The Porsche Panamera is a four-door, four-seat coupe, currently still in concept stages, set to be launched in 2009. It will be front engined and rear wheel drive and powered by a modified version of the 4.5 L V8 found in the Cayenne, equipped with the FSI system invented by Volkswagen (Porsche and Volkswagen colaborated on the Cayenne/Touareg sport utility vehicle). Rumors suggest that the V10 engine from Porsche's limited-run Carrera GT supercar may be offered as well, although this is still extremely unlikely given the expense of manufacturing the engine and that Porsche does not currently have a facility capable of producing a suitable number of the V10 per year.

The final assembly of the vehicles will take place in Leipzig. Engines will be assembled in Stuttgart, and the car's painted body will come from the Volkswagen facility in Hanover, Germany.

The Panamera is generally considered to be the long-awaited fruit of their 989 concept from the late 1980s; some argue that it also presents itself as a suitable successor to the 2-doored 928, although some amount of debate surrounds this. It will be marketed as a direct competitor to automobiles such as the Mercedes-Benz CLS 55 AMG and Maserati Quattroporte and (to a lesser degree) a less expensive alternative to vehicles such the Bentley Continental GT, Ferrari 612 Scaglietti and Aston Martin Rapide. It is the first V8-engined sports car built by Porsche since 1995, when the 928 was discontinued and will be produced in the new plant at Leipzig alongside the Cayenne.
