The aluminum-bodied XJ is Jaguar's premium sedan. A 5.0L V-8 and 6-speed automatic assure excellent performance. The luxurious interior still features leather and wood veneer, but also includes features that are more contemporary. One example is the virtual instrument cluster rendered on a high-definition display. The XJ offers a 1200W Bowers & Wilkins audio system with 20 speakers. The XJL stretched wheelbase models provides additional rear legroom. The model range also includes a supercharged model for performance enthusiasts.

An all-new XJ debuts for the 2010 model year. The new model wears more contemporary styling that makes a clean break with past models. Although the wheelbase is unchanged, the new model is about an inch longer than the old model. Like other Jaguars models for 2010, the XJ equips a new 5.0L V8 engine. Depending on the application, the output of the engine ranges from 385-bhp to 510-bhp. The XJ continues to offer XJL long wheelbase models.
