Overview
From the driver’s seat, there’s little that differentiates the 2023 BMW 4-series from the 3-series sedan on which it’s based, and that’s a good thing. But on the outside, the two-door body style and oversize twin-kidney grille give the 4-series a look entirely different from its four-door, 3-series counterpart. Practicality takes a back seat here, literally, as the 4-series’ rear seat is snug; nor is its trunk as spacious as the 3-series’ cargo hold. But if anyone cares, they can opt for the 3-series sedan. The 4-series duo is stylish, quick, and refined as you’d expect BMWs to be. What’s missing, however, is the brand’s traditionally sharp handling, especially if you go with the entry-level 430i model, which comes with a turbocharged four-cylinder engine. Opt for the more powerful M440i, which sports a rambunctious turbocharged inline-six, and things get a lot more interesting—but even its backroad moves aren’t as special as we would hope. The 4-series Gran Coupe exists for buyers who want both swoopy styling and four doors, but we review that model separately.
What's New for 2023?
BMW’s entry-luxury coupe and convertible are largely unchanged for 2023, but M Sport brakes with red or blue calipers are now a part of the optional Shadowline appearance package. The Premium package no longer includes BMW’s gimmicky gesture controls for the infotainment system, and the optional head-up display is now only available on top-spec M440i models. A Parking Assistance package has been added to the options sheet, and all models now come with a faux-leather dashboard cover.
We think the turbocharged inline-six in the M440i model is the enthusiast's choice, but the nearly $11,000 price premium may turn off some buyers. That bump in price comes with a load of additional equipment, though, in case you need more reason to justify the cost. The M440i is outfitted with unique M Sport 18-inch wheels with run-flat tires, the M Sport suspension and rear differential, a rear spoiler, a faux-leather wrapped dashboard, and more. A convertible model is also offered but switching to the soft-top body style adds $7500 to the base price.
Engine, Transmission, and Performance
The same two overachieving engines offered in the 3-series are available in the 4-series. Models designated 430i are powered by a 255-hp turbocharged 2.0-liter four-cylinder. The M440i is powered by a silky-smooth turbocharged 3.0-liter inline-six that gains an assist from a 48-volt hybrid system to make 382-hp. The 4-series provides a sporty driving experience, courtesy of a retuned suspension, a more-aggressive steering calibration, a wider rear track, and a lower center of gravity than the 3-series sedan. Still, we tested the M440i coupe and came away less impressed with its driving character than its terrific inline-six. Apart from strong brakes that performed well in our 70-to-zero-mph test (149 feet), the Bimmer's distant steering and compliant ride didn't deliver the same satisfaction we got from the M340i sedan. During our test drive of an all-wheel drive 430i xDrive model, we noted decent power from the turbocharged four-cylinder but noted a similar complaint about the car's too-soft suspension.
