BMW Concept 4 is an early look at the next 4-Series

BMW has given us the clearest look yet at its redesigned 4-Series with the Concept 4 unveiled on Tuesday at the Frankfurt International Motor Show.

It’s a bold representation of the upcoming coupe and we’re sure the oversized grille will prove controversial. The vertical design takes inspiration from sporting BMWs of the past like the pre-war 328 and 3.0 CSi of the 1970s.
