Whether you refer to it as the standard-bearer, the flagship or what have you, the XJ is the most posh Jaguar around. No less than four engines are offered: a 340-hp 3.0L V6 and three versions of the 5.0L V8 with 470, 510 and 550 horsepower respectively. The transmission is an eight-speed automatic. All the variations are rear-wheel drive, expect for the V6, which has all-wheel drive. If you like to travel, you will love it in this Jag – regardless of whether you sit up front or in back!
