The Jaguar XJ (XJ40) is a luxury sedan manufactured by Jaguar Cars between 1987 and 1994. Officially unveiled on 8 October 1986 it was an all-new redesign of the XJ to replace the Series III, although the two model ranges were sold concurrently until the Series III was discontinued in 1992. The XJ40 used the Jaguar independent rear suspension arrangement, and featured a number of technological enhancements (such as electronic instrument cluster). The 1993 XJ6 earned the title of "Safest Car in Britain" as the result of a government survey. When the XJ40 was discontinued in 1994, it was followed by the X300 platform XJ. ==Development== Throughout the 1970s Jaguar had been developing "Project XJ40", which was an all-new model intended to replace the original XJ6. Scale models were being built as early as 1972. Due to the 1973 oil crisis and problems at parent company British Leyland, the car was continually delayed. Proposals from both Jaguar's in-house designers and Pininfarina were received. Eventually, it was decided an internal design would be carried through to production and, in February 1981, the British Leyland board approved £80 million to produce the new car. Jaguar historians claim that the XJ40 was the last car which company founder Sir William Lyons had contributed to during its protracted development phase. The previous generation XJ had been the final Jaguar to be developed wholly under Lyons' leadership - although he continued to take an active consultative role within Jaguar design, long after had retired from the day to day management of the firm following its merger in 1966 with the British Motor Corporation. During development, the XJ40 pioneered significant improvements to the way Jaguar designed, built, and assembled cars. Among these improvements was a 25 per cent reduction in the number of bodywork panels required per car (e.g. three pressings needed for a Series 3 door compared with one for a XJ40 door), resulting in not only a more efficient assembly process, but also a weight saving and a stiffer structure. Greater attention to panel gaps improved the drag factor (reduced from 0.849 Cd to 0.762 Cd), while also improving the fuel economy and lowering wind noise inside the cabin. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jaguar XJ (XJ40)」の詳細全文を読む スポンサード リンク
