BMW Concept 4 Gallery

BMW is no stranger to outlandish design, and one of the most frequent motifs of its cars – concept and production – over the past few years has been a growing grille. The dual kidneys that have become icons on the BMW hood keep getting bigger, and the BMW Concept 4 is no different. Unveiled at the Frankfurt Motor Show 2019, it's definitely distinctive.

BMW says it previews the new 4 Series, and so we should probably get used to this fairly extreme style. Look closer at the chromed nostrils and there's plenty of intricate detail to be found, like facet-cut grille bars. The concept car's lights, too, are intriguing, the LED clusters integrated into the bodywork.

How much of that – or the generally less controversial side and rear design of the BMW Concept 4 – makes it to production remains to be seen.
