Porsche joins the green scene

Porsche's long-awaited hybrid system has finally been confirmed as a production runner in the German marque's upcoming Panamera model.

The new sports saloon, which will make its world debut in 2009, will be initially introduced with conventional powertrains but Porsche has announced it will be followed with a hybrid system.

It will utilise components of the Cayenne hybrid, which is set to go on sale at the end of this decade. Porsche says the Panamera Gran Turismo is expected to average about 9.0 litres per 100km and can be driven in different modes, disengaging either the combustion engine or electric motor or combining both.

The battery unit will be in the rear luggage compartment, while the hybrid module and power electronics will sit between the engine and transmission, with an additional clutch and the electric motor.

It will be the fourth model series for Porsche and has roomy interior and muscular, sporty looks. The four-door will also have two single seats in the rear.
