A new generation will bring a welcome shift in design for the next XJ, which desperately needs a more muscular look to match its athletic moves. The present iteration has an extremely capable chassis, but its interior and exterior designs are stuck in the past. The next-generation car will still use the current XJ sedan's aluminum underpinnings, but it will gain more modern lines conceived under the supervision of Jaguar design chief Ian Callum. A lineup of engines including a Volvo-derived in-line six and updated proprietary V-8s will provide the propulsion when it arrives in 2009.
