STUTTGART, Germany —Porsche has released images of the production 2010 Porsche Panamera four-door sport sedan, several months ahead of the car's official launch. Unlike the early video of the car our spy shooters caught on the Nürburgring, these photos show the new Panamera in its 'final look' form, according to Porsche. The company describes it as a 'unique interpretation of the classic saloon body.'The Panamera is lower and wider than a traditional four-door at 76.0 inches wide and 55.8 inches high. In front, there are contoured air intakes in place of a traditional grille. The 911 resemblance is strongest in the wheel arches and long hood line, Porsche notes.The Panamera will be available with engine choices ranging from 300 to 500 horsepower, including a hybrid version. Engines will be mated to a manual six-speed or Porsche's new PDK seven-speed, automated dual-clutch transmission. The top model will have all-wheel drive as standard; it's an option on other Panameras. Full powertrain information won't be out till spring, Porsche says.The 2010 Porsche Panamera is set for official unveiling in the spring, with an on-sale date by the end of summer 2009.Inside Line says: We're almost positive the Panamera will drive better than it looks. — Laura Sky Brown, Correspondent
