Jaguar XJS Specs

Every Jaguar XJS generation, measured

One row per generation. Watch the weight column — that is where most of the change happens for the Jaguar XJS, 489 lb of it since 1971, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.

From 1971 to today the XJS gained 11.8″ of length (6%) and 489 lb of weight (14%). A modern compact often outweighs the mid-size car of a generation before.

XJS year by year

Measured every model year, not just at generation changes — 27 years on record for the Jaguar XJS. Small moves inside a generation are facelifts; the jumps are the 6 new platforms below.

Will a XJS fit

The practical question behind every dimensions search, and for a 16.8-foot Jaguar XJS it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the XJS clears the garage by 2.2 ft. We allow a foot of clearance in both — nobody parks to the millimetre.

Against cars of the same length

Compared with 645 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.

A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 3,885 lb the Jaguar XJS is 370 lb lighter than typical for its size, which generally shows up as fuel economy and stopping distance.

How we measure

Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 27 measured model years for the Jaguar XJS between 1971 and 2020.

One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Jaguar XJS fits into 6 rows instead of 27. Where a generation offered several body styles, the figures are the base measurements for that generation of the Jaguar XJS.
