Porsche will be building a hybrid drive version of its new Panamera which will go on sale before 2010.

The hybrid prototype will offer an average fuel economy of over 31mpg. 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.

The new Panamera Gran Turismo will be making its world debut in 2009 and will be introduced initially with proven drive concepts. The hybrid version will follow later, depending on market requirements.
