We have new photos of the 2011 Porsche Cayenne Diesel, spied during testing in Sweden. The story inside.

Spy photographers in Sweden captured a new set of pictures featuring the next-generation Porsche Cayenne.  The auto paparazzi swarmed when the SUV pulled into a fuel station where the prototype was filled with diesel.

If that is the case, the spied SUV likely uses a 3.0-liter TDI V6 from Volkswagen that produces up to 240 PS (177 kW / 236 hp).  One thing has been made clear: the next-gen Cayenne looks very much like the photo posted to Porsche's German website, as suspected.

The new Cayenne will be sold in both conventional and hybrid models, with a total of five different power outputs available.  The Cayenne hybrid is expected to use an Audi 3.0-liter supercharged V6 producing about 333 PS (245 kW / 328 hp), and a 46 PS (34 kW / 45.5 hp) electric motor.  This makes the SUV an upmarket version of the VW Touareg Hybrid, which could become Porsche's most fuel efficient vehicle ever.  Other engines will likely include the a turbocharged 500 PS (368 kW / 493 hp) 4.8-liter V8, a naturally-aspirated 405 PS (298 kW / 399 hp) version of the same engine, a 3.6-liter V6 producing 290 PS (213 kW / 286 hp), and the diesel model mentioned earlier.

The 2011 Porsche Cayenne is expected to debut on the web this week, and in person at next week's Geneva Motor Show.
