The Jaguar D-type, like its predecessor, is a factory-built race-car. It was essentially an up-rated C-type with a more powerful engine plus an improved chassis and more aerodynmic body. The standard D-type was a "one-seater", but in the last year of production, the company offered the Jaguar XKSS which was a "street version" of the racer with two seats, two doors, a full windshield and primitive folding top as concessions to practicality.
Elements of the body shape were used in the iconic E-type which, despite the name, was not technically a descendant of this car.
Production is thought to have included 53 original D-types, 18 team-race cars and 16 XKSS versions.
