What is the 4 Series?
Beauty is in the eye of the beholder, and no car embodies that spirit more than the redesigned 2021 BMW 4 Series. Essentially a two-door version of the BMW 3 Series sedan, the 4 Series coupe and convertible look sleek and sophisticated from the side and predictably sporty from the rear. Glance at the 4 Series head-on, though, and the sight of the bucktoothed grille might elicit a shriek of terror. If nothing else, the 2021 4 Series might serve as an excellent case study for a new generation of car designers.
