Porsche has unleashed its latest 911 Turbo model which features 3.6 litre flat six turbocharged engine with a variable turbine geometry (VTG) that produces 480 hp and 66,1 kgm (or 480 lb ft) of torque.

This technology featured in turbocharged diesels since the '90s ensures a significant improvement of engine flexibility and acceleration particularly at low engine speeds. So far, however, much higher exhaust gas temperature of up to 1000° C in comparison with the turbocharged diesel has always proved to be an insurmountable barrier. But now Porsche has solved this problem in close cooperation with Borg Warner Turbo Systems by using high temperature-resistant materials from space technology wherever required.

The core features of the VTG system are the variable turbine blades guiding the flow of exhaust gas from the engine in exactly the direction required on to the turbine wheel of the exhaust gas turbocharger. The principle of variable turbine geometry thus combines the benefits of a small and large exhaust gas turbocharger all in one – a combination ensuring both very good response and high torque at low engine speeds as well as superior output and high performance at high speeds. And the supreme level of torque is now maintained consistently throughout a much wider speed range.

The 911 Turbo will be offered with two gearboxes, Tiptronic Auto & manual. According to Porsche, 0-100 km/h (62 mph) comes in 3.7 sec for the Tiptronic model and 3.9 for the Manual models while both reach a top speed of 315 km/h or 192 mph.
