Porsche offers its SUV in three flavors: Cayenne, Cayenne S, and Cayenne Turbo. The Cayenne is the standard model, equipped with a V6 engine and a six-speed manual transmission. It is well equipped, blessed with the same driving dynamics as its more powerful and more expensive brethren, save outright acceleration and at-the-limit handling. The Cayenne S adds a significantly more powerful V8 engine and standard Tiptronic automatic transmission, larger wheels, bigger front brakes, and a seat memory package. Turbo models get another giant dollop of horsepower and torque, along with Porsche Active Suspension Management (PASM), red brake calipers, bi-xenon headlights, heated seats and steering wheel, DVD navigation, and a Bose audio system.
