The second-generation BMW M4 Convertible (G83), introduced in May 2021, brings all-wheel drive and a 510-horsepower engine to the brand's high-performance drop-top lineup. It transitions back to a lighter soft top while sharing its aggressive styling and advanced drivetrains with the M4 Coupe.
BMW M4 Convertible (G83) at a glance
Quick model context before comparing photos and trim-level specifications.
Entering its second generation under the G83 designation, the BMW M4 Convertible takes a significant step forward in performance by adopting the xDrive all-wheel-drive system as standard. Available exclusively in the high-output Competition trim, this convertible is designed for drivers who want the intense dynamics of an M car combined with an open-air experience. A major shift for this generation is the abandonment of the folding metal roof in favor of a traditional fabric soft top, which reduces weight and lowers the vehicle's center of gravity. Despite carrying an additional 145 kilograms of structural bracing compared to the coupe, the convertible maintains rapid acceleration and sharp handling thanks to adaptive suspension and a reinforced chassis.

BMW M4 Convertible (G83) overview
Editorial context for design, cabin, performance, practicality, and buyer notes.
Design
The exterior styling directly mirrors the bold aesthetic of the M4 Coupe, highlighted by a large vertical kidney grille, narrow headlight clusters, and a heavily sculpted front bumper designed for optimal airflow. The rear features a prominent diffuser housing four 100-millimeter exhaust pipes with active valving. Replacing the previous generation's hardtop, the new fabric roof is 40 percent lighter and can be operated at speeds up to 50 km/h, taking just 18 seconds to open or close. Buyers can specify the soft top in standard black or an optional Anthracite Silver Effect.
Interior
Inside, the cabin layout is shared with the standard 4 Series but upgraded with M-specific components. The driver interacts with a thick-rimmed sport steering wheel featuring customizable M1 and M2 red shortcut buttons. Standard sport seats provide aggressive bolstering, while optional carbon-fiber bucket seats offer an even more track-focused setup. To enhance comfort when driving with the roof down, the front seats can be equipped with an integrated neck warmer system, and a rear wind deflector is available to reduce cabin turbulence. A 408-watt Harman Kardon audio system provides high-quality sound.
Performance
Powering the M4 Convertible is a 3.0-liter twin-turbocharged inline-six engine producing 510 horsepower and 650 Nm of torque. This output is sent through an eight-speed ZF M Steptronic automatic transmission to an active M xDrive all-wheel-drive system. The setup propels the 1,920-kilogram convertible from 0 to 100 km/h in 3.7 seconds. The xDrive system includes a standard 4WD mode, a rear-biased 4WD Sport mode, and a 2WD mode that disconnects the front axle entirely for traditional rear-wheel-drive dynamics. An active rear differential and adaptive dampers come standard.
Practicality
As a four-seat convertible, the M4 G83 requires some packaging compromises compared to the coupe, primarily regarding cargo space. The trunk offers 385 liters of volume, though utilizing the folding roof mechanism impacts usable storage limits. The shift to a soft top slightly improves packaging over the older hardtop design. Measuring 4,794 mm in length with a 2,857 mm wheelbase, it provides reasonable cabin space for a two-door sports car, though rear seating remains well suited for shorter trips or smaller passengers.
Safety and tech
The M4 Convertible includes modern driving assistance technologies offering Level 2 autonomy. Visibility is aided by optional laser-phosphor headlights, while a head-up display keeps essential data in the driver's line of sight. For track enthusiasts, the optional M Drive Professional package adds a 10-stage traction control system, an M Laptimer, and an M Drift Analyser. The available M Race Track package upgrades the hardware with carbon-ceramic brakes, lighter wheels, and track-ready semi-slick tires.
Buyer notes
Because the G83 generation is offered strictly in Competition specification with all-wheel drive, buyers do not have to deliberate over engine outputs or drivetrain layouts. The primary choices revolve around track-focused hardware versus grand touring comfort. Consider the M Race Track package if you plan on closed-course driving, but be aware that the carbon bucket seats sacrifice some daily comfort. For those who frequently drive with the top down in cooler weather, the neck warmer option is highly recommended.
