The 2013 Chevrolet Corvette ZR1 will be the pace car for this year's Indianapolis 500--a fitting victory lap as the current sixth-generation Corvette heads for the end of its production run and the end of this version of the ZR1. The Indy pace-car Corvette will wear the 60th-anniversary trim package--an arctic white exterior with silver stripes down the center of the car and a blue interior with suede leather coverings on the steering wheel, center console and in the seats. Changes for the pace car include only the addition of a light bar on the roof, some racing-safety equipment and race logos.
