Porsche has released the first official photos of the four-door Panamera.

Porsche says that it is both wider and lower than comparable four-door models (measuring 1931 mm (76.0 in) in width and 1418 mm (55.8 in) in height).

The Porsche Panamera will be built at the company’s Leipzig Plant, where a production hall measuring 22,000 sq m (almost 237,000 sq ft) and a logistics centre are currently under construction. While the engines featured in the Panamera are built at the Main Porsche Plant in Zuffenhausen, the painted bodyshells will be supplied by the Volkswagen Plant in Hanover. The Leipzig Plant will then assemble the Panamera for final delivery, with an annual sales target of 20,000. Porsche is once again cooperating largely with German suppliers in the production of the Panamera, with 70 per cent of the car’s overall value being created domestically. Consequently, the Panamera is most definitely a car ‘Made in Germany’, says Porsche (its Boxster is assembled by Valmet in Finland).

The new four-door Porsche Panamera Gran Turismo will be making its world debut in spring 2009, and the first models will be arriving in Porsche Centres worldwide from late summer next year.

Porsche says it has developed superior and up-to-date power units for the Panamera. The V-engines will come with six and eight cylinders and range in power from 300 to 500 bhp. Some of the engines use turbocharger technology and Direct Fuel Injection ‘making them both fuel-efficient and powerful’. The flow of power to the wheels goes either through a manual six-speed gearbox or the Porsche seven-speed Doppelkupplungsgetriebe (PDK), or double-clutch gearbox.

A big competitor for the Panamera will be Aston Martin’s four-door Rapide, which also debuts in 2009.
