What are those diagonal bars behind BMW grills? Is a part that other makes have and that's just more hidden on them? Does anyone else notice it pretty much every time they look at the front of a BMW? Thanks.
So, what do they do? Do other cars have them? If not, how do those models get whatever benefit BMW's get from the diagonal bars? If so, how come we never see them in other cars, even in head-on photos with flash?
