Jaguar XJ

Jaguar XJ is a full-size luxury sedan produced from 1968 to 2019, serving for decades as Jaguar’s flagship model. For modern used-car buyers, the key post-2000 generations are the X350/X358 and X351. In February 2015, the one millionth XJ was produced, while the final X351 generation accounted for more than 120,000 units before production ended in July 2019.

The X350 generation, introduced in 2003, marked a major technical shift with an aluminium monocoque body using bonded and riveted construction. This reduced weight compared with traditional steel rivals and improved refinement. Engine options included 3.0-liter V6, 3.5- and 4.2-liter V8 petrol engines, a supercharged 4.2-liter V8 in the XJR, and a 2.7-liter twin-turbo V6 diesel in later European versions. A 6-speed automatic transmission was used across the range, while air suspension contributed to the car’s smooth ride.

The X351 generation, launched in 2009, abandoned the conservative styling of earlier XJ models and introduced a more modern aluminium body structure. Engines included 3.0-liter diesel V6 units, 5.0-liter naturally aspirated and supercharged V8 petrol engines, and later a 3.0-liter supercharged V6 in some markets. Long-wheelbase versions emphasized rear passenger comfort, while XJR models focused on high-speed performance.

In user reviews, the Jaguar XJ is often described as a luxury sedan with more personality than many of its German rivals. Owners admire its elegant cabin, light aluminium feel, strong engines and relaxed motorway character. The diesel versions are valued for long-range efficiency, while supercharged models are praised for effortless pace. Complaints usually involve expensive suspension and electrical repairs, costly maintenance, limited dealer support in some regions and technology that aged faster than the car’s design.
