The Cayenne is a luxury, midsized, unibody SUV.
Developed with the Volkswagen Touareg, it comes with a choice of a Volkswagen-based V6 engine, a Porsche V8, or a twin-turbo version of the V8.
The Turbo S comes with an even more powerful turbo V8.
Low-range gearing and advanced electronics promise some off-road capability.
The S and Turbo are very fast but lack the trademark agility of a Porsche.
