Porsche Panamera

German sports and luxury carmaker Porsche will invest 1bn euros (£691m; $1.2bn) developing a four-door coupe that will be on the roads by 2009.




The Panamera coupe will be Porsche's fourth base-model in production, alongside the 911, Boxster and Cayenne. An artist's rendering of the car shows a low-slung, four-door sports car with narrow side windows and flowing lines.



Unlike the Cayenne, which Porsche developed with Volkswagen AG, the Panamera's production will be a strictly Porsche product. A site for manufacturing the new model hasn't been decided upon, but Porsche said it is looking at a site in Leipzig where its Cayenne and Carrera GT models are currently produced.
