Jaguar XF Diesel becomes most efficient Jag ever

November 16th, 2011 by Darren Cottingham

A British team has crossed the U.S.A, from New York to Los Angeles, in a Jaguar XF 2.2 Diesel averaging an incredible 4.49 litres/100 kms over 4,480 kms – making it the most efficient Jaguar ever built.

Finishing in Los Angeles, California, the journey – the equivalent of travelling from London to the Sahara – took in 11 states, three time zones and eight days. Yet the XF only required four stops for fuel – its peak economy of 4.21 litres/100 kms 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 2.2D. 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.’

Driven by independent testers, David and Alexander Madgwick, the XF 2.2D 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 85.2 km/h incorporating a multitude of real-life scenarios including the busy roads exiting New York and, towards the end of the trip, entering Los Angeles, road works, high winds and a climb to 2217 metres above sea level.
