Jaguar XJ Specs, Engines & Dimensions (1968–1973) — First Generation
The first-generation Jaguar XJ set the template for the British luxury sedan: a low, wide four-door built around quiet cruising, supple suspension and effortless pace rather than outright sporting aggression.
Every Jaguar XJ engine here is gasoline and drives the rear wheels, so power delivery feels smooth and relaxed. Smaller units such as the 2.8 AT suit calm daily use, the 4.2 AT adds easier overtaking, while the 5.3 MT pairs the largest displacement with a manual transmission for drivers wanting more involvement.
