Somewhere in the second part of 1959, project XP-720 begins at GM Styling, to design a production Corvette based on Bill Mitchell’s Sting Ray racer. It would become known as the C2 or second generation Corvette. In October of that same year, a clay mock-up of project XP-720 is completed and put on display for General Motors’ management viewing. This early effort was essentially the Stingray Racer with a coupe top.
