BMW 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 heave in your stomach, like watching a list of highlights from the Saw horror movie franchise. If nothing else, the 2021 4 Series might serve as an excellent case study for a new generation of car designers.

Being related to the 3 Series means the redesigned 2021 4 Series gains the same redesign changes of the 2019 3 Series, including more power, a stiffer chassis and new technology features. Even in its base 430i form, it's fun to drive thanks to its responsive four-cylinder engine, tight handling and well-tuned transmission. And that's before you start equipping it with all manner of available performance upgrades.

Overall, we think the 2021 BMW 4 Series is an excellent candidate if you're in the market for a sporty luxury coupe or convertible. Check out the categories of Expert Rating below for our full in-depth evaluation.
