The museum, which was supposed to get rolling in 2007, will probably not be finished until the end of 2008, Porsche AG said on Wednesday in Stuttgart. However, the company did not name an exact date.
Porsche spokesperson Anton Hunger also said the €50 million the company had planned on spending would not be enough to cover construction costs. "The numbers will likely be on the higher end of double-digit millions," he said.
Some eighty Porsche models will be housed in the 5,600-square metre museum inside a futuristic exterior. The carmaker's old museum building only held 20 models.
