The 4 Series coupe and convertible pack in the style, luxury, and exclusivity. This plush and comfortable line is lower and wider than its 3 Series sedan brethren. They are more of gentlemanly touring cars than a sportsters, yet they're quite capable. Handling is taut, the ride is steady and compliant, and the interior is plush. The rear seat is relatively spacious. The 2.0-liter four-cylinder turbo is sparing with fuel; the 3.0-liter six-cylinder turbo is super smooth with effortless go. For 2020, the 4 Series gets standard forward collision warning, city-speed automatic emergency braking with pedestrian detection, and lane departure warning.
