Porsche will build a hybrid version of its new four-door Panamera with an average fuel economy of over 31mpg.
The carmaker announced it will use the components already showcased in the Cayenne Hybrid prototype and will enter the market by the end of the decade.
The Panamera will be the first four-door sports model to feature ‘full parallel’ hybrid technology.
The system will consist primarily of the battery unit positioned in the luggage compartment, the power electronics, and the hybrid module between the engine and transmission comprising an additional clutch and the electric motor.
Depending on driving conditions, the hybrid module is able to disengage either the combustion engine or the electric motor, or to combine both drive systems as one joint power unit.
This means the Panamera can be driven in a number of different modes ranging from an emission-free all-electric drive to full sports mode using just the combustion engine.
Inside the Panamera will be just four seats, with two single chairs in the back.
However the company claims there will be a large amount of rear had and leg room.
The new Panamera Gran Turismo will be making its world debut in 2009 as a petrol model, with the hybrid expected a year later.
