Saab managing director Jan Ake Jonsson and the company's entire board will be replaced with immediate effect, as part of GM's wind down process.
However, Jonsson, who joined Saab in 1973 and became MD in 2005, will remain with the company and assist restructuring firm AlixPartners with the company's closure. This process is expected to take several months.
GM has also stressed that it is still negotiating to find a buyer for Saab, and the hardline stance of chairman Ed Whitacre during the Detroit motor show is being taken as a message to potential bidders Spyker and Genii that they must improve their offers.
Saab spokeswoman Gunilla Gustavs told Automotive News: “There is still the possibility that the negotiations on the bids will result in a decision to sell Saab in its entirety.”
