Porsche currently builds some of its Boxster sports cars at a Volkswagen plant in Osnabrück, Germany. The former Karmann plant has been helping Porsche build the Boxsters because capacity at Porsche’s main plant in Zuffenhausen, the official home of the Boxster, is at the limit and demand for the cars remains strong.

However, Porsche is investing more than $500 million to expand the Zuffenhausen plant so that in future all of the automaker’s sports car models can be built there. Most of the investment will go into funding a new body shop.

"All two-door Porsche models will come from Zuffenhausen in the future," Uwe Hueck, the head of Porsche's works council, told Automotive News (subscription required).

The Zuffenhausen plant already builds the Boxster and Cayman as well as the 911 and 918 Spyder. The expansion of the plant should be complete by 2016, meaning no more Boxsters will be built at the Osnabrück plant beyond that date. That date is also when we're expecting to see a facelifted version of the Boxster introduced.

The upgrades to the Zuffenhausen plant come as Porsche prepares a new modular sports car platform that will eventually underpin its replacements for the Boxster, Cayman and 911 models and possibly a new 960 supercar to rival the likes of the Ferrari 458 Italia, Lamborghini Huracán and McLaren 650S.
