Among other things, GM styling boss Bill Mitchell was a sports car enthusiast. And like any sports car guy, he could see that Chevrolet’s Corvair sedan provided all the necessary components to create a real two-place sports car: air-cooled flat six, a rear transaxle, a light and compact chassis. Eliminate the back seat, add some authentic sports car styling elements, and there you have it—the Corvair Sebring Spyder, a proper sporting two-seater.
Carrying the internal GM designation XP-737, the Sebring Spyder was created by shortening a production 1961 Corvair floor pan some 15 inches, eliminating the rear seat region and shortening the wheelbase from 108 to 93 inches. (This same shortening technique was used on another GM two-seat concept around that time, the Pontiac Tempest Monte Carlo we featured here.) Racy split windscreens and a fiberglass tonneau section with a center divider and twin headrests closed out the upper bodywork.
