The Frankfurt Motor Show happened this past week, and among all the new cars that were shown was one we just couldn’t stop staring at. It’s the BMW Concept 4, which is a two-door concept car that foreshadows what the redesigned 4 Series coupe will look like. We weren’t staring at it because it was so good looking, though. We stared because of its grille, which is a comically large version of BMW’s iconic twin kidney grille. This whole giant grille trend has finally jumped the shark, and we’ve got BMW to thank for it.
