Many will cringe at the idea of a diesel-powered Porsche, but since Stuttgart rolled out its first SUV, we've all had a while to get used to the idea. Although previous speculation held on to hopes that Porsche might employ a more powerful 3.2-liter oil-burner, reports now indicate that the Cayenne diesel will employ Audi's 240-horsepower 3.0-liter TDI V6.

Expect the diesel Cayenne to debut next March, following a probable launch at the 2009 Geneva auto show.
