Background
The XJ8 has been described as the perfect blending of Jaguar’s tradition with modern technology. Its silhouette would still have been familiar to Jaguar founder Sir William Lyons, even though he died 12 years before the XJ8 was launched. That’s down to the famously conservative evolution of Jaguar’s flagship executive saloon. The XJ6 always had an elegant and stately shape, so why mess with it? In fact, Jaguar’s staunch and puritan customers usually moaned endlessly when they tinkered even mildly with the formula – though few complained about the XJ8’s new appointments when it arrived in 1997.
Chief among these was the new AJ-V8 engine lifted from the XK8 – launched the previous year. Available in 3.2-, 4.0- and 4.0-litre supercharged form, power ranged from 240bhp to a whopping 370bhp from this joyously revvy over-square, aluminium V8. Nikasil cylinder liners were originally used but were replaced with conventional cast iron alternatives after high-sulphur fuel led to well-documented failures. It was a reliability blight that hit many engine makers across Europe in the mid-late 1990s, including BMW. The problem was soon solved and the engine has since gone on to power some of the most exciting and well-received Jaguar models of the past twenty years.
