Diesel Engine for a Porsche (Cayenne)

Despite Porsche managers claiming there will be no diesel Porsches, a big SUV without a diesel engine option is almost inappropriate nowadays. With increasing pressure from environmentalist, Porsche has put forth the Cayenne Hybrid. Additionally, with Porsche's own goal of reducing CO2 emissions by more than 20 percent by the year 2012, a diesel version is inevitable. Here are first shots of what appears to be a diesel Cayenne cold whether testing.

From the spy photographer, “I was just passing a petrol station in northern Sweden when I noticed four Porsche Cayennes standing there at a petrol station. There is nothing strange about this situation, but this time it was something that caught my eye. One of the Cayennes was driving off the diesel pump.

As all the cars left the petrol station I followed them for a while, and they stopped outside a restaurant. I noticed that one of the Cayenne's exhaust pipes were quite different. Not the usual big twin pipes, but instead a single smaller pipe on each side, and that was the Cayenne driving off the diesel pump. With no signs inside the car I decided to wait for them to finish their dinner and listen to the engine as they turned on the engine and drove off. And as suspected, I was right, that was really a diesel powered Porsche - no doubt about that.”

As previously reported, it is believed the most logical engine candidate, which is currently being developed by Audi, is a twin-turbocharged 3.2 litre V6 diesel engine producing more than 300hp.
