More black panther than Jaguar, the Super Eight concept breathes some bad attitude into the XJ Long Wheelbase sedan. Created by Jaguar Cars' Advanced Design Studio, the Super Eight explores refinements and creature comforts under a broad, single-piece glass roof. Inside, passengers are coddled in individual seats with inch-thick carpet, chilled champagne, Waterford Crystal, and abundant matte-finished American Walnut trim. Luxurious cow hide covers seats in aniline leather, while velvety nubuck trims the instrument panel, center console, and doors. To provide the soundtrack for a hedonistic escape, a custom 860-watt, 14-speaker Alpine stereo system was engineered with a "no-expense-spared" installation. To give the car the performance its brash exterior warrants, Jaguar fitted a 4.2L/400-hp supercharged V-8. While built to draw attention to the long-wheelbase XJ going in to production, the Super Eight reveals the development mindset expected to be reflected in future models.
