Summary

Porsche has been developing turbocharged gasoline engines for road and race vehicles for more than 40 years. Many significant innovations in turbocharging technology have been realised in the development history of the 911 Turbo in particular. With its downsizing concept, this engine remains synonymous with high performance in combination with incomparable fuel efficiency among high performance cars. The basis for future engine concepts with reduced fuel consumption lies in a combination of turbocharging with a reduction in engine displacement and number of cylinders. All necessary and innovative technologies such as Variable Turbine Geometry (VTG), Direct Fuel Injection (DFI) and the variable valve timing system VarioCam Plus® are already realised in Porsche production engines and impressively demonstrate the potential of modern turbo engines. The light TiAl turbine wheel that will be implemented in the Porsche Panamera represents the latest innovation for further improvement in the throttle response.
