place, the race was won by a D-Type entered by the small Edinburgh-based team Ecurie Ecosse and driven by Ron Flockhart and Ninian Sanderson, beating works teams from Aston Martin and Scuderia Ferrari. In America, the Cunningham team raced several D-Types. In 1955, for example, a 1954 works car on loan to Cunningham won the Sebring 12 Hours in the hands of Mike Hawthorn and Phil Walters, and in May 1956 the team's entries for Maryland's Cumberland national championship sports car race included four D-Types in Cunningham's white and blue racing colors. Driven by John Fitch, John Gordon Benett, Sherwood Johnston and team owner Briggs Cunningham, they finished fourth, fifth, seventh and eighth, respectively. Although Jaguar withdrew from motorsport at the end of the 1956 season, 1957 proved to be the D-Type's most successful year. 3.8-litre engine Jaguar D-Types took five of the top six places at Le Mans, and Ecurie Ecosse, with considerable support from Jaguar, finished first and second, the best result in the D-Type's racing history. Rules for the 1958 Le Mans race limited engine sizes to three litres for sports racing cars, which ended the domination of the 3.8-litre D-Type. Jaguar developed a 3.0 litre version to power D-Types in the 1958, 1959 and 1960 Le Mans races, but it proved unreliable, and by 1960 no longer produced sufficient power to be competitive. The D-Type never again achieved a podium finish at Le Mans. Its success waned as support from Jaguar decreased and cars from rival manufacturers became more competitive, although from 1960 the D Type continued for a further three years or more to be one of the cars to beat in club racing and national events. XKSS After Jaguar temporarily retired from racing as a factory team in 1956, the company offered the remaining unfinished D-Types as XKSS versions whose additional road-going equipmentincluding a passenger seat, passenger-side door, side windows, full-width framed windscreen and windscreen wipers, trimmed interior, folding hood, and bumpersmade them eligible for production sports car races in America. On the evening of 12 February 1957, a fire broke out at Jaguar's Browns Lane plant and destroyed nine of the 25 cars that were in various stages of completion. With the requisite jigs and tooling also destroyed, this effectively ended production of the XKSS version, although Jaguar later converted two additional D-Types that had not been part of the intended XKSS production
