Probably the new venture with Toyota MC has something to do with this. Toyota is a giant when it comes to electric vehicles (i.e. Prius). It will be a lot easy to adopt a lot of the technology that's already working and tailor it to suit the BMW cars. Maybe the facility in France and the resources will be used to tailor Toyota technology for BMW cars. This is just a thought.
