The second-generation Corvette sold from 1963 to 1967 and came to be known as the Sting Ray. This particular car was born from a handful of experimental and prototype machines that designers/engineers Zora Arkus-Duntov and Bill Mitchell had worked on toward the end of the C1 production run. For Zora, the car had yet to reach its full performance potential in the first generation. There was one big problem: the Automotive Manufacturers Association's ban on allowing production cars to compete in racing. This didn't stop the duo, though, as they and other GM employees dedicated after-hours time to designing and building early Corvette concept racecars.
