Several models are offered: Base, S, GTS, Turbo, Turbo S and S E-Hybrid. Additionally, Platinum Editions are offered for Base and S E-Hybrids. Base Cayennes feature a 3.6L V6 that puts out 300 horsepower. The S and GTS use a 3.6L V6 twin turbo that churns out 420 horsepower in S form and 440 horsepower in the GTS. The Turbo version utilizes a 4.8L V8, also with two turbochargers, allowing it to produce 520 horsepower, while the Turbo S bumps the output up to 570 horsepower. Porsche claims 0-60 mph from the Turbo S in just 3.8 seconds, with a top speed of 176 mph. Finally, the S E-Hybrid employs a 333-horsepower supercharged 3.0L V6 and a 47-horsepower battery-powered electric motor that combine to deliver 380 horsepower. The Cayenne Hybrid can run on either one or both of its powerplants for an even blend of power and fuel efficiency. Interiors exhibit a typically Porsche attention to detail; they look, feel and fall in line with what one would see in the Panamera sedan. All rear seats are split-folding. Cayennes are suspended by a double wishbone setup in the front and a multilink rear axle, with front and rear stabilizers. All Cayennes offer all-wheel drive via an 8-speed Tiptronic S automatic, which is standard on all trims.
