The new, diesel Porsche Cayenne

The new, diesel Porsche Cayenne

From February 2009 Porsche will sell a car fitted with a diesel engine.

The is the Porsche in question, the decision to fit a diesel engine being made in response to buyer demand and changes to legislation throughout Europe. Powerful petrol engines are now increasingly expensive to run and purchase.

Porsche has recently acquired a large chunk of the Volkswagen Group, so it’s not exactly surprising to discover it will be using a VW engine, rather than developing its own. A 3.0-litre V6 turbodiesel producing 240bhp – identical to that found in the VW Touareg.

Slowest Porsche

The Cayenne diesel will become the slowest Porsche available when it goes on sale. But it also officially returns 30.4mpg, while emitting 244g/km CO2 - which means it fits into the second highest car tax band from April 2009. The closest a Cayenne can currently get is 21.9mpg, and 310g/km.

So that’s a massive improvement. The only problem is you can already buy a BMW X5 (or X6) diesel that’s more powerful and more efficient – if also more expensive.

Still, with this Cayenne, and the new 'PDK' automatic gearbox 911s, Boxsters, and Caymans, Porsche now has several overtly sporting vehicles that are officially capable of exceeding 30mpg. And by 2010, a Cayenne hybrid will push its SUV efficiency to over 31mpg.

The new will be priced from £40,250, including a day’s driving tuition at the new Porsche Driving Experience Centre at Silverstone.
