More power, sharpened design features, new customisation options and digital innovations: With consistent advancements in the areas related to an exclusive performance experience, BMW M GmbH continues the success story of their bestsellers in the premium midsize segment. The new BMW M4 Coupé and the new BMW M4 Convertible now both highlight even more intensively the motorsport genes of these high-performance models. A 15 kW/20 hp increase in maximum power output for the models BMW M4 Competition Coupé with M xDrive and BMW M4 Competition Convertible with M xDrive, new headlights, laser taillights, M forged light-alloy wheels featuring a new design, steering wheels and interior trims as well as the BMW Operating System 8.5 mark the highlights of further development. Thanks to the current modifications, the high-performance automobiles of the premium midsize segment all have the ideal prerequisites for the continuation of their popularity on international automobile markets, whilst strengthening their leading position within the segment. The USA has become the major sales market for the BMW M4 Coupé, followed by China, Germany and the UK. In the USA, the BMW M4 Convertible accounts by far for the highest sales figures. Moreover, the open-top four-seater enjoys great popularity in Germany and the UK. Both globally and in each of their relevant markets, models of the BMW M4 Series occupy by a clear margin the position as market leaders in each of their respective competitive environments. The straight six-cylinder engine featuring M TwinPower Turbo Technology will in future be available in three performance levels. Still unparalleled in the competitive environment is the combination of the 353 kW/480 hp variant of the power unit with a 6-speed manual transmission in the new BMW M4 Coupé.
The new editions of the BMW M4 Coupé and the BMW M4 Convertible are produced at the BMW Group Dingolfing plant. The worldwide market launch of the new models will begin with the commencement of production in March 2024. Furthermore, the various model variants present themselves as bespoke vehicles, each of them enhancing the extreme sporty driving experience with their very own special facets. For example, a carbon reinforced plastic (CRP) roof is standard on all variants of the BMW M4 Coupé. The BMW M4 Competition Convertible with M xDrive offers a particularly unique opportunity to enjoy M-typical performance along with an extraordinary open-air driving experience. The car’s sophisticated panel bow soft-top roof combines the benefits of a retractable hardtop with the look of a classic fabric roof. The electric drive mechanism allows it to be opened or closed while on the move. Uncompromising dynamics both in everyday driving and on the racetrack are characteristic of BMW M4 Series models, this also being reflected in their design. Powerful proportions and M-specific design features for optimising the cooling air supply and the aerodynamic balance underpin their status as high-performance sports cars. The large, vertical BMW kidney grille sporting M-typical and horizontally arranged double slats, powerfully modelled wheel arches and prominently flared side sills with a contrasting high-gloss black finish as well as attachments for the front and rear aprons provide clear reference to the dynamic potential of both the Coupé and the Convertible.
The straight six-cylinder power units used in the new BMW M4 Coupé and the new BMW M4 Convertible combine the typical high-revving characteristics offered by engines from BMW M GmbH with the current version of M TwinPower Turbo Technology. All variants of the 3-litre engine impress with responsive power delivery and high-torque characteristics up into the highest load ranges. These attributes are responsible for those unmistakable, linear performance characteristics, which have always been the hallmark of BMW M automobiles. M TwinPower Turbo Technology comprises two mono scroll turbochargers, each of them supplying three cylinders with compressed air. Indirect intercooling facilitated by a low-temperature circuit and specific compressors optimise the power output of the charging unit. Moreover, the technology package includes the petrol injection system High Precision Injection operating at a maximum pressure of 350 bar, variable valve control VALVETRONIC and infinitely variable camshaft control Double VANOS. The engine’s design features directly derive from motor racing and include the extremely stiff crankcase, which is manufactured in a sleeveless closed-deck design, the weight-reduced forged crankshaft and the iron coating, which is applied to the cylinder liners in an arc wire spraying process (AWSP). Manufactured in a 3-D printing process, the cylinder head core features an optimised routing of the coolant ducts, something that cannot be realised using conventional metal casting technology. In this way, both weight and temperature management are optimised. Like the cooling system, the oil supply is also aligned to the special demands of racetrack use.
Maximum power output of the straight six-cylinder power unit variant featured in both the new BMW M4 Competition Coupé with M xDrive and the new BMW M4 Competition Convertible with M xDrive has been increased from the previous 375 kW/510 hp to 390 kW/530 hp, this being reached at an engine speed of 6,250 rpm. The further developed engine retrieves maximum torque of 650 Nm within an extended engine speed range of between 2,750 and 5,730 rpm. This results in even more superior and continuous power delivery, thus further enhancing the performance experience above all in highly dynamic driving situations. This exclusive performance specification is realised through a modification of the engine control system, providing further proof of the outstanding potential of the straight six-cylinder engine developed by BMW M GmbH and which serves as the basis for the power plant featured in the BMW M4 GT3 long-distance vehicle.
Like the 8-speed M Steptronic transmission with Drivelogic fitted to all other model variants, the 6-speed manual transmission in the new BMW M4 Coupé is perfectly matched to the performance characteristics of each engine. Shift paddles on the steering wheel for spontaneous manual intervention at each selected driving speed and the Drivelogic button for variable shift characteristics pave the way for a driving experience that is customisable in a variety of ways.High torsional stiffness of the body structure and the suspension connections create the ideal prerequisites for inspiring agility and spontaneous response to steering commands. Model-specific body struts also help the high-performance model provide that BMW M typical combination of dynamic, agile and precise handling. In addition, the most powerful version of the straight six-cylinder engine is combined with intelligent four-wheel drive M xDrive. This gives the new BMW M4 Competition Coupé with M xDrive and the new BMW M4 Competition Convertible with M xDrive outstanding traction, an attribute that is expressed in their impressive acceleration values. Thanks to a rear-wheel biased system and in conjunction with a fully variable Active M differential in the rear wheel transmission, the M xDrive system also enhances that typical M feeling during dynamic cornering. Via the set-up menu the driver is able to select, in addition to the default setting 4WD, the 4WD Sport mode, in which greater percentage of torque is directed to the rear axle. Moreover, when DSC is deactivated, the 2WD mode becomes available for exclusive transmission of power to the rear wheels. M-specific kinematics and elasto-kinematics of the double-joint spring strut front axle and the five-link rear axle guarantee the harmony between extreme driving dynamics and balanced comfort features on all models of the series, both in everyday use and on longer journeys. Three characteristic maps are available via the M Setup menu for individual adjustments of the Adaptive M suspension, which comes as standard. Further components of the suspension technology include M Servotronic steering and the integrated braking system, which is utilised in conjunction both with the standard M compound brakes and the optional M carbon-ceramic brakes.
The integrated application of all drive and suspension systems, which was tested, inter alia, on the northern loop of the Nürburgring, guarantees, also in everyday traffic, highly dynamic and precisely controllable handling. A form of driving pleasure that is unique within the competitive environment is provided by the stability control system DSC (Dynamic Stability Control), which in addition to the M Dynamic Mode comprises ten-stage adjustable wheel slip limitation. By means of the M Traction Control function, optionally available for the BMW M4 Coupé and standard on all Competition models, the driver is able to reduce system interventions in stages in order to cautiously approach the physical limits of driving when the car is used on the racetrack, for instance. The M Lap Timer and the M Drift Analyser provide functions that emphasise the character of these high-performance models as ultimate driving machines for use on closed-off roads.Axle-specificwheel sizes ensure a particularly comprehensive transfer of lateral forces during dynamic cornering. The new BMW M4 Coupé and the new BMW M4 Competition Coupé both come as standard with 18-inch M forged light-alloy wheels at the front and 19″ at the rear. The standard configuration of the BMW M4 Competition Coupé with M xDrive and the BMW M4 Competition Convertible with M xDrive comprises M forged light alloys of the size 19″ at the front and 20″ at the rear. The combination of 19″ and 20″ M light alloys is also optionally available for the new BMW M4 Coupé and the new BMW M4 Competition Coupé. New to the range of special equipment for all model variants are M forged light-alloy wheels in the above sizes featuring a double-spoke design and, for the first time, with a silver finish. Their brightly shining surfaces provide for a sporty, sophisticated and elegant look.
The modern motor racing ambience inside the new versions of the high-performance models has also undergone further development. New steering wheel designs and control elements as well as high-class materials for the instrument panel and interior trims enhance the exclusive ambience inside the M-specific sportscar cockpits. Furthermore, the M-specific cockpit arrangement also includes a control panel on the centre console, on which the shift lever or gear selector switch, the red Start/Stop button, the BMW iDrive Controller, the Setup and M Mode buttons are situated. These can be activated for individual vehicle configuration as well as for the range of functions of cockpit displays and driver assistance systems, which can be adapted to suit the driving situation at hand. The standard M leather steering wheel with multifunction buttons, two M buttons and shift paddles for the Competition models now convey to the driver an even more intensive racetrack feel. The new design comprises a flattened lower section of the steering wheel rim and concisely modified spokes. A red centre marking in the 12 o’clock position underscores the sportive orientation of the steering wheel design. Moreover, for the first time, an M Alcantara steering wheel is available with the same design and range of functions. In addition, a heating function is optionally available for both steering wheel variants. Characteristic of M is also the combination of sporty flair and premium ambience inside the vehicle. This is, amongst other things, the result of high-quality design and finishing of the materials used for the interior. The interior trims in the area of the dashboard, the control panel and the cupholder cover now come as standard in the version Dark Graphite matt. Interior trim strips in Aluminium Rhombicle Anthracite as well as in the new variant Finely Polished Aluminium can now be ordered as options for the new BMW M4 Coupé and the new BMW M4 Convertible. The optional instrument panel in the version Sensatec boasts a further refined surface structure.
The M sports seats come as standard and offer manifold electrically operated adjustment options, integrated headrests and illuminated model logos. The ideal position behind the wheel can be stored using the memory function. Heated seats for both driver and front passenger are also standard, with seat ventilation as an option. The standard leather trim Merino, the all-leather trim Merino, the extended BMW Individual leather trim Merino and the BMW Individual all-leather trim Merino are all available in four different colours. The optional and also fully electrically adjustable and heated M Carbon bucket seats provide for an optimised connection between driver and vehicle. They combine motor racing functionality with lightweight design, cutting-edge workmanship and a high level of long-distance comfort. The use of CRP for the structural elements of the seat and backrest, as well as cut-outs within the area of the side bolsters and beneath the headrests result in a weight reduction of 9.6 kilos compared with the standard sports seats. In addition, an Air Collar system can be ordered as an exclusive option for the BMW M4 Competition Convertible with M xDrive. It generates a three-stage adjustable airflow, providing pleasant warmth from behind to both driver and front passenger, also during open-top driving and regardless of the outside temperature.
A model-specific M Carbon exterior package is available for precise customisation of these high-performance automobiles, bringing to the fore the racing character of both models even more intensively. The M Carbon exterior package includes inserts for the wide-open front air intakes and a rear diffuser, each featuring its own geometry, exterior mirror caps and – exclusively for the BMW M4 Coupé – a CFP rear spoiler. Vehicle weight has been reduced by up to 25 kilos thanks to the likewise optionally available M Race Track package, which also includes, in addition to M Carbon ceramic brakes, M Carbon bucket seats for both driver and front passenger as well as interior trim strips in High Gloss Carbon Fibre. BMW Performance Parts provide additional options for adapting the intensive driving experience and the dynamic aura of the new high-performance sportscars to suit the driver’s very own preferences. The spectrum of model-specific retrofit options encompasses exterior CFP components, M Performance forged wheels with centre lock, M Performance floor mats and M Performance steering wheel trims for individualisation of the interior. The power plant in the new BMW M4 Competition Coupé delivers a maximum power output of 375 kW/510 hp, transferring power to the road via an 8-speed M Steptronic transmission with Drivelogic. In combination with M xDrive featured in the four-wheel drive variants of both the Coupé and Convertible, this transmission guarantees extremely superior transformation of power output – now increased to 390 kW/530 hp – into exhilarating driving dynamics.
