                                  Jaguar car

Jaguar began producing R models in 1995 with the introduction of the first XJR. Powered by a supercharged 6-cylinder engine, the car produced approximately 322 horsepower. With the revamped line of engines, the powerplant would be based on an eight-cylinder engine with supercharger from 1997 to present. The 1997–2003 XJR produced 370 horsepower (276 kW) and 385 pound-feet (522 N·m) of torque, taking the car to 60 mph (97 km/h) in 5 seconds. The new aluminium bodyshell from 2004 to 2009 and increased power to 400 hp (298 kW) and enhanced computer systems decreased the time to 60 mph (97 km/h) to 4.8 seconds. Starting after year 2000, XJRs were equipped with Jaguar's CATS (Computer Active Technology Suspension), which helped firm up the ride in sporty driving without compromising comfort during day-to-day use.
The first XKR was introduced in 1997 and kept with the same power increases as the XJR except for after 2006 the power in the XKR was boosted to 420 hp (313 kW). The S-Type R had a short production run from 2003 to 2008, and came equipped with the same 400 horsepower (298 kW) supercharged V8 as the other R models. It was replaced by the XFR, featuring a 5.0 L supercharged V8 producing 510 hp (380 kW).
