BMW 4 series 2021 Review: Interior, Engine, and Full Specs

The BMW 4 Series Coupe and Convertible didn’t make any big changes in 2021, but there are a few small ones worth mentioning. The more powerful M440i Coupé model is now also available with rear-wheel drive and all panels are now equipped with ambient interior lighting as standard.

The optional premium package now includes gesture control for the wooden stand, head display, and vehicle infotainment system. Two new colors are offered – Brooklyn Gray Metallic and Aventurine Red Metallic – while the standard synthetic leather seats are now perforated.

Engine, Transmission, and Power

Two engines of the same power from the 3 series are also available in the 4 series: The model known as the 430i is powered by a 255 hp 2.0-liter four-cylinder with turbocharging. The M440i is powered by a sleek six-cylinder 3.0-liter turbo engine backed by a 48-volt hybrid system to produce 382 horsepower.

The 4 Series offers a sporty driving experience thanks to a retuned chassis, a more aggressive steering set-up, a wider rear track, and a lower center of gravity than the 3 Series sedan. However, we tested the M440i Coupé and were less impressed by its driving character than the excellent in-line six-cylinder.

Aside from heavy brakes, which worked well in 70 to zero mph (149 ft) tests, the Bimmer’s rubber steering and ride fit didn’t deliver the same satisfaction we got from the M340i sedan. During a test drive of our 430i xDrive all-wheel-drive model, we noticed that the turbocharged four-cylinder engine performed well, but we had similar complaints about the car’s suspension being too soft.

Buyers may not notice much of a difference between the Series 4 and Series 3 cabs unless they are in the back seat. The dashboard layout, interior materials, and main controls look identical to the four-door 3 Series, although we’ve noticed that the 4 Series’ lower roofline looks less spacious.

The trunk is less spacious here than in the 3 Series, especially in the convertible; In our tests, we loaded five hand luggage in the trunk of the coupé model, one less than the 3-series sedan.

Infotainment and Connectivity

The BMW 4 Series has the same 8.8-inch and 10.3-inch infotainment screens as the 3 Series Sedan. The latest version of the BMW iDrive 7 infotainment software runs on both screens, combining an intuitive user interface with a click-wheel controller integrated into the console for easy operation while driving.

Those who prefer to interact directly with the screen can do so, as both are touchscreens. Apple CarPlay, Android Auto, and Dashboard are the standard navigator, while the 12.3-inch digital display e onboard WiFi, and a wireless phone charging pad are optional extras.
