According to an unconfirmed source close to the Saab and BMW discussions, both automakers have come to an agreement in which BMW will supply engines to Saab. Saab is said to be purchasing BMW engines to use in their upcoming 2012 9-3 model.

Officially both companies have not announced or confirmed anything, but the source says that news of the pact will be announced on the 29th of September, which is just before the Paris Motor Show.

According to a statement by Spyker, parent company of Saab, they confirm “that talks are ongoing and will give further details once a final agreement has been reached”. Spokesmen for BMW and Saab both declined to comment. Obviously hot on everyone’s lips is Saab’s new MINI rivaling 9-2 model.

According to the same source, they have been allowed to use the Mini Countryman’s platform for the new Saab car. Along with this, they are in talks about buying BMW’s refined diesels. There is also word that Saab plans to tap into BMW’s Efficient Dynamics initiative.

We’ve only got a few days to wait to confirm the legitimacy of these claims, but if you think about it, it does save a lot off your R&D budget by just buying engines from a reliable source. Who better to buy it from than BMW? We will keep you updated as and when we hear something substantial.
