The Jaguar XKSS was a road-going version of the Jaguar D-Type racing car.
Following Jaguar's withdrawal from competition at the end of the 1955 season, a number of completed and partially complete D-types remained unsold at the Browns Lane factory. In an attempt to recoup some of the investment made in building these unused chassis, and to exploit the lucrative American market for high-performance European sports cars, Sir William Lyons decided to convert a number to full road-going specification. Only minor changes were made to the basic D-type structure: the addition of a passenger side door, the removal of the large fin behind the driver's seat, and the removal of the divider between passenger and driver seats. In addition, changes were made for cosmetic, comfort and legal reasons: a full-width, chrome-surrounded windscreen was added; sidescreens were added to both driver and passenger doors; a rudimentary, folding, fabric roof was added for weather protection; chromed bumpers were added front and rear (a styling cue later used on the E-type); XK140 rear light clusters mounted higher on the wings; and thin chrome strips added to the edge of the front light fairings.
On the evening of 12 February 1957, a fire broke out at the Browns Lane plant destroying nine of the twenty-five cars that had already been completed or were semi-completed. Most of the surviving 16 XKSS were sold in the USA.
The American actor Steve McQueen owned a Jaguar XKSS for personal use, painted British racing green. He referred to the car as the "Green Rat".  In 2010 and 2011 it toured the United States as part of the "Allure of the Automobile" exhibit.
