The Porsche Panamera GT is fourth model series that will join the 911, Boxster/Cayman and Cayenne. The photos released by Porsche show that the new Panamera GT (Gran Turismo) has four doors and four seats and looks similar its sibglings with a similar face and headlamps.

Porsche has released the teaser image and begun an advertising campaign for the sports sedan which includes the launch of the Panamera Online Magazine at porsche.com/panamera. The next phase of the advertising campaign will be on 20th October with double page ads in leading news and business magazines, again offering a sneak preview of the Panamera GT.

Porsche’s Panamera sedan is expected to enter the market in early 2009 where it will be offered initially with naturally aspirated and turbocharged V8 engines followed by a smaller V6 gasoline unit. In late 2010 – early 2011, Porsche will also introduce the Panamera Hybrid featuring a full hybrid design where the hybrid module (clutch and electric motor) is positioned between the combustion engine (presumably a V6 unit) and the transmission, while the battery pack will be located in the luggage compartment. The parallel hybrid system will allow the Panamera to operate with the gasoline engine, the electric motor or a combination of both.
