BMW have expanded the new M4 line up with the addition of a convertible model.

Signature M design features combine with a new panel bow soft-top roof to offer the combination of a high-performance sports car that offers the unique allure of driving with the roof open.


The roof combines the practical benefits of a retractable hard roof with an aesthetically elegant fabric hood. The soft tops electric drive mechanism can be opened or closed at the touch of the button, even while on the move. The boot capacity of 300 litres increases to 385 litres when the roof is closed.


Dynamic design lines set a tone of sporty elegance despite the position of the roof. M design features throughout are just as much functional as they are decorative. All lines converge on the vertical kidney grille, which together with large apertures on either side channel sufficient air towards the braking system and powertrain at all times.


The flared wheel arches, M side gills and extended side sills form a black band around the entire car. A familiar M touch is the black diffuser that frames the exhaust system’s two pairs of twin tailpipes.


Under the bonnet

Providing the power to back up the aggressive, sporty styling is the same 3.0-litre six-cylinder in-line engine found in the current M4 models. This technological advanced power plant provides high-revving performance to the tune of 373kW and 650Nm, the latter from as low as 2 750rpm.


Power is transferred to the road via an eight-speed M Steptronic transmission complete with Drivelogic. The transmission is paired to a M xDrive drivetrain, ensuring optimum traction, which allows the M4 Competition Convertible to reach 100km/h from standstill in just 3.7 seconds and 200km/h in 13.1 seconds.


The rear wheel bias of the M xDrive system ensures the signature M feeling and this can be altered even further as per the driver’s preference via 4WD Sport mode, which directs a greater proportion of engine power to the rear wheels. Drivers can also turn off the traction control system completely or engage two-wheel drive mode, which allows skilful drivers to enjoy a pure driving experience.


To ensure that the chassis remains as stiff as necessary despite the convertible design bracing elements focussed on enhanced dynamics include an aluminium shear panel in the front-end structure, underfloor bracing elements and a rear axle with a rigid connection to the body.


Sporty interior

The interior blends premium materials with motorsport inspired touches. Electrically adjustable and heated M Sport seats as well as extended Merino leather are fitted as standard, while neck warmers and seat ventilation are available as options as are heated M Carbon bucket seats.


A setup button on the centre console enables direct access to a myriad of engine, chassis, steering, braking system and M xDrive settings. To pre-configured profiles can be stored and activated by the M buttons on the steering wheel.


Standard equipment includes three-zone automatic climate control, LED interior lighting, a hi-fi speaker system and BMW Live Cockpit Professional that features navigation and BMW Intelligent Personal Assistant.

A long list of driving assistance systems includes steering and lane control assistant with active navigation system and emergency lane assistant.



Production of the new BMW M4 Competition Convertible will begin in July 2021 at the BMW plant Dingolfing.
