The 1963 Chevrolet Corvette Grand Sport: Racing Pedigree Redefined
Historical Context and Development Background
The Chevrolet Corvette Grand Sport was born from a desire to establish Chevrolet's dominance in the world of motorsports. Developed under the vision of Zora Arkus-Duntov, the Grand Sport was an ambitious project aimed at taking on the likes of Ferrari and Shelby in the competitive racing arena of the early 1960s.

Originally intended for a production run of 125 units to satisfy FIA homologation requirements, only five prototypes were completed due to GM's ban on factory-backed racing. These five cars became legendary, each with its own storied racing history.
