GM is seeking collaboration with BMW on gasoline and diesel engines, according to a report in Der SPIEGEL magazine.

GM and BMW have not yet confirmed any details on this collaboration.

Stephen Girsky, GM board member in charge of strategy has asked BMW to start discussion on “far-reaching joint projects”, Der Spiegel said, without citing any source.

The article also says that BMW’s Cheif Executive, Norbert Reithofer stated previously that BMW is interesting in selling engines to other companies, as long as this would not give the competitor an edge over it, or spoil BMW’s image.
