NEW BMW 4 SERIES 2021

BMW's two-door 4-series differentiates itself from the 3-series sedan with a controversial new design and a more elegant roofline. Mechanically, the two cars are almost identical. They are powered by the same two powertrains: either a 255-hp turbocharged four-cylinder or a 382-hp turbocharged inline-six. While passenger space is obviously arranged differently inside the two-door 4-series, occupants are treated to the same basic interior design, layout, and features as in the four-door—and as fans of BMW's latest interior arrangement we're okay with that. BMW says the new 4-series will start rolling out this fall, when it will take on other premium two-door models such as the Audi A5, the Lexus RC, and the Mercedes-Benz C-class. Fans of the fastback 4-series Gran Coupe sedan or the high-performance M4 (both reviewed separately) will be happy to know that those models will continue to be offered.
