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 22 - 23 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.

Against its main alternatives, such as the Mercedes-Benz SL and BMW M6, the XKR is attractively priced and you get plenty of standard equipment including sat nav. It’s not cheap to run, insurance is the maximum group 20 and Jaguar servicing is notoriously pricey (although you should get impeccable customer service). Fuel economy isn’t great either with an average of just 22mpg – but few cars that offer this performance manage much better.

As you’d expect, the Jaguar is no eco-friendly model. It emits 294g/km of CO2 and averages just 22mpg. The later 5.0-litre V8 is fractionally better – emitting 292g/km of CO2 and returning 23mpg.

No major problems have yet come to light and owners have yet to report any significant defects. However a few of the early convertible XK models we tested had erratic window controls. But Jaguar continues to score highly in customer satisfaction surveys both in the UK and the US.
