The Chicago Auto Show is now open, but for most European automakers, the event they’re preparing for is the next one on the calendar. The Geneva Motor Show is regarded as one of the biggest auto shows of the year. Every automaker worth its salt attends the event. That includes BMW, which is already in line to debut the new X4. Now, whispers abound that another model is coming to the auto show. If these whispers hold true, we could be on the receiving end of seeing a new, 8 Series-based concept from the M Division.
