Jaguar XF travels 816 miles on a single tank

New 2.2-litre diesel XF travels from Birmingham to Munich on one tank of fuel

Jaguar XF travels 816 miles on a single tank

28th June 2011

Jaguar has just released its most efficient model yet – the 2.2-litre diesel XF – and to prove its worth the British firm has completed an 816-mile road-trip on one tank of fuel. 

Driven by independent testers the XF traveled from Birmingham to Munich, whilst consuming just 64-litres of diesel – that makes for an average economy figure of 57mpg. By comparison, the official combined figure stands at 52.3mpg.

Andy Whyman, Chief Programme Engineer for the XF 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.”

Engineers have fitted the 187bhp engine with a Stop-Start system and an eight-speed automatic gearbox which helps to achieve the impressive economy figures – despite the brisk 0-62mph time of 8.5 seconds. 

You can read our first drive of the new XF 2.2D here.

Captain Slow?

So what was the average speed for this trip and at what time of the day were they travelling? Can make a big difference.

err they travelled 816 miles...

... I would guess they were travelling pretty much all times of the day (or most hours of the day) most cars are tested for a combined figures at 50 mph, so I would guess that was the average speed :)

XF

high averages NPG are easy to get!
What sort of speeds were they driving at???

How far?!

Makes you proud to be British.

Sounds good, let's be positive about this

Basically to get from Birmingham to Munich you are going to have to negotiate through the South East of England and will hit some form of congestion, I doubt an independent tester is going to compromise their credibility by driving overnight when there is hardly anything else on the roads!

Why be so skeptical ? We British have some of the world's best Engineers. An Engine doesn't need to be designed in Germany or Japan to be efficient !

possible

what you have to remember is that diesel is quite efficient - - only problem is that the power curve is very narrow. This is why the semi trucks have 15 to 18 speed gear boxes. This is to help keep the engine in the center of its power band, the place where the engine is most efficient - - - - gas engines the more gears help also. but the power band is quite wide so not as important as with diesel

Note it comes with an 8 speed transmission.

I drive a full size Buick la saber - and on the highway have received - 38 mpg. that is right - - - and that was at 65 to 70 mph. friends in smaller cars are going - - they do not get that good of gas mileage. - - - - - it is the design of the car, the quality of the parts - - - top of the line low friction bearings etc.

all engines have a sweet spot where the efficiency is the best, more gears means more time in that sweet spot.

Brake-Regeneration ... where ie it?

Every now and then I post a comment about this issue. Jag are trying to improve fuel economy, essential in today's climate and against class German opposition. While cars from the likes of BMW, Mercedes and Audi have commonly have had it for some time on many models there is still nothing from Jaguar, despite the XF 2.2D being their long-awaited first product brought to market with Stop-Start. Surely the car should have both stop-start AND brake regeneration as standard, to which add hybrid technology at the at the arliest convenience?
