challenge the ZR1's time with their uprated GT-R Spec V.

Aren't manufacturer battles fun?
