1957 Chevrolet Corvette SS Project XP-64
Offered by RM Sotheby’s | Coral Gables, Florida | February 2025
In 1956, legendary GM designer Harley Earl bought a Jaguar D-Type (after it finished 3rd at Sebring that year). He wanted to put a Chevy V8 in the car and put it back on track. Instead, Zora Arkus-Duntov imagined what a ground-up Corvette-based racer aimed at the D-Type could be.
The car features a tubular spaceframe wrapped in a one-off magnesium body that carries some of the period Corvette looks. It has independent front suspension, inboard rear brakes, and a 283ci (4.6-liter) V8 that was slightly tuned and fitted with Ramjet fuel injection. It made over 300 horsepower.
Dubbed the Super Sport, the car would go racing, including:
- 1957 12 Hours of Sebring – 59th, DNF (with John Fitch and Piero Taruffi)
And before they could swap a fiberglass body on it and take it to Le Mans, GM pulled out of factory racing. It was donated to the Indianapolis Motor Speedway Museum in 1967, and they are now selling it. The estimate is $5,000,000-$7,000,000. Click here for more info.
