The Porsche Cayenne is a series of mid-size luxury crossover sport utility vehicles manufactured by the German automaker Porsche since 2002, with North American sales beginning in 2003. It is 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 2008, all engines have featured direct injection technology.
