The XJ is dead, long live the XJ! Last year, Jaguar was unveiling the new version of the XJ, a superb creation in everybody’s opinion... Three engines are available, ranging from 385- to 510-hp. Of course, luxury, prestige and comfort come factory standard. Each of the trim levels is offered with a regular or long wheelbase. The handling, especially in the Supersport version, is very, very good.
