2006 Porsche Cayenne Turbo AWD

The four-door, all-wheel-drive Porsche Cayenne Turbo SUV was powered by a turbocharged 4.5-liter V8 that produced 450 horsepower. It was linked to a six-speed Tiptronic S automatic transmission, which was standard. The Tiptronic was equipped with a gate that enabled the driver to shift manually, depending on driving conditions.
Standard features for the Cayenne Turbo included power windows, 12-way adjustable power front seats, a multifunction steering wheel with audio controls, Porsche's Park Assist system, heated windshield wiper nozzles, a multifunction trip computer, a central locking system with remote, heat insulating laminated glass, a 14-speaker Bose stereo system, 18-inch Cayenne Turbo wheels, an air suspension system, Bi-Xenon headlights, an anti-theft system, and a Porsche Communications Management system with DVD navigation and an MP3-compatible CD radio.
Options included a four-zone air conditioning system, a CD changer, a sport tailpipe, a SportDesign Kit, and an Offroad Design Package.
