Background
Most aficionados know that the Jaguar XJ6 was the last model to have benefitted from the full-throated involvement and ultimate sign-off from the marque’s founder and patriarch, Sir William Lyons.
Fewer still may be aware of Lyons’ level of personal investment in, and attachment to, the model.
Although Lyons would live a full 17 years beyond the XJ’s launch in 1968, he fully retired in 1972. He would later say of the flagship saloon, “Without any doubt at all, the XJ6 is my personal favourite. It comes closer than any other to what I always had in mind as my ideal car.”
The Daimler versions of Jaguar’s XJ8 (X308) were built using the same excellent chassis and choice of terrific V8 engines as the eponymous Coventry cat and, together with their Jaguar stablemates, the X308 Daimlers were the last of the XJ line to be unmistakably part of the Lyons’ lineage.
The styling was a development of the traditional XJ three-box shape, albeit brought up-to-date in a particularly handsome and appealing way.
This meant the return of four round headlamps set under cowls into a wonderfully low bonnet, plus the low roofline, wrap-around rear lights and the long, sloping boot lid that give Jaguars and Daimlers their distinctive profile.
With the ‘standard’ cars powered by either a 3.2-litre V8 engine with 240bhp and 233lb/ft of torque or a 4.0-litre V8 with 290bhp and 290lb/ft, the XJR (Jaguar) and Super V8 (Daimler) iterations continued the tradition of offering something monumentally powerful to those who wanted it.
The supercharged engine developed 370bhp and 387lb/ft, enough to get a whole lot of metal, leather, glass and wood to 60mph in 5.6 seconds on its way to a 155mph restricted top speed.
Most sane people were, and remain, of the opinion that there are few more luxurious and epically memorable ways to experience warp-speed mid-range acceleration than a supercharged X308.
Even the well-known shepherd, turnip grower and home-brew salesman Jeremy Clarkson said that the supercharged X308 was, "Faster, in the real world, than a Ferrari F355... [and the] fastest saloon I've ever seen.”
