A Jaguar car has completed a ground breaking trip across North America, taking in three time zones and 11 states in just eight days.
The jaguar was driven by a British team that started in New York and finished in Los Angeles but only stopped for fuel four times, which now means the model is the most efficient in Jaguar history.
The team did not need to use theirbreakdown cover as the XF 2.2 diesel averaged an amazing 62.9 mpg over 2,884-miles; the car's peak economy of 67 mpg was reached on the seventh day of the drive.
Paul Alcock, XF project manager for Jaguar Cars, said: "This project was designed primarily to test the potential economy of the XF 2.2. The incredible figures achieved by the car were accomplished through making every element of the new XF as efficient as possible - from its aerodynamics to its four-cylinder 2.2-litre diesel engine linked to an eight-speed gearbox.
"The whole XF team is incredibly proud of what's been achieved and it's a graphic demonstration of the strength, engineering integrity and efficiency of the car."
