In 1986, a newly formed Lister Cars under the leadership of engineer Laurence Pearce began offering a high performance package for the Jaguar XJS. The cars were sold as Lister-Jaguar and 90 customer cars in total were converted. The standard package included: increased engine displacement to 7.0-litres as well as different engine upgrades, a new body kit featuring a spoiler at the rear and flared wheel arches to accommodate wide tyres, a modified suspension system that featured stiffer Koni dampers, an upgraded braking system with ventilated brake discs, and a modofied interior featuring Recaro racing bucket seats and a new steering wheel with optimised feedback.  Performance figures include a 0-97 km/h (60 mph) acceleration time of 4.5 seconds and a top speed of 322 km/h (200 mph). Some customers further got their cars modified with the addition of the Le Mans package. The package included a 6-speed Getrag manual transmission, a new exhaust system and twin-superchargers over the standard package applied in order to extract a power output of 450 kW (603 hp) from the engine.
