Jaguar XF makes a trip from factory to Germany on a single Tank of Diesel.

LUXURY cars and low-cost motoring are two phrases that don't usually go together - but the new Jaguar XF might just change that.

The XF, equipped with a 2.2-litre four-cylinder engine, promises to be the most efficient Jaguar yet produced.

And to prove it, Jaguar has completed an epic journey from the factory in which it was created at Castle Bromwich in Birmingham, to Munich - a distance of 816 miles - on a single tank of diesel.

The XF passed through four countries, taking in a mix of winding country roads, motorways and dense urban traffic. The XF, with just over 3,000 miles on the clock at the point of departure, consumed just 64 litres of fuel to average a remarkable 57 mpg.

Despite its keen focus on economy, the XF 2.2 produces 190 PS and 332 lb ft of torque, allowing the XF to accelerate from rest to 62mph in just 8.5 seconds before reaching a top speed of 140mph.

The XF 2.2 emits just 149g/km of CO2.
