When it comes to the premium segment of the midsize class, the number 4 stands for the perfect combination of driving pleasure and elegantly sporty design. These have been hallmark brand values of BMW since its earliest days, and the new BMW 4-Series Coupé and new BMW 4-Series Convertible embody them even more intently than ever. The precisely modified exterior design of the two models underscores their dynamic character and exclusive style. Modern touches and new equipment features bring a premium ambience of renewed sophistication to the interior. Here, the cutting-edge cockpit design, including the BMW Curved Display, provides the ideal stage for the latest evolution of BMW iDrive with QuickSelect, which is based on the new BMW Operating System 8.5. Production of the new BMW 4-Series Coupé and new BMW 4-Series Convertible will remain at BMW Group Plant Dingolfing, which is also the birthplace of many other executive class and luxury segment cars from the brand, as well as the BMW 8-Series sports car and the high-performance BMW M4 models. Its worldwide market launch will get underway in March 2024. New exterior paint finishes and light-alloy wheels, headlights with an extremely striking design for the light sources and the now optionally available Laserlight rear lights mark out the latest advances in the exterior of the two models. Step inside the sporting two-door models and the key new features of the cabin are immediately apparent: the revised design of the steering wheels and instrument panel, the seat coverings, the interior trim elements and the now optionally available CraftedClarity glass applications for selected controls. Alongside the introduction of the new BMW iDrive with QuickSelect as standard, customers can now also choose to add an Augmented View display for the BMW Maps navigation system as an option on their new BMW 4-Series.
For the past two model generations, BMW has grouped its premium midsize coupés and convertibles into their own model range. This has highlighted their particularly intense focus on delivering the driving pleasure for which the brand is renowned. The differentiation between the new BMW 4-Series models and the BMW 3-Series in terms of design can be found not only in their proportions and lines, but also their distinctive front-end visuals. Wider tracks and specific tuning for their chassis technology lay the groundwork for superlative dynamic prowess. Within the BMW 4-Series range, the coupé and convertible models represent distinct characters whose individual vehicle concepts target different priorities. The BMW 4-Series Coupé combines its dynamically flowing lines and elegantly stretched proportions with a body optimised for extra handling agility and boasting exceptional torsional rigidity, plus a chassis tuned squarely for dynamic excellence. The individual-seat character of the two rear seats helps to ensure that the passengers in the second row also enjoy an intense driving experience. Meanwhile, passengers in the BMW 4-Series Convertible’s four seats can sample the sporty driving experience characteristic of the 4-Series together with the joy of open-top motoring. A particularly stylish sense of elegance, for which the car’s low-slung silhouette is principally responsible, also comes as standard. A highlight feature specific to the BMW 4-Series Convertible is its panel bow soft-top roof, which combines the solidity of a retractable hardtop with the classical aesthetic of a fabric hood. The roof’s electric drive mechanism can be activated while travelling at up to 50 km/h (31 mph); the opening/closing process takes 18 seconds.
The evolution of the BMW 4-Series range is anchored in the product substance that has helped it achieve such outstanding popularity across all the major car markets. In a market dominated by German premium carmakers, the coupé and convertible enjoy clear leads in their respective segments both globally and in their key individual markets. This sales success has been accompanied by an extraordinarily high level of customer satisfaction. In customer surveys, both the BMW 4-Series Coupé and BMW 4-Series Convertible achieve excellent approval ratings. Customers placed particular emphasis on the dynamic driving characteristics and emotionally rich design of both models, as well as a premium feel characterised by high material and build quality. By attracting such positive responses from customers, the BMW 4-Series models have made a significant contribution to further enhancing the brand’s profile as a maker of dynamically exceptional and elegantly sporty premium cars. The most important sales markets for the new BMW 4-Series Coupé and new BMW 4-Series Convertible are the USA, Germany and China. Since the market launch of the current model generation of the BMW 4-Series Coupé, the US market has recorded the strongest demand. The BMW 4-Series Convertible has also been most popular in the USA to date.
The introduction of the upgraded BMW iDrive with QuickSelect also brings improved operation of the ventilation and climate control functions in the new BMW 4-Series Coupé and in the new BMW 4-Series Convertible. This is a prime example of advanced digitalisation at work and enables a further reduction in the number of physical buttons and controls in the cockpit. Temperature selection, intensity of ventilation and – if the relevant features are specified – seat and steering wheel heating can now be adjusted by touch via the BMW Curved Display or by voice command with the help of the BMW Intelligent Personal Assistant. New adjustment controls for the air vent grilles in the centre of the instrument panel and on the driver’s and front passenger side of the cockpit allow the direction of airflow to be adjusted using rotating and tilting movements. Specifying optional Sensatec trim for the instrument panel means customers will now find a further refined surface structure which further highlights the interior’s modern premium ambience. The standard ambient lighting in the new BMW 4-Series Coupé and new BMW 4-Series Convertible now also includes contour lighting integrated into the trim around the central seam vents. Like the lighting for the footwells, the storage compartment in the front section of the centre console and the door openers, this can be adjusted for colour and brightness according to personal preference. Users can choose from nine colours. The functionality of the interior lighting also includes an atmospheric Welcome and Goodbye Animation and light signals indicating an open door or incoming phone call.
High-quality, meticulously crafted materials and a new operating concept for ventilation and climate control systems add to the cockpit’s premium allure. The modifications carried out to the interior of the new BMW 4-Series Coupé and new BMW 4-Series Convertible ensure those on board can enjoy driving pleasure with progressive style and long-distance comfort in an ambience of carefully honed refinement. Among the cutting-edge new features is a version of the optionally available seat surfaces that is making its debut in the new BMW 4-Series Coupé and is produced using more sustainable methods. Added to which, new interior trim strips are available for both the coupé and convertible. And standard specification now also includes ambient lighting and electrically folding exterior mirrors. The range of optional equipment has been restructured to enable particularly targeted individualisation. The latest-generation steering wheels available for the new BMW 4-Series Coupé and new BMW 4-Series Convertible stand out with their modern and sporty design. As standard, the driver will find in front of them a newly designed sports leather steering wheel with a polygonal rim and two spokes. The M Sport package now brings an M leather steering wheel in three-spoke design with a flat-bottomed rim and a discreet centre marking. Both versions of the newly designed steering wheels have illuminated multifunction buttons and gearshift paddles. Now fitted as standard, the paddles enable particularly swift manual interventions in the gear selection process and underscore the sharper sporting profile of the new BMW 4-Series models.
All the six-cylinder in-line engines available for the new BMW 4-Series Coupé and new BMW 4-Series Convertible, as well as the four-cylinder diesel unit, come with 48V mild hybrid technology for sharper power delivery and greater efficiency. The auxiliary electric drive takes the form of a 48V starter generator and makes output of 8 kW/11 hp instantly available in response to the slightest movement of the accelerator. This electric boost enhances the drive system’s dynamic response when accelerating off the line and putting in mid-range bursts of speed. The electric drive unit also assists the engine when travelling at a constant speed, allowing it to operate within an efficiency-optimised load range as often as possible. The mild hybrid system additionally allows the use of electric power recuperated via Brake Energy Regeneration and stored in a 48V battery. The energy harvested efficiently in this way is not only used for the auxiliary electric drive, but also fed to the 12V electrical system with the help of a voltage transformer. This allows the vehicle’s electrical consumers to be operated even more efficiently.
The line-up of powertrains for the new BMW 4-Series range comprises powerful and highly efficient petrol and diesel engines featuring BMW TwinPower Turbo technology and electrification in the form of 48V mild hybrid technology. All the drive units deliver an exceptional blend of sporting driving pleasure and fuel economy, all are part of the current modular generation of Efficient Dynamics engines and all are mated to an eight-speed Steptronic Sport transmission as standard. The shift paddles on the steering wheel, which also come as standard in the new BMW 4-Series Coupé and new BMW 4-Series Convertible, allow quick manual interventions in the gear selection process, adding to the dynamic driving experience. Straight-six engines can be found under the bonnet of the M Performance versions in both model series, as well as in the new BMW 430d xDrive Coupé and BMW 430d Convertible, whose diesel unit has an output of 210 kW/286 hp. The line-up also includes two four-cylinder petrol engines developing 135 kW/184 hp and 180 kW/245 hp respectively and a 140 kW/190 hp four-cylinder diesel. The engine’s power is fed to the road via either classical rear-wheel drive or the BMW xDrive intelligent all-wheel-drive system, depending on the model variant.
The new BMW 4-Series Coupé and new BMW 4-Series Convertible range is spearheaded by elite sporting models cast in the familiar M mould. The performance cars from BMW M GmbH showcase the dynamic potential woven into the vehicle concepts of the BMW 4-Series range to highly impressive effect. Extremely powerful six-cylinder in-line engines, a bespoke chassis set-up and signature M design cues both inside and out mark them out as a proposition apart. The M Performance models in the BMW 4-Series are available with both petrol and diesel engines, each with a displacement of 3.0 litres. The M-typical performance attributes of these straight-six units are underpinned by, among other things, the latest M TwinPower Turbo technology – which is tailored individually to the engine at hand. Another shared feature is the 48V mild hybrid technology, whose output of 8 kW/11 hp produces an electric boost effect that gives the engines even sharper response. The six-cylinder in-line petrol engine in the BMW M440i xDrive Coupé and BMW M440i xDrive Convertible generates maximum output of 275 kW/374 hp and peak torque of 500 Nm (369 lb-ft). The BMW M440d xDrive Coupé and BMW M440d xDrive Convertible, meanwhile, are powered by a straight-six diesel unit that produces maximum output of 250 kW/340 hp and peak torque of 700 Nm (516 lb-ft). M Sport suspension with variable sport steering can be found on the standard equipment list for the range-topping models, along with an eight-speed Steptronic Sport transmission with an ultra-sharp shift action, M Sport brakes and the M Sport differential.
