Trust us here; the much humbugged diesel era has arrived in Stuttgart and this 2010 Porsche Cayenne Diesel 3.0 TDI rips it up in worthy style. This is far more than some nasty farm implement dressed up with a Porsche crest.
Lord knows what sort of CO2 emissions rating the old Porsche tractors inflicted on Mother Earth, but the V6 TDI engine has the very latest piezo units for the common-rail direct injection, clever exhaust gas recirculation and a standard diesel particulate filter, so it emits 21 percent less CO2 than the Cayenne’s 3.6-liter gasoline V6 and improves mpg by 39 percent. The Cayenne diesel jumps to 100 km/h (62 mph) from a standstill in just 8.3 seconds, only 0.2 second slower than the gas V6, and this is mainly due to the diesel’s added 154 pounds at the curb (4,939 pounds in total).
