　　Cameron Rogers has worked in the automotive industry since 2013. He has tested and reviewed hundreds of vehicles over the course of his career. Today, he leads the news team in developing cutting-edge news articles, opinion pieces and sneak peeks at upcoming vehicles. Favorite cars that he's driven during his tenure at zzdcar include the 991-era Porsche 911 Turbo S, Rolls-Royce Ghost and several generations of Honda Odyssey (really).

　　The 4 Series is made for those who prefer a sporty two-door coupe or the drop-top experience of a convertible over a traditional sedan. It's based on the 3 Series but has a higher starting price. The separately reviewed Gran Coupe model has four doors like the 3 Series and is about the same size but differentiates itself with a different front end and a sportier design. For 2024, BMW updated the 4 Series' interior with a 12.3-inch digital instrument cluster and a larger 14.9-inch center touchscreen housed behind a single curved display. The high-performance M4 is reviewed separately.

zzdcar spotlight: M440i's power and efficiency

Under the hood of the M440i is a potent turbocharged 3.0-liter inline-six engine that produces 382 horsepower and 369 lb-ft of torque. That's more than enough power when puttering around town and plenty of grunt for the open road. The M440i convertible blasted from 0 to 60 mph in just 4.6 seconds when we tested it. But its mild hybrid engine is also efficient. The rear-drive coupe model gets an impressive 27 mpg in combined city/highway driving, and the heavier convertible is rated at 26 mpg. For comparison, the significantly less powerful 255-hp 430i gets 28 mpg combined.

　　

Competitors to consider

The 4 Series has few rivals because there aren't many luxury automakers that offer three body styles under one nameplate. The Audi A5 is a direct rival that does and the upcoming Mercedes-Benz CLE will offer a coupe and convertible. If you don't mind going the non-luxury route, the V8-powered Ford Mustang GT is another alternative that's available as a coupe and convertible.

Performance

8.0/10

　　How does the 4 Series drive? We tested a rear-wheel-drive M440i convertible. It packs a lot of punch, and in our testing it ripped from 0 to 60 mph in 4.6 seconds — a full second quicker than a similarly equipped 430i coupe we also tested. Acceleration is punchy at highway speeds, too. It stopped from 60 mph in 109 feet, which is a few feet longer than that 430i, though the coupe weighed roughly 500 pounds less.

　　Unfortunately, the brakes are grabby at low speeds and require a delicate foot to slow smoothly. The automatic engine stop-start system is also clunkier in the M440i than in the 430i, and it doesn't have a dedicated disable button.

　　The steering is a little vague during truly spirited driving. It's a mild disappointment in a BMW, though the reality is that rivals aren't appreciably better in this regard. Handling is a 4 Series strength, with stable composure around tight bends and a seemingly high limit for traction control intervention. The eight-speed automatic shifts smoothly and always seems to be in the right gear, making this an easy car to live with.

　　

Comfort

8.5/10

　　How comfortable is the 4 Series? BMW makes some of the best front seats in the business. They are comfortable and feature multiple adjustments — including side bolster angle and thigh extension — that allow you to find an ideal sitting position.

　　The M440i's standard adaptive suspension provides a surprisingly supple ride. Wind and tire noise is kept to a minimum too. The only real misstep is the climate system. We appreciate a tri-zone system in such a small convertible, but the automatic function bizarrely does not adjust fan speed. The sync function is also buried in a touchscreen menu.
