Although major revisions (through the X300 and, particularly, the X308 updates) kept the Mark 2 competitive in some areas against its rivals, the basic design dated back to 1986 which meant the car was very quickly being outclassed and losing ground to its rivals, many of which were now two generations advanced from the original competitors of the Mark 2 XJ. For example, since the model had been unveiled in 1986 (at the same time as the BMW 7 Series E32), BMW had launched Mark 3 (E38) and Mark 4 (E65) versions of its 7 Series in 1994 and 2001 respectively all while Jaguar was still producing the Mk 2 XJ. In early 2003, the all-new third generation XJ (known as X350) arrived in showrooms. While the car’s exterior and interior styling were traditional in appearance, the car was completely re-engineered. The new car also saw the return of the fabled XJ6 badge, and with it 6-cylinder power, albeit in a V-configuration. Like the Audi A8’s, the used Jaguar X350’s chassis and body are constructed from aluminium. While some steel is used in some places throughout the chassis, the X350 has a stressed aluminium monocoque/chassis similar in general design to a conventional steel structure, but with two differences; its underbody components are bonded together with aerospace-grade epoxy adhesives while around 3,200 self-piercing rivets are used to create the new XJ’s unibody. This differs from the A8’s construction which uses an aluminium spaceframe to which aluminium panels are then attached.
