The Jaguar XJ is very slightly cheaper than a BMW 7 Series, but around the same price as an Audi A8. A Mercedes S-Class is considerably pricier, but makes up for it with much better residuals.
The V6 diesel offers the best CO2 emissions and fuel economy figures in the XJ range. They are comparable with the equivalent S-Class and A8 engines, but all are roundly beaten by the BMW 7 Series.
Both XJ petrol engines are much more expensive to run in terms of both tax and fuel costs. The V8 is easily the most costly but the supercharged V6 isn’t that far behind.
Jaguar XJ equipment
Entry-level Luxury models are well equipped and the best value. Heated, leather seats front and rear, parking sensors, four-zone climate control and a touchscreen infotainment system with sat-nav are all standard.
Higher-spec versions simply pile on the kit by degrees with leather, larger alloy wheels, park assist and bodykits all featuring at some point.
The prime example here is the XJR. Available only with the most powerful supercharged V8, it comes with a model-specific bodykit, sports suspension, an active differential, four exhaust pipes and a 174mph speed limiter.
As ever, not only are these higher-spec versions expensive, but they also push the XJ into price bands that bring it closer to better rivals such as the Mercedes S-Class and BMW 7 Series. They also lose value much faster than the more modestly equipped, entry-level models.
Jaguar XJ reliability
Jaguar was placed a disappointing 30th out of 37 manufacturers in our latest What Car? Reliability survey. Unfortunately, we don’t have any data on the XJ itself.
Fortunately, every new Jaguar comes with a three-year, unlimited mileage warranty as standard, which can be extended at extra cost. This is better than many of the XJ’s rivals, although the BMW 7 Series enjoys an equivalent level of cover.
Jaguar XJ safety & security
Every XJ has a raft of safety equipment as standard, including emergency brake assist, a lane-departure warning system, a pedestrian-friendly pop-up bonnet and six airbags.
There’s also an optional Highway Pack, which adds blind spot monitoring, traffic sign recognition and a system that warns you if another vehicle is crossing your path while you’re reversing. An alarm and engine immobiliser helps to deter thieves.
Euro NCAP has not yet tested the XJ, so no star safety ratings are available.
