The Jaguar XJ

A Jaguar near and dear to my heart, because we have a 1988 XJ6.
The Jaguar XJ was more of a luxury touring car, not the land rockets some Jags were.
They came with the six cylinder and V-12.
But that's not to say the model had no high performance engines.
In 1994 they had a 6.0 L Jaguar V12 engine rated at 318bhp.
In 1995 there was a 326 bhp supercharged version of the straight-6 offered and badged as the XJR.
The X308 Mk II had a 4.0 litre supercharged option that delivered 370 bhp and also a 4.0 that provided 400 bhp.

The Jaguar XK

The Jaguar XK series (XK8 and XKR) is a grand tourer produced by British carmaker Jaguar since 1996. The car was introduced in Geneva Motor Show on March 5th 1996. It is the replacement of the XJS, and is available as a coupé and convertible. Currently in its second generation, the XK8 was the first 8 cylinder vehicle produced by Jaguar, when the Jaguar AJ-V8 engine was introduced.
The 1997 XK8 (project code X100) was available in coupé or convertible body styles and with either a supercharged 370 hp (276 kW) or naturally aspirated 290 hp (216 kW) engine. The supercharged variant is known as the XKR. The first-generation XK series shares its platform with the Aston Martin DB7. Both cars are derived from the Jaguar XJS, though the platform has been extensively changed.
