Background
The final evolution of the much-admired XJ40 platform - which in itself had been in production since 1986 - the X308-generation Jaguar XJ was introduced in 1997, and remained in production across two generations until it was phased out and succeeded by the X350 XJ in 2003.
Whilst externally largely similar to its predecessor, the front end was lightly face-lifted with refined indicator lenses, headlight arrangements and restyled lower air intake, whilst the front and rear bumpers were both changed for this new generation of luxury sedan.
Inside, much remained the same as the X300, though the dashboard was upgraded to a new design - the first time the interior had seen a major update since the original XJ40 - whilst a true glovebox was incorporated into the design for the first time since the passenger airbag was fitted to the original XJ40.
Underneath, only the AJ-V8 engine was available, with the AJ16 I6 and V12 engines having been discontinued prior to the X308’s launch. The V8 was available in either 3.2 or 4.0-litre guise, with the latter being supercharged in the XJR model. In terms of transmissions, most cars were fitted with the ZF 5HP24, though the R model received a Mercedes-Benz 5G-Tronic item to cope with the additional power and torque on offer.
Specifically, the Sovereign - as seen here - represented the pinnacle of the model range, providing the ultimate in luxury and comfort. Inside, more expensive and refined wood inlays featured, with additional trims seen in areas that would be plastic mouldings in lower models. Similarly, the leather was of a higher quality, whilst comfort was order of the day for the suspension, with smaller wheels and high-profile tyres also often fitted for better ride quality.
Externally, the XJ badging was removed, simply being replaced with ‘Sovereign’ whilst additional chrome trims feature around the radiator grill, windows and rear light clusters. An LWB (long wheelbase) variant was also offered, allowing an additional 4” of room in the rear, instantly identifiable by the extended rear doors.
