Jaguar’s XF 2.2 diesel which left New York eight days ago has completed its 2884 mile run to Los Angeles averaging 52.3 (US) mpg, making it the most efficient Jaguar yet. I can believe this as my previous generation Jaguar diesel wagon would regularly return 41 (US) mpg on freeway hauls, and that was with only a six-speed manual and not the eight-speed auto this XF is equipped with.
The journey took in 11 states, three time zones and eight days. Yet the XF only required four stops for fuel – its peak economy of 55.7 (US) mpg being achieved on the penultimate day of the trip.
Paul Alcock, XF project manager, Jaguar Cars, who was present throughout the journey, commented: “This project was designed primarily to test the potential economy of the XF 2.2. The 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-liter diesel engine linked to an eight-speed gearbox. It’s a graphic demonstration of the strength, engineering integrity and efficiency of the car.”
Driven by independent testers, David and Alexander Madgwick, the XF 2.2 was a standard UK registered, right-hand drive vehicle. In the course of the coast to coast adventure, the car maintained an average speed of 53 mph incorporating a multitude of real-life scenarios including the busy roads exiting New York and, towards the end of the trip, entering Los Angeles, as well as encountering road work, high winds and a climb to 7,275 feet above sea level.
