Cayenne is Porsche's first SUV. Named for the spicy pepper, this 5-passenger, all-wheel-drive unibody wagon shares its basic design with Volkswagen's new Touareg SUV. However, Cayenne is more expensive than Touareg and has its own engines and styling. It uses a 4.5-liter V8 and a 6-speed automatic transmission with manual-shift capability via steering-wheel buttons or console lever. The S model has 340 hp, the Turbo model has 450. Cayenne's AWD system is designed for severe off-road use and has low-range gearing and a locking center differential. ABS and antiskid/traction control are standard. Optional on S and standard on the Turbo is a self-leveling air suspension with six driver-adjustable heights, including 10.7 inches of off-road clearance. Towing capacity is 7716 lb. Leather upholstery and 18-inch wheels are standard; 19s and 20s are optional. The liftgate has separate-opening glass. Included on the Turbo and optional on S are heated steering wheel and seats, steering-linked bi-xenon headlamps, navigation system, and obstacle warning.
