Jaguar XJS Specs, Engines & Dimensions (1975–1981) — First Generation
The first-generation Jaguar XJS arrived as a long-legged grand tourer rather than a sports car, pairing a low coupe body with the refinement and effortless cruising pace Jaguar built its reputation on.
The defining Jaguar XJS engine is the 5.3-litre gasoline V12, offered here in 5.3 AT and 5.3 MT coupe forms. Both send power rearward, so the drivetrain favours smooth torque over revs; the automatic suits relaxed touring, while the manual gives the driver more direct control.
