Jaguar XJ Saloon (10 on) - Review

There are three engine choices and all are available in the standard or long wheelbase models. By far the most popular is the twin turbocharged, 3.0-litre V6 diesel - as found in the Range Rover Sport - and this 275bhp engine is superbly refined and near silent at cruising speeds. It has impressive low down punch for effortless overtaking and relaxed high-speed travel. It covers the 0-62mph dash in 6.4 seconds but it’s the mid-range acceleration that truly impresses and it will push on from 50-70mph in a mere 3.0 seconds. However, it’s also economical and can average 40mpg. For more power there’s the 5.0-litre V8 with 385bhp. This non-turbocharged engine has a smooth and predictable power delivery, accelerating from 0-62mph in 5.7 seconds with an average fuel economy of 25mpg. The range-topping Supersport model uses the same 5.0-litre engine but fitted with a supercharger. This boosts maximum power to 510bhp and brings the 0-62mph time down to just 4.9 seconds. At a sedate pace it’s happy to silently purr away, but push the accelerator and it surges into life with an intoxicating turn of pace and a wonderful roar from the twin exhaust pipes. It feels lightning fast and yet is never intimidating or brutal. However, fuel economy does suffer with an average of just 23mpg. All models come with a smooth six-speed automatic gearbox which has a standard drive mode as well as a sport setting. There are also steering wheel mounted paddleshifts, allowing you to change gear yourself.

The sheer length of the XJ means it has a considerable turning circle, but as you'd expect of such a large vehicle, rear parking sensors come as standard (Premium Luxury models also get front parking sensors) and they're pretty vital as it's not easy to judge the nose or the tail. But despite its considerable size, the XJ feels amazingly agile and nimble on the road, helped by the low kerb weight. The steering is surprisingly light and somewhat lacking in feel, but it's still incredibly responsive and precise, giving you plenty of confidence when tackling corners. Body control is exceptionally good too and at higher speeds the XJ feels planted to the road. A system called JaguarDrive Control offers different settings including winter and dynamic modes. The latter makes the throttle pedal more responsive, stiffens the suspension and sharpens the steering. Ride quality is impressive - it can feel quite firm and is often caught out by larger potholes, but there's no wallowing and it irons out uneven roads with no fuss.
