Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 25 - 25 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Clearly Jaguar XJR running costs are going to be on the steep side. It’s powered by a 5.0-litre supercharged V8 whose drink habit would shame Oliver Reed. The official claimed average is 24.4mpg though stamp the loud pedal and that will plumb the depths of the low teens. That means a tank range of around 250 miles and a treble-figure bill to fill up an empty tank.

If you are concerned with the environment then Jaguar XJR emissions will come as a bit of shock. The CO2 output of 270g/km puts it firmly in the top road tax band M, so first year and subsequent road tax are going to the most expensive charges.

The British company has traditionally scored well in owner satisfaction surveys so Jaguar XJR reliability should prove strong.

This is a high performance car so regular servicing is essential and ensuring tyres are in good condition and at the correct pressures is important if the car’s handling limits are going to be explored.

Beyond that, the car’s parts are tried and tested and should provide a long life of trouble-free service.
