1963 Corvette Grand Sport
Some of the iconic American sports car’s earliest forays into racing were snuffed out before they ever truly began. The 1963 Corvette Grand Sport, a Zora Arkus-Duntov designed rendition, of the C2 was staged for track domination, both at home and abroad.
The Corvette Rondine concept was built by Pinanfarina and introduced at the 1963 Paris Motor Show. The car started life as a 1963 split-window Corvette, which is all the more unusual because Chevrolet introduced the split-window coupe at the same time that Pinanfarina was introducing a custom-built Corvette based on that very same platform.
