Well, it’s finally here: Porsche reveals their new 4 door Panamera. The Porsche Panamera is a four-door, four-seat luxury sedan, currently in design stage, set to be launched in 2009. It will be front-engined and rear wheel drive.

At launch, the Panamera will have three engine choices - a 3.6 L V6 found in the 2008 facelifted Cayenne with 300 hp (224 kW/304 PS) in the base Panamera, a 4.8 L V8 with 405 hp (302 kW/411 PS) in the Panamera S, and a turbocharged 4.8 L V8 with approximately 500 hp (373 kW/507 PS) in the Panamera Turbo. There is even a hybrid version in the pipeline.

Rumors suggest that the V-10 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 V-10 engines per year. A rumor is also around that the V-12 diesel from the Audi Q7 could make it into the Panamera.

Stay tuned for more information.
