Porsche announced on Monday that it was currently developing a hybrid prototype version of its highly anticipated Panamera four-door GT. The Panamera Hybrid prototype will use the same gas-electric drive concept as Porsche’s other hybrid car, Cayenne; the company claims a 30% reduction of fuel consumption.

According to the popular car maker, the new Hybrid is to feature a parallel hybrid system that can run on both combustion and electricity, or on one of these two drive systems alone. Porsche reportedly said that "This flexibility results in benefits such as a zero emissions driving mode, fuel savings in both city and highway driving and maximum performance when desired."

The Panamera Hybrid’s battery unit will be positioned bellow the luggage compartment and its hybrid model will be found between the engine and transmission. The hybrid module, comprised of an additional clutch and electric motor, will have the ability to choose between the combustion engine and the electric motor, or to combine the both drive systems as one joint power unit.

Panamera is the German car manufacturer’s fourth model line and it is scheduled to debut in 2009. Porsche promised to redefine the GT (Gran Turismo) category through these new cars, by mixing Porsche’s traditional driving dynamics with a unique design package that will afford generous front and rear space, as well as seating comfort.
