There are currently 3 engines available; A 3.2 litre V6 engine from Volkswagen, a 4.5 litre V8 engine, and a 4.5 litre V8 which is turbocharged. The turbocharged model has an extremely high performance for an SUV -the turbocharged model is faster than the company's Boxster S. Reviews indicate that the Cayenne handles remarkably well for a heavy SUV - far better than its nearest competitor, the BMW X5, whilst having a comfortable ride. The competence however comes at a cost, with the standard model considerably more expensive than a comparably-specified BMW X5 and the Turbo model costing a similar amount to a Mercedes S-Class limousine.
In standard trim, it is unsuitable for severe off-road conditions, as the low-profile tyres with thin sidewalls required to give it acceptable on-road handling are highly vulnerable to punctures by rocks and stakes.
Many Porsche enthusiasts are unhappy with the company for producing an SUV, seeing it as diluting the meaning of the brand. According to Wheels magazine, a well-regarded Australian car magazine, the decision to develop the Cayenne was a contentious one for the company for this reason. Management reportedly felt, however, that the company needed a more dependable source of revenue than the fickle sports car market.
