Porsche Panamera

Porsche has officially confirmed it'll build a four-seat, four-door sport coupe for the 2009 calendar year (2010 model year). To be called Panamera (supposedly for the Carrera Panamericana race), it'll become the fourth car in Porsche's lineup (911, Cayenne, Boxster/ Cayman) and will not share its platform or development with any other carmaker.

Its V-8 engines are from the Cayenne, the 340-horsepower naturally aspirated and 450-horse, 4.5-liter twin-turbo, although Porsche certainly has the capability to raise the power for each by the 2010 model year. Porsche's Leipzig factory will build the front-engine, rear-drive Panamera alongside the Cayenne SUV and the Carrera GT supercar.
