After the successes achieved in endurance races with the C-Type, Jaguar developed an even more efficient and aerodynamic car, called the D-Type. If the main objective was the 24 Hours of Le Mans - which Jaguar had already won in 1951 and 1953 with the C-Type, the American market was also an excellent incentive to prepare the new model. The D-Type was in fact an extremely effective racing car, which gave Jaguar three more victories at Le Mans, in 1955, 1956 and 1957, the last two thanks to the Ecurie Ecosse. The D-Type was very successful, as hoped by the manufacturer, also in the United States, where it took part in important races such as the 12 Hours of Sebring. In its fairly long career, the D-Type received several aerodynamic configurations, and was also produced in a road version with the abbreviation XKSS.
