Looks and sounds a lot like the DW Link or VPP already in use in MTB

Only similarity is in the fact that they both use two-link geometry. Otherwise, the geometry is completely different. All (well, most) two-link setups have the same goal: to move the center of rotation to a location that would otherwise be difficult or impossible. BMW i just happen to have an application that moves the center of rotation to the motor spindle, which has obvious benefits in this case.
