Porsche developed the Turbo S, the most powerful Cayenne of them all. Under the hood it hides a 4.8-liter V8 engine capable of developing 550 horsepower. From the outside, the Turbo S can be recognized by its 21-inch SportPlus alloy wheels housed within its painted wheel arches and by sports exhaust system with four tailpipes made from aluminum investment casting. All models of the Turbo S have a chassis which benefits from air suspension along with Porsche Active Suspension Management which is combined with Porsche Dynamic Chassis Control and Servotronic speed-sensitive variable power steering. The high quality character of the new Cayenne top-of-the-range Turbo S is emphasized by the standard equipment of the interior, the front sports seat with Comfort Memory Package, rear seating with individual seat contours, aluminum door panels showing the name plate together with leather upholstery in two exclusive dual-color combinations plus a leather steering wheel with padded center.
