The JAGUAR XJ (2015-21) 4DR SALOON 5.0 V8 SS 550 EU6 XJR AUTO8 is a full-size luxury saloon near the top of the UK executive-car market. Its elegant shape and spacious cabin make it a distinctive alternative to the Mercedes-Benz S-Class, BMW 7 Series and Audi A8 for luxury buyers. The XJR’s supercharged 5.0-litre V8 delivers 550 horsepower, bringing dramatic acceleration to a comfortable, chauffeur-friendly saloon. It suits experienced drivers wanting a refined long-distance car or an impressive business vehicle; expect higher fuel and ownership costs than with less powerful alternatives, while the quiet cabin makes motorway travel particularly relaxing.
