are right-hand-drive), while the driver and passenger seat are extremely close together - almost central in the car. Due to minimal sound insulation, an in-car head-set system is fitted. There is no storage space in the car due to its race car like nature.

Ron Grable wrote: "Aesthetically, the XJR-15's interior is breathtaking. Expanses of shiny black carbon fibre woven with yellow Kevlar are everywhere, all fitting together with meticulous precision. Instrumentation is detailed and legibly analogue. The shift lever is less than from the small steering wheel, and the motion between gears is almost imperceptible. The reclined seating position provides excellent forward visibility - over the top of the instrument panel you see only racetrack."
