Porsche introduced its Cayenne sport utility vehicle in early 2003. Like the stimulating pepper of the same name, this luxury midsize SUV ranks as a hot number. All Cayennes have permanent all-wheel drive, an inter-axle differential lock and switch-activated Low-range gearing. The Porsche Stability Management system is standard. Volkswagen markets a related Touareg SUV. Even though the Cayenne's styling is distinctive, its front end is reminiscent of the automaker's 911 sports car. Like the 911, the Cayenne exhibits what Porsche calls taut lines and tight curves that communicate a feeling of elegance and speed. Seating for up to five people on leather seating surfaces is standard; full leather seats are available. Front and rear parking assistance is included. Cargo capacity totals 19.1 cubic feet and expands to 62.5 cubic feet when the backseat is folded. Seat-mounted side-impact airbags and side curtain-type airbags are standard
