The Cayenne combines the versatility and cargo space of an SUV with the sportiness of the Porsche brand. An abundance of muscular curves and a forward-leaning rear window convey the Cayenne's purpose of speed, even while standing still. Inside, the cabin's finely stitched leather and overlays of wood and metal are uniquely Porsche. Notable features include all-wheel drive, 8-speed automatic transmission, a height-adjustable power liftgate, and a 10-speaker audio system with a 7-inch touch screen. Safety comes in the form of six airbags, a full suite of electronic stability aids, and a torque-vectoring system that assists when cornering.
