GM might make a swap in its European production plans, shifting Buick assembly to Opel and Saab assembly to Sweden. Names of the models in question haven't been mentioned, but the Opel Insignia, Chinese-spec Buick Regal and coming Saab 9-5 are all built on GM's Epsilon II platform.
The original plan was to produce the Saab 9-5 in Sweden, and Saab has been studying the Trollhatten factory's viability for the task. Factory representatives at the Russelsheim plant have also been lobbying for more cars to produce, thinking the operation underutilized, and they would certainly be building more Buicks than Saabs. And if other rumors are correct, it would keep siblings that GM plans to bring closer together - Opel and Buick - under the same roof.
The swap, which would mean not building any new Saabs in Germany, would also send 9-3 production to Sweden. Sending 9-5 production there as well could also be seen as another step in extricating Saab from GM's web to assist in efforts to find a buyer for the brand.
