Background
Jaguar’s XJ executive express first broke cover in 1968, and what a glorious big cruiser it was. Refined, elegant and a consummate devourer of motorways it became the go-to vehicle for bank managers and their ilk, while middle-aged geezer boys lusted after them.
The original recipe – nicely proportioned styling, Jaguar’s legendary straight-six engine (in a tres hushed form), a restful suspension set-up, rack-and-pinion power steering and the option of an auto ‘box – was a winner, and one that evolved over the next few decades in terms of both performance and luxury.
The replacement XJ40, introduced in 1987, featured a revamped style with fewer body pressings and improved structural rigidity. It was quieter, more refined and had a more angular aesthetic. In 1994, with Jaguar now under Ford ownership, the model was heavily revised to become known as the X300 and many of the earlier XJ curves returned.
Standard engine options included the AJ6 straight-six, in either 3.2 or 4.0-litre capacities or a Jaguar 6.0-litre V12. But top of the tree was the high-performance XJR (X306) - which employed an Eaton supercharger and an intercooler to increase power in the 4.0-litre to 326PS. It was Jaguar’s first ever supercharged road car.
Driving through a 5-speed manual transmission to the rear wheels, it could devour the 0-62mph sprint in 6.4 secs, on its way to a limited top speed of 155mph. The Getrag manual was standard fit but most of these luxury ‘bahn-stormers were optioned with an automatic gearbox.
To tell them apart from the more “everyday” Jaguar, the XJR (or XJR6 as this generation became known) was given blackened window trims and gutters, a body-coloured surround to a mesh grille and a body-coloured boot lid trim as well as its own XJR badging. The exhaust outlets were necessarily larger and the wheels were special 5-spoke sport alloys.
Over 6,500 XJRs were built before production ended in 1997 and the similar-looking but V8-powered X308 models were introduced.
