Chevrolet has a few upgrades in store for the mighty 2012 Corvette ZR1. One of which is a set of optional Michelin Pilot Sport Cup Zero Pressure Tires. Coupled with the the Performance Traction Management (PTM) system, the 2012 ZR1 is going to be one fast grippy guppy.
Chevrolet wanted to find out how the new car handles one of the worlds most exciting roads, so a trip to Germany and a ticket to the N?rburgring were in order. In 2008, a Corvette ZR1 ran around the infamous track in 7:26.4. The 2012 car blew that time away with a 7:19.63 blast around the 'Ring - that's a six-second improvement, for those who don't feel like doing the math.
