Background
The XK8 marked a solid return to form for the Coventry company as far as long term enthusiasts were concerned. Launched in 1996 to replace the XJ-S, a car that had never completely won the hearts of Jag lovers (the E Type was a hard act to follow), it was available as a convertible and a coupé.
At the heart of the sleek new model was the also new Jaguar AJ V8 engine, a quad-cam 32-valve al alloy unit of 4-litres. The XK8 was joined by a more powerful XKR in 1998, which featured a supercharged variation of the V8 engine rated at 370bhp. The engine was shared with the XJR saloon but featured a new intercooler and a two-piece driveshaft.
The Eaton supercharger displaced 2-litres and generated 11.9 pounds of boost pressure to contribute to the higher power output. Visual differences from the XK8 included a rear spoiler, mesh front grille and hood louvres on the bonnet for improved airflow to the engine.
The XK8 came standard with 17-inch alloy wheels, while 18-inch (standard on the XKR), 19-inch, and 20-inch wheels were available for the XK8 and XKR at an additional cost. Jaguar's Adaptive Cruise Control was an optional feature available on both models, but all came with a leather interior, burl walnut trim, and side airbags. Alcantara seat panels were optional.
The XK range received a mechanical update in 2002 with the engines in both the XK8 and XKR models being enlarged to 4.2-litres and gaining more power.
Initially, a ZF 5HP-24 five-speed automatic transmission was coupled to the naturally aspirated 4-litre model and a Mercedes W5A580 five-speed transmission to the supercharged version, but in 2002 the new ZF 6HP-26 six-speed automatic transmission was fitted to both versions of the 4.2-litre model.
For 2005, the supercharged coupé received a few mild refinements, but overall it's the same sexy beast capable of sprinting from zero to 60mph in only 5.2 seconds. That's a surprisingly rapid turn of pace considering the XKR's heft (1753Kg) and overall dimensions.
