The C6.R ZR1 GT2, if you were to use its full name, was the model used in the last four years before the Corvette C7.R was introduced, and had a slick sequential manual operated by paddles that was combined with the rear differential to create a rear transaxle. This style of transaxle eventually made it into the road-going Corvette, especially the Grand Sport and ZR1 of the C7 generation.

In 1969, Chevrolet changed the perception of Corvette forever by introducing the ultra-powerful ZL-1 Corvette with a 427 CI engine producing 585 horsepower! The 1969 ZL-1 Corvette came equipped with an entirely new big-block engine option that produced more horsepower than any Corvette that had come before it. Any Corvette, when ordered with RPO ZL1, came fitted with an all-aluminum 427 C.I. engine that featured a dry-sump oil system and which weight approximately 100 pounds less.
