Jaguar XJS: The Grand Tourer That Redefined British Luxury
Share
Some cars are built to get you from A to B. The Jaguar XJS was built to make you forget you ever had a destination. Long, low and impossibly elegant, it arrived in 1975 as a car that rewrote the rulebook for grand touring, and in two decades of production it never stopped turning heads. It is, quite simply, one of the finest things Britain ever put on four wheels.
More than that, it carries a story. The XJS was born out of ambition, shaped by adversity, and loved by a generation who understood that a car could be a work of art as much as a machine. That combination of beauty and brutality is exactly what makes it endure.
Origins and History
The XJS arrived in October 1975 as the successor to the legendary E-Type, a car widely regarded as one of the most beautiful ever made. Filling those shoes was never going to be easy, and Jaguar knew it. The brief was simple on paper: produce a high-speed grand tourer capable of crossing continents in supreme comfort, with a V12 engine and the kind of refinement that Bentley and Mercedes charged twice the price to deliver.
Chief engineer Bob Knight led the project, with styling handled in-house at Jaguar's Browns Lane facility in Coventry. The car launched at the height of the 1970s fuel crisis, which did it no favours commercially. Critics were divided. Some mourned the loss of the E-Type's raw sportiness. Others recognised the XJS for what it was: a different kind of Jaguar, calmer and more civilised, but no less thrilling on its own terms.
Production ran until 1996, covering three distinct generations and a remarkable 115,000 cars. The HE (High Efficiency) engine upgrade arrived in 1981, slashing fuel consumption and transforming the XJS from oil crisis pariah to genuine long-distance companion. A full facelift in 1991 modernised the bodywork and introduced a new 4.0-litre straight-six variant. By the time the final car rolled off the line, the XJS had outlasted almost every rival it started alongside.
The Design
Love it or loathe it, the XJS is instantly recognisable. Designer Malcolm Sayer began the project before his death in 1970, with the work completed by Doug Thorpe and the Jaguar styling team. The result was a car with a profile unlike anything else on the road: a long, flat bonnet, steeply raked windscreen, and a roofline that tapered elegantly into those distinctive flying buttresses at the rear. Those buttresses attracted more debate than almost any other styling element of the decade.
Early criticism faded over time. The XJS aged in the way that genuinely good design always does, becoming more distinguished with every passing year. The 1991 facelift softened the front end and removed the original's rubber bumper inserts, producing a cleaner, more cohesive shape. In convertible form, with the hood lowered and the sun catching the bonnet, it is breathtaking.
The interior matched the exterior in ambition. Sumptuous Connolly leather, burr walnut veneer across the dashboard, and a driving position that wrapped you in comfort without ever feeling disconnected. Jaguar understood that luxury was not just about materials, it was about atmosphere, and the XJS had it by the bucketful.
Performance and Driving
Under that long bonnet sat Jaguar's 5.3-litre V12, a unit so smooth that engineers had to fit an artificial idle note to remind drivers it was running. In standard tune it produced around 285 horsepower, enough for a 0-60 time of 7.6 seconds and a top speed of 153mph. Those figures look modest by modern standards, but the way the power arrived, in one long, uninterrupted surge with almost no vibration, was something entirely its own.
The HE engine, developed using combustion technology from Swiss engineer Michael May, transformed the unit. Fuel consumption dropped by nearly 20 percent and throttle response sharpened noticeably. The later 6.0-litre V12 fitted from 1993 added another 25 horsepower and improved torque across the range, turning the XJS into something genuinely quick by any era's measure.
The four-litre straight-six introduced in 1983 and revised significantly in 1991 is the XJS that most buyers encounter today. It is lighter, more responsive and cheaper to run, and in the later AJ6 form it is considered one of Jaguar's finest engines. Less theatrical than the V12 but deeply satisfying, it suits the car's character perfectly.
Cultural Impact
The XJS became a cultural landmark almost in spite of itself. It was the car of choice for a generation of British executives and entertainers, appearing in countless television series and films throughout the 1970s and 1980s. Its profile became shorthand for a particular kind of effortless cool, British, fast and slightly dangerous.
Perhaps the greatest testament to the XJS is how it has been embraced by a new generation of enthusiasts. Prices climbed steadily through the 2010s as buyers recognised what they had overlooked for years. The classic car market finally caught up with what Jaguar always knew: the XJS was never a compromise. It was a statement.
Buying a Jaguar XJS Today
Values have risen sharply but the XJS remains accessible by classic car standards. Clean, low-mileage V12 coupes from the early 1990s command between £15,000 and £30,000. Convertibles attract a premium, often £5,000 to £10,000 more for equivalent condition. Earlier pre-HE cars are cheaper but more demanding to run and best suited to committed enthusiasts.
The V12 requires regular coolant changes and benefits from a well-sorted cooling system, as overheating is the most common cause of expensive damage. Check for rust around the rear subframe, sills and the area beneath the rear windscreen. Electrical gremlins are common on high-mileage cars but rarely terminal. The best advice is to buy the very best example you can afford and join the XJS Owners Club before you hand over any money.
The four-litre straight-six is the more practical choice for regular use, with lower running costs and excellent parts availability. Either way, a well-maintained XJS is a genuinely usable classic capable of covering long distances in extraordinary comfort. That was always the point.
