The Jaguar XJ220 is a supercar produced by Jaguar luxury marque in collaboration with Tom Walkinshaw Racing as Jaguar Sport between 1992 and 1994.
It held the record for the highest top speed of a production car (350 km/h, 217 mph) until the arrival of the McLaren F1 in 1994.
The production version of the car was first shown to the public in October 1991 after undergoing significant changes. The most obvious of which was a completely different drivetrain and the elimination of the scissor doors. TWR was charged with producing the car and had several goals/rules in producing the car: the car would be rear wheel drive instead of all wheel drive; turbocharged V6 instead of the big V12; and performance goals of over 200 mph (300 km/h), 0 to 60 mph (100 km/h) under 4 s, and the lightest weight possible.
The 6.2 L V12 had been judged too difficult to get past increasingly strict emission regulations and there were also reportedly some design problems caused by the size of the power plant. It was replaced with a Tom Walkinshaw-developed 3.5 L V6 based on the engine used in the Rover Metro 6R4 rally car and fitted with twin Garrett T3 turbochargers, generating 549 bhp (409 kW) of maximum power at 7000 rpm and 473 ft·lbf (641 N·m) of torque at 4500 rpm.
This engine was not only the first V6 in Jaguar's history, but also the first to use forced induction. In spite of the smaller displacement and half the number of cylinders, the engine produced more power than the V12 would have. However, potential customers judged the exhaust note to be harsh and the lag from the turbos to be an annoyance. Also missing from the production version of the car was the Ferguson all wheel drive - the production car had only rear driven wheels, through a conventional transaxle - and the ABS.
