The Cayenne is definitely a great selling car from Porsche. When it appeared on the market seven years ago the company from Zuffenhausen broke a taboo: the sports car maker was bold enough to come up with an SUV … one which would become so popular, that some 216 thousand have been sold up till now. It has been the only SUV on the market offered with only gasoline engines. Here again Porsche is breaking another taboo. This year the Cayenne will also be available with diesel power.
