When in 1998 Porsche announced it was going to build an SUV, the proclamation was greeted with scoffs and pure horror. How could Porsche turn its back on its heritage by introducing a lumbering sport utility vehicle, many asked. But days after the vehicle, called Cayenne, came to market in 2002, it was clearly a success. It didn't so much change Porsche's basic character as extend it, because the Cayenne quickly became renowned as the sports car of the SUV set – a vehicle with off-road credentials that was also a fulfilling to drive. Never one to rest on its laurels, Porsche adds an even more dynamic element to the Cayenne line in the form of a new Turbo S model.
