The BMW 4 Series is a 4-door fastback manufactured by the German automaker BMW since 2013. The 4 Series was created when BMW spun off the 3 Series 2-door models into a separate series. BMW unveiled the Concept 4 at the 2019 Frankfurt Auto Show, which was 85 percent representative of the production version, and also form the basis of the all-electric BMW i4. Stylistically, the front is dominated by a large new interpretation of the kidney grille, featuring a more vertical design to distance it from the G20 3 Series.
