The Cayenne is a spicy-hot mix of luxury, off-road ability, and sports-car performance—just what you would expect in a Porsche SUV. The base model has a 300-hp V-6; the S makes 420 hp, the GTS makes 440. Both have a twin-turbo V-6. A hybrid also is offered. All models feature eight-speed automatics and all-wheel drive. The Cayenne is easy to hustle around curves and is equally ready for family duty.
