From Jaguar press: Following the success of the factory team D-types in winning Le Mans, Jaguar built a number of D-types for sale to private competitors. A production line was set up and 87 cars built. However, sales were slow and the company decided to convert unsold D-types to high-performance road cars that could also be raced.
The new model, called the Jaguar XKSS, was announced on January 21, 1957. The chassis was virtually identical to the racing D-type with four-wheel disc brakes, racing wheels, four-speed all-synchromesh gearbox and a 37-gallon fuel tank. The 3.4 liter, six-cylinder, twin-cam engine had three Weber carburetors and developed 262 horsepower. Aluminum-bodied, it weighed approximately 2000 pounds.
Only sixteen XKSS models were built before February 12, 1957, when a fire at the Jaguar factory destroyed the remaining D-types.
The American actor Steve McQueen owned a Jaguar XKSS for personal use.
