Do you guys think that the grills will be functional on the production model? They are on the F30 and I can't think of any production BMWs that have "fake" kidney grills. I don't know why it bothers me, but between that and exhaust notes being artificially enhanced in the cabin (i.e. Z4) some of this stuff is starting to feel gimmicky to me. I think there is still something appealing about the idea of form following function, and the thought that the engineers got the final word over marketing and design.
Maybe closing off the kidneys is form following function in this case, but at that point they should just be eliminated. Who knows.
