2021 BMW M440i xDrive Coupe: Review

What Is It?
The BMW 4 Series traces its lineage directly to the original 3 Series coupe — the 320i that arrived in the U.S. during the late 1970s fueled the popularity of BMW cars on these shores. The 3 Series went on to add convertible, sedan and wagon versions to the lineup on its way to becoming BMW’s best-selling model of all time. For 2014 BMW renamed the 3 Series coupe and convertible as the 4 Series to differentiate the 2-door models, but then added the 4-door 4 Series Gran Coupe the following year to compete against the 3 Series — and cause confusion in the lineup.
