Jaguar XF travels 800 miles on one tank

Using the new 2.2-litre diesel engine, which will be available from September in the UK, the luxury saloon recorded fuel economy figures of 57mpg for the journey after it used just 64-litres of fuel.

Designed to showcase what is set to be the most efficient engine in the Jaguar XF line-up, the journey across Europe took in four countries and different types of road to add a dose of realism to the task.

Andy Whyman, Chief Programme Engineer for the XF, who met the car when it arrived in Munich, said: "The entire development team is very proud of what the new XF 2.2 has achieved – this not only proves the efficiency of the new model but underlines that performance and economy can be combined."

Jaguar has designed the 2.2-litre diesel engine with efficiency in mind. The engine is matched to a new, more efficient eight-speed ZF automatic gearbox and includes Stop-Start technology to reduce the amount of fuel used in heavy traffic.

The official fuel economy figure is 52.3mpg and this is matched to low CO2 emissions of 149g/km – or £125 per year in VED in the UK – to offer an alternative to BMW’s most efficient saloon, the 520d.

Alongside the environmental performance, Jaguar has quoted a 0-60mph time in eight seconds from the 190PS engine.

The new 2012 Jaguar XF will be offered with the new engine from September and the latest models will also boast upgrade to the interior materials, level of equipment and the design of the car.

Expected to cost around the £30,000 mark, the new Jaguar XF 2.2-litre diesel will join the more powerful 3.0-litre V6 diesel, a high powered 3.0-litre diesel S and a 5.0-litre V8 petrol engine in the XF line up when it goes on sale.
