The Jaguar D-Type is a sports racing car that was produced by Jaguar Cars Ltd. between 1954 and 1957. Designed specifically to win the Le Mans 24-hour race, it shared the straight-6 XK engine and many mechanical components with its C-Type predecessor. Its structure, however, was radically different, with innovative monocoque construction and slippery aerodynamics that integrated aviation technology, including in some examples a distinctive vertical stabilizer.

The Jaguar C-Type is a racing sports car built by Jaguar and sold from 1951 to 1953. The "C" stands for "competition".
