GM is rumored to be debuting the all-new 2014 C7 Chevrolet Corvette at the Detroit Auto Show in January to be on sale summer or fall 2013. To celebrate the end of the C6 dynasty, Car and Driver’s Technical Editor, Michael Austin, rounds up the best of the special editions for a fond tribute. He rounds up the 505 horsepower Z06 and the 628 horsepower ZR-1 for some exercise around the track while talking about what makes each car so special.
