Fuel Economy – The 2010 Jaguar XF is equipped with one of three engines. Regardless of engine selection – 4.2-liter V-8, 5.0-liter V-8, supercharged 5.0-liter V-8 – fuel economy falls within a narrow range between 15 mpg in the city and 25 mpg on the highway, with the smallest engine the most fuel efficient and the supercharged engine the least fuel efficient.

Our review vehicle, the XF Premium with the normally-aspirated V-8, is rated 16 mpg in the city and 23 mpg on the highway. We averaged 18.7 mpg during a week of mixed driving. Combined with the XF’s 18.4-gallon fuel tank, this actual fuel economy figure results in an approximate 345-mile range between fill-ups of premium unleaded.

Safety – Neither the National Highway and Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) has crash tested the Jaguar XF, so ratings are unavailable.

Environment – According to the EPA, the 2010 Jaguar XF consumes 18 barrels of petroleum annually when equipped with the 4.2-liter or 5.0-liter V-8, and 20.1 barrels of petroleum annually when equipped with the supercharged 5.0-liter V-8. This results in carbon footprint ratings of 9.6 tons per year for the non-supercharged models, and 10.8 tons per year for the supercharged models. Air pollution scores were not available at the time this review was published.
