Superformance has formed a sub-brand, Duntov Motors, LLC, to develop a spot-on licensed replica of one of the most famous Corvette models of all time - the hardcore, race-spec 1963 Corvette Grand Sport.
Superformance is famous for building replicas of vintage Shelby Cobras (including Pete Brock's slippery Daytona coupe) and Ford GT40s.
Back in the 1960s, the original Grand Sport project was kept under wraps and was known only be a select few. Corvette chief engineer Zora Arkus Duntov spearheaded the project in 1962 that resulted to five examples of a race-ready 'Vette. These were quietly designed and built by Chevrolet's engineering staff.
Duntov held hopes that the GS would evolve into a factory-backed racer (and even a homologation-special production car).
But as soon as corporate directors knew of the program, they put a stop to it and sold the cars off to private race teams. All the five cars are still around today but each is worth far too much to actively drive or race.
Superformance views its Grand Sport, which closely adheres to the original car, as a continuation series.
Original blueprints for the car were obtained and the engineers crafted body molds from Grand Sport #002, which was converted into a roadster by Chevy engineers shortly before the program ended.
