Jaguar XJ6 (XJ40 - 1986)
The Jaguar XJ (XJ40) is a luxury sedan manufactured by Jaguar Cars between 1986 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 instrumentation)
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.
Mechanicals:
AJ6 4.0 L engine (in a 1990 Daimler)
Initially, only two engines were offered across the XJ40 models: a 2.9 L and a 3.6 L version of the AJ6 inline-six. In 1990, these were changed to 3.2 L and 4.0 L versions. In 1993, the XJ12 and Daimler Double Six (both equipped with the Jaguar V12 engine) were added to the available models.
During the development of the XJ40, British Leyland had considered providing the Rover V8 engine for the car, which would have eliminated the need for future Jaguar engine production. The XJ40 bodyshell was allegedly engineered to prevent fitting V-configuration engines such as the Rover V8; this delayed the introduction of the V12-powered XJ12 until 1993.
The automatic gearbox used in the 2.9 L, 3.2 L and 3.6 L six-cylinder cars was the four-speed ZF 4HP22. On the 4.0 L, the four-speed ZF 4HP24 was used. A stronger automatic gearbox was required for the V12-equipped cars, and the four-speed GM 4L80-E was selected. The manual gearbox fitted to early cars was the five-speed Getrag 265, while later cars received the Getrag 290.
The automatic transmission selector was redesigned to allow the manual selection of forward gears without accidentally selecting neutral or reverse. This new feature was dubbed the "J-Gate" and has carried over to more recent Jaguar models.
Exterior:
The curvaceous lines of the outgoing Series XJ were replaced by the more angular, geometric shape of the XJ40. The nose of the car would accommodate either matched pairs of round headlights, or rectangular single units; the latter were fitted to the higher-specification Sovereign and Daimler trim levels, and also to all cars for the US market.
The bumper is a visually distinct black-rubber-covered bar that runs the full width of the car and incorporates the sidelights and indicator lights. The bonnet is hinged at the front. Window frames are either chromed or black, depending on model. Rain gutters, door mirrors, and door handles are also finished in chrome. All XJ40s have a chrome surround for the windscreen and a single windscreen wiper.
Early low-specification cars were fitted with metric-sized steel wheels and plastic wheelcovers. From 1991, the wheels were changed to non-metric sizing.
