The Porsche Cayenne is a mid-size luxury crossover sport utility vehicle produced by the German manufacturer 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.
The Porsche Cayenne entered the market with mixed anticipation. However, it soon proved that it was the performance vehicle among SUVs and was praised for its excellent handling and powerful engines. The lineup initially consisted of the V8-powered Cayenne S and Cayenne Turbo. Later in the model cycle, VR6 and diesel-powered versions joined the lineup.
The S is powered by an 8-cylinder engine with a dry-sump lubrication system and variable valve timing. It produces 340 PS (250 kW; 335 hp) and 310 lb ft (420 N m) of torque. Acceleration from 0–60 mph (97 km/h) takes 7.1 seconds and the top speed is 150 mph (241 km/h).
The GTS is powered with a 405 PS (298 kW; 399 hp) 4.8 L V8 and features a sport suspension and 21-inch (533 mm) wheels. It is lighter than the Cayenne S and has an aerodynamic body kit. The Porsche Cayenne GTS has a 0–100 km/h (62 mph) time of 5.7 seconds. A six-speed manual transmission is also offered.
Porsche has sold a diesel version of the Cayenne, powered by a 3.0-L V6 VW TDI engine, since February 2009. The engine is rated at 240 PS (177 kW; 237 hp) and 550 N m (410 lb ft) of torque. The car was unveiled at the 2009 Geneva Motor Show. The diesel can accelerate from 0–60 mph (97 km/h) in 9.2 seconds.
The Cayenne S Transsyberia was originally a racing vehicle for Transsyberia rally, only 26 were built.
The street version was later built to commemorate Porsche's victory in Transsyberia rally. It is a variant with the 405 hp (302 kW) direct-inject 4.8-L V8 from the Cayenne GTS. Sales began in January 2009, with a production run of 600 road vehicles.
