The Porsche Cayenne is a series of automobiles manufactured by the German company Porsche since 2002. It is a luxury crossover SUV and has been described as both a full-sized and a mid-sized vehicle. The first generation was known internally within Porsche as the Type 9PA (955/957) or E1. It was the first V8-engined vehicle built by Porsche since 1995, when the Porsche 928 was discontinued. It is also Porsche's first off-road variant vehicle since its Super and Junior tractors of the 1950s, and the first Porsche with four doors. Since 2014, the Cayenne has been sold alongside a smaller Porsche SUV, the Macan.
