The Porsche Cayenne Turbo was a performance focused variant of the 957 Cayenne. Debuting for the 2008 model year, the 957 Turbo featured a range of upgrades and improvements such as larger brakes, a locking differential, and uprated adjustable suspension. The most notable feature was the 4.8L twin-turbo V8 engine, which generated 493hp and 516 lb ft of torque. This power was sent through a 6 speed automatic gearbox to all four wheels. Production of the 957 Porsche Cayenne Turbo ended in 2010 when Porsche introduced the Second Generation Porsche Cayenne.
