Porsche to Offer a Hybrid Version of its Four-Door Panamera

Porsche AG announced in early January that it will develop a hybrid version of its upcoming four-door Panamera. The Porsche Panamera hybrid will position an additional clutch and electric motor between the engine and the transmission, allowing the hybrid system to disengage either the engine or the motor, or to engage both at once. According to Porsche, the hybrid system should allow the vehicle to achieve a fuel economy of about 26 miles per gallon, consuming 30% less fuel than the standard Panamera. The Panamera will make its world debut next year, but the hybrid version will have to wait until some future, unspecified date. See the Porsche press releases from January 7 and January 8.
