The Porsche Cayenne Turbo GT - Tiptronic S with shorter shift times and titanium sports exhaust system

The biturbo engine in the Cayenne Turbo GT is currently Porsche's most powerful eight-cylinder unit. The most extensive optimizations have been made to the crankshaft drive, turbocharging, gasoline direct injection, intake and intercooling. Inside the engine, the Turbo GT's V8 differs from the Turbo Coupé in basic elements such as the crankshaft, connecting rods, pistons, timing chain drive and torsional vibration dampers. In view of the increased power output to 471 kW, CO2 emission combined 264 g/km (NEDC)), these components are designed for higher peak loads and improved driving dynamics. The eight-speed Tiptronic S with shorter shift times and Porsche Traction Management (PTM) have also been adapted. The latter has an additional water cooling system for the transfer case. The standard sports exhaust system with centrally positioned tailpipes is a special design for the Cayenne Turbo GT. From the center of the vehicle, the exhaust tract including the rear silencers is made of lightweight and particularly heat-resistant titanium. An additional weight saving is achieved by omitting the center silencer.
