Porsche will be introducing another variant of the Porsche Cayenne with a turbodiesel engine, using the 3.0 TDI V6 engine from the Audi Q7. This will bring the number of Cayenne variants up to 6, with the others being the Cayenne, Cayenne S, Cayenne GTS (shown above), the Cayenne Turbo, and the Cayenne Turbo S.
There has also been a gasoline-electric hybrid version of the Cayenne displayed late last year that uses only 9 litres per 100km, decent for a huge SUV.
The new Porsche Cayenne TDI will likely feature the most aggressively tuned up version of the 3.0 TDI V6 engine, which means 240 hp and 550 Nm of torque from as low as 1,750rpm. It will be unveiled in March 2009.
