Grand Sport history

Envisioned by legendary Corvette engineer Zora Arkus-Duntov as a factory-built, lightweight and race-ready production model that would trump domestic and foreign road-racing competitors, the original Chevrolet Corvette Grand Sport was a promising idea that led to the production of five special prototypes in 1963. The project was later shelved, following GM's agreement to stay out of manufacturer-backed motorsports.

The five prototypes were based on the styling of the 1963 Corvette and were hand-assembled under Duntov's watchful eye. But while they looked like production models, the prototypes were purpose-built race cars that shared little with their assembly-line cousins. Duntov also oversaw the Chevrolet Corvette Grand Sport engine program that featured a special, 377-cubic-inch small-block V-8 with side-draft carburetors.

Although never officially sanctioned by General Motors, the five Grand Sport prototypes saw extensive racing experience throughout the 1960s in the hands of "private" racers who had strong contacts within Duntov's engineering circle. All five original cars are accounted for today and are among the most valuable in the collector market.

Chevrolet offered a limited-edition  production model in 1996, commemorating the original racing cars and marking the end of the C4 era in Corvette production. All of the 1,000 examples were painted Admiral Blue and featured a white center stripe and red "hash mark" graphics on the left front fender, a graphic scheme that mimicked the look of some of the original race cars.
