Chevrolet Corvette SS
The 1957 Corvette SS was Duntov's technical tour de force. Originally conceived to take on Jaguar and Mercedes at the 24 Hours of Le Mans, the SS was a stunning machine, both visually and mechanically.
A featherweight magnesium body enveloped a tubular steel space frame that featured coil-over-shock front suspension, a de Dion rear axle and inboard-mounted aluminum drum brakes. A fuel-injected small-block V8 resided under its long, sloping hood.
The SS made its maiden voyage at Sebring, where suspension problems forced its retirement after only 23 laps. But there was worse news in store: the Automobile Manufacturers Association announced its opposition to factory involvement in motorsports. The SS project was shelved - although the SS was resurrected long enough to lap Daytona International Speedway at 155 mph during opening-day ceremonies in 1959.
