2020 BMW 3 Series vs. 4 Series: Design & Style

The BMW 3 Series was an all-new design for the 2019 model year, featuring the latest in BMW engineering, technology and design. Its LED headlights and chrome line exterior trim lend it a premium look. Much like its lauded predecessors, the 2020 BMW 3 Series sedan combines an engaging driving experience with a classy, refined presentation. It's available only as a sedan.

For its part, the 2020 BMW 4 Series is ever-so-slightly smaller overall than the 3 Series.

It also comes with LED fog lights as standard, a feature that isn't standard on the 2020 BMW 3 Series. Coupe and Convertible models come with four seats and two doors while the Gran Coupe gets four doors and a more traditional rear bench seat with room for a total of five occupants.
