Found this in the BMW technical information system which seems to indicate there will be an xDrive version of the G87. It shares the same service information as the M4c w/xDrive.
* I would caution anyone from thinking this is a sure thing, but it is rather interesting.
Looking forward to the "
I will only get the M2 if it comes with xDrive" and "
I will never buy an M2 with xDrive" discussion.
