2020 BMW 4 Series Gran Coupe spied

BMW has been snapped testing the 4 Series Gran Coupe on European streets, revealing details about its profile and rear lights... but nothing about its grille. The new prototype follows the Concept 4 revealed in Frankfurt. The concept, which offers "a look ahead to the expressive face of the 4 Series range" according to BMW, was dominated by its gigantic 'kidney' grille.
