The airy, spacious yet private XJ cabin area is enhanced by the panoramic, heat-reflective tinted glass roof. It extends to the full width of the car and sweeps as far back as the rear seat area, filtering UV rays and flooding the interior with natural light. In addition, the black roof pillars create the impression of a floating roofline, emphasizing the long, low and wide profile of the XJ.
This stunning design was fully imagined before a single physical panel was formed. The XJ was constructed virtually in one of the world’s most advanced vehicle design simulators at the Jaguar Virtual Reality Center. There, every component was modeled in over 43,000 separate 3D simulations, and close to 2.5 million miles were covered on virtual journeys across the world’s most harsh and arduous terrain.
