The Porsche Cayenne Turbo was a performance-focused variant of the 958.1 Cayenne that was introduced for the 2011 model year (late 2010 in Europe). The 958.1 Turbo was powered by a twin-turbocharged 4.8L V8 engine that generated 493hp and 516 lb ft of torque that was sent to all four wheels via an 8 speed automatic transmission. In addition to its powerful engine, the Turbo was given various upgrades and improvements to the suspension and drivetrain. Production of the 958.1 Cayenne Turbo ended in 2014, when it was replaced by the 958.2 Porsche Cayenne Turbo.
