Spies at Auto Express have caught the Porsche Cayenne Diesel filling up at a fuel station in Sweden. The black car was undergoing cold weather testing and caught the spies attention when the testers parked to fill up diesel. The diesel clatter later cleared their doubts and disbeliefs.

The Oil-burning version of the popular SUV has been in the company's pipeline for sometime now. Sweden is a preferred place for cold weather testing. A host of cars like the Mercedes B-Class, Chevrolet Camaro, Aston Martin Rapide and Porsche's own Cayman have been spotted testing in Sweden in the past two months alone.

Engines for this SUV will be borrowed from its cousin Touareg’s 3.0-litre V6 TDI and the V12 diesel engine, which will also find its place on the Q7 later this year.
