The boost stays finely adjustable even in the highest rev ranges. And thanks to numerous motor sport technologies such as the Active M Differential or M Servotronic, the BMW M4 Convertible reacts in every situation exactly as you expect of a top-class athlete: with high precision and absolute technical perfection.

COMPETITION PACKAGE.

Pure motorsport sensation: With the Competition package, you transfer even more dynamics and agility to the street – thanks to enhanced engine output, specially attuned Adaptive M suspension, newly adapted Dynamic Stability Control (DSC), the Active M Differential and 20'' M light alloy wheels with mixed tyres. The modifications to the suspension include new springs, dampers and stabilisers as well as adapted Comfort, Sport and Sport+ driving modes.

The power of the M TwinPower Turbo 6-cylinder petrol engine is boosted to 331 kW/450 hp. The M sports exhaust generates an extremely powerful and distinctive engine sound - with goosebumps guaranteed. For the exterior, just one of the many impressive features are the exclusive forged and gloss-lathed 20'' M light alloy wheels Star-spoke 666 M with mixed tyres. These wheels have also been optimised with regard to rigidity. The sporty character is further emphasised by the BMW Individual high-gloss Shadow Line with extended contents, which extends from the front ornamental grille across the gill elements to the model designation in high-gloss Black, culminating powerfully in the Black Chrome tailpipes.    

 

ACTIVE M DIFFERENTIAL.

The Active M Differential variably distributes the drive torque between the two rear wheels to optimise traction and driving stability during dynamic lane changing or accelerating out of curves, when making curves at high speeds or on roads with uneven surfaces, including on snow, gravel and ice. It even provides precise handling during extreme lateral acceleration. The constant, smooth adjustment of the differential lock harmonises the vehicle's driving performance, improving control in extreme driving situations.
Traction is optimised with the help of an electronically operated device that reduces the difference in revolution speed between the rear wheels. The system, which was developed for motor sports, is connected to the Dynamic Stability Control (DSC) via an electronic control unit. It proactively provides the perfect use of locking action between 0 and 100 percent, neutralising even the finest differences in torque between the rear wheels – without the tendency to understeer. The Active M Differential provides optimal grip as well as great directional stability and perfect handling, and it converts virtually all of the engine's drive power into acceleration.

LAUNCH CONTROL.

The M dual-clutch transmission with Drivelogic is an innovative 7-speed dual-clutch transmission specially designed for the BMW M high-rev engine. The system boasts a traction-optimised automatic gear selection, Launch Control, Low Speed Assistance, as well as the Automatic Start/Stop function. It makes it possible to change gears extremely quickly without any loss in power. Two sub-transmissions, each with its own clutch, continuously relay the power of the engine to the rear wheels.
The system can be controlled automatically, or manually using the gearshift paddles on the steering wheel or gear lever. Just as with Launch Control, which allows maximum acceleration from a standing start, an extremely dynamic driving experience is the result: Shifting gears at high speed is possible without using the clutch, and without any interruption in the power delivery. Drivelogic can be automatically (D mode) or manually (S mode) controlled, and in each mode three shifting options are available: extremely sporty, comfortable or efficient.

BMW EFFICIENT LIGHTWEIGHT.

BMW EfficientLightweight has the highest priority with M vehicles. That is because low weight is the basis for outstanding driving dynamics and exemplary efficiency. BMW M has consistently applied this insight to vehicle construction – and has been continually refining it. Our engineers constantly ask themselves: Where does it make sense to reduce weight and where does it not? The result: BMW EfficientLightweight.

This involves the use of ultra lightweight materials such as CFRP (carbon fibre reinforced plastic), magnesium or aluminium in targeted areas of the car. For example, the single-piece CFRP drive shaft minimises rotating mass and a CFRP precision strut brace provides significantly higher rigidity than aluminium but with a lower weight. In the front bonnet, light materials in the front side walls, crossmembers and steering wheel frame also reduce weight.

All of this reduces vehicle mass and lowers the car's centre of gravity while maintaining the highest safety standards, achieving greater agility and dynamics in curves and improving acceleration and braking.

ADAPTIVE M SUSPENSION.

The Adaptive M suspension's electronically controlled shock absorbers constantly adjust to road conditions as well as driving style within milliseconds, guaranteeing optimal road contact in every situation, the best possible traction and even more agile handling. The suspension settings can be adjusted from comfortable to sporty-dynamic via the Comfort, Sport and Sport+ modes.
Comfort mode ensures comfortable handling during everyday driving, and also increases safety in case sudden swerving is necessary. In Sport mode, ample comfort is maintained, but dampening is reduced and contact with the road is more direct – ideal for country roads and uneven racecourses. Sport+ mode offers minimal dampening and maximum driving dynamics on level roads and racetracks.

BRAKES.

One decisive factor for a highly dynamic driving experience in the BMW M4 Convertible are the brake systems.With their unbeatable precision, the M Carbon Ceramic Brake System and the M compound brakes ensure unrivalled dynamics and performance.

  • M Carbon Ceramic Brake System.

    The M Carbon Ceramic Brake System stands for consistent technology transfer from the area of motor sports. The application of an innovative carbon-fibre compound ceramic makes the braking power even more direct and improves brake-fade stabilisation. It also doesn't corrode, tolerates more heat, features strongly reduced abrasion and contributes to lower vehicle weight. Systematic implementation of lightweight construction reduces rotating and unsprung mass, improving acceleration, responsiveness and overall handling, but also increasing the driving dynamics, traction and suspension comfort, and reducing fuel consumption.
    With its enlarged brake dimensions (400 mm front, 380 mm rear) and increased number of pistons, the M Carbon Ceramic Brake System's heat resistance in continuous operation makes it fit for the racecourse. The perforated, ventilated brake disc rings guarantee optimal responsiveness in wet conditions, as well as ideal heat dissipation. The 6-piston fixed-calliper brakes in front and the 4-piston fixed-calliper brakes in the rear are recognisable because of their brake callipers in Gold Metallic, as well as the characteristic M logo.

    Dependent on conditions and usage, features specific to the materials used can lead to operational noises particularly in wet conditions just before the vehicle comes to a stop. The impact of moisture and road salt can cause the braking action to be equivalent to a conventional brake system. This can for a short time be experienced as a reduction in braking action and can be
    balanced out by greater pressure on the pedal where necessary.
     

  • M compound brakes

    M compound brakes have benefited from technology-transfer from motor sports, allowing them to maintain constant effectiveness and brake-fade stabilisation, even under demanding usage. The use of various highly resilient materials results in excellent thermal stability, a long lifespan and precise control. It also reduces the brakes' weight, which has a positive impact on agility, dynamics and acceleration.
    The perforated, ventilated brake disc rings (380 mm front, 370 mm rear), and the brake callipers with four pistons in front and two in the rear guarantee optimal responsiveness in wet conditions, as well as improved heat dissipation. The brake callipers in blue metallic with the characteristic M logo strongly emphasise the brake discs' sporty appearance and distinct, authentic M design.

M SERVOTRONIC.

M Servotronic adjusts the power steering to suit the current speed and ensures a direct and precise steering response even at high speeds. It also ensures supreme comfort by minimizing the physical effort required for steering, as well as maximizing agility when parking, manoeuvring or navigating narrow or twisting roads.

7-SPEED M DUAL-CLUTCH TRANSMISSION WITH DRIVELOGIC.
