Porsche Panamera Hybrid or the international car of mystery will be the first four-door sports model to feature particularly fuel-efficient full parallel hybrid technology. At the same time the Panamera will also benefit from the experience then gained by the Porsche Cayenne as a pioneer in hybrid drive. 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. Hence, the Panamera may be driven in a number of different modes ranging from all-electric drive absolutely free of emissions all the way to the sporting style of motoring so typical of a Porsche. Stuttgart plans to reveal the Panamera to the world in 2009, initially with traditional gasoline-powered mills, with the hybrid to go on sale later.
