For those of you with a taste for performance AND a sport utility vehicle that could use some biodiesel, checkout the diesel version of the Porsche Cayenne expected in 2009. Industry analyst Peter Schmidt indicated the the primary motivation for the diesel Porsche Cayenne is the cost of fuel and improving emissions in diesel technology. The engine fitted into the Cayenne will be an Audi built 3.2 liter twin turbo V6 and Automotive News Europe states that this 300 HP SUV will return about 30 mpg. (no indication whether this vehicle will make it to North America in 2009)
