Corvette CERV II
In the late ’50s, Chevrolet introduced CERV I (Chevrolet Engineering Research Vehicle), which was a Formula I racer with one seat and engine in the back. In 1964, after the GS racing program was canceled, Zora Arcus Duntov, with his team of designers, presented the CERV II (via Motor Trend).
This was a fully functional concept for future racing cars. Duntov knew that Corvette would sooner or later approach the limit of front engine configuration and was a strong advocate of moving to a rear-engine layout while participating in racing.
