Concept and design

The new BMW 4-Series Gran Coupé extends the model range of vehicles available in the premium midsize class. It combines the sleek look of a two-door coupé with the functionality provided by four-doors and expansive spaciousness, including a wide-access luggage compartment. The sporty and premium character of the BMW 4-Series is combined with intelligent functionality and refined elegance in the Gran Coupé. While this model shares the same length, width, wheelbase and track with the extremely dynamic two-door version, the roofline of the BMW 4-Series Gran Coupé is 112 millimeter longer and slopes gently to the rear of the vehicle. What’s more, the silhouette is twelve millimeters higher to offer more headroom and comfort in the rear passenger compartment. This contributes to increased headroom on all seats and the overall feeling of interior spaciousness. At the same time, the short front and rear overhangs, the long wheelbase relative to the vehicle length, and the set-back passenger compartment are typical BMW touches that add to the perfect balance of the body design and the noble appearance of this car, which is derived from the elegant BMW 6-Series Gran Coupé.

Elegant coupé with saloon car and touring qualities

Like the two-door version, the sporty dimensions of this vehicle are a reflection of its bold and dynamic handling characteristics. The stretched roofline, four frameless doors and a wide, electrically operated boot lid offered as standard provide the functionality of a saloon car within the silhouette of a coupé. The volume of the boot is 480 liters, which is the same capacity provided by the BMW 3-Series Saloon. The back of the rear seat can be folded down in the configuration 40:20:40 as desired to increase the load capacity to 1,300 liters. The flat floor and a two-part loading strip made of stainless steel are practical convenience elements that are combined with premium materials. Thus the BMW 4-Series Gran Coupé can easily transport a pram, two golf bags or six crates of bottled water without using the folding function.

In contrast to a two-door coupé, the BMW 4-Series Gran Coupé offers passengers easier access when entering or leaving the vehicle thanks to the four-door configuration. The doors are frameless, having the characteristic design features of BMW midsize coupés. The wide-access boot lid harmonizes perfectly with the overall silhouette. When closed, the precise flow of the lid seams simulates the look of a typical coupé boot. The electric drives that help move the boot lid reflect perfection in detail. They are installed vertically and require very little space. Thus the area of the rear windscreen is much larger and provides a very good view, without limiting the space available.

At first glance, the BMW 4-Series Gran Coupé is an expression of extreme dynamics and refined elegance. With a length of 4,638 millimeters, a width of 1,825 millimeters and a wheelbase of 2,810 millimeters, the four-door variant has the same dimensions as the two-door coupé. The track dimensions of both models – 1,545 millimeters front and 1,594 millimeters rear – are identical and highlight the dynamic potential of the BMW 4-Series Gran Coupé. The silhouette of the four-door model is twelve millimeters higher than the two-door version. The stretched roofline flows gently across both rear doors and blends into the slightly raised and short rear section of the car.

Athletic, elegant and powerful from any perspective

The BMW 4-Series Gran Coupé is instantly recognizable by classic BMW design features such as the iconic kidney grille and dual round headlight clusters. The body contours are executed with precision, with multifaceted surfaces that distinguish the eye-catching look up front. Full LED dual headlights can be ordered as options to bolster the dynamic aura of the vehicle. The three-part, wide air intakes in the front apron emphasize this effect. The extreme left and right apron corners reveal vertical air channels for the so-called Air Curtains. They generate a veil of air around the front wheels thereby enhancing the aerodynamic efficiency of the BMW 4-Series Gran Coupé.

The sides of the vehicle are distinguished by a bold swage line and a subtle light-catching edge that create the impression of forward movement in the design of the BMW 4-Series Gran Coupé. Stretched lines and expressively contoured surfaces generate a dynamic interplay of light and shadows. The extremely gentle slope of the roofline stretches the appearance of the sides even more and visually strengthens the imposing presence of the BMW 4-Series Gran Coupé. The taut and smooth appearance of the side windows, with a B column finished in high-gloss black that is nearly invisible, makes a homogeneous and high-quality impression. The rear third window in the ensemble is a modern interpretation of the Hofmeister kink that is characteristic of BMW vehicles. This extended window surface allows more light into the interior and improves the overall visibility in the rear passenger compartment.

The rear of the car features clear horizontal lines that accentuate its athletic elegance. The taillights are positioned at the outer edges to receive the swage lines, thus serving as transitional design elements that join the body side panels with the rear section of the automobile. At the same time, they highlight the wide track and powerfully flared wheel arches. When viewed from the rear, the roof of the BMW 4-Series Gran Coupé is somewhat wider than that of the two-door version and thus emphasizes the noble road presence of this premium vehicle.

Stylish elegance and sportiness dominate in the interior

The interior of the BMW 4-Series Gran Coupé presents a stylish fusion of sporty allure and exclusivity. An approach known as layering – the intelligent utilization of space through the structuring of lines and surfaces into layers – expresses the hallmark BMW driver orientation without compromising the passenger experience. The stylish and functional elegance of the interior is highlighted by prominent round instruments with a black panel look and the free-standing flat-screen iDrive monitor. The cockpit and rear passenger compartment are visually joined by trim strips originating in the instrument panel and extending along the upper sections of the door panels into the rear, and embellished by dual-color window sills. The B column blends into the side panel design and includes flowing graphic effects across the entire surface. The side supports and slender head restraints in the rear seat are contoured for a modern, seemingly molded one-piece look that adds to the sporty character of the 4+1 seater.

The backrest can be folded in 40:20:40 configurations to create more luggage and stowage space as required – with a flat floor for easy loading and unloading. When the seat is completely folded down, the maximum volume capacity is 1,300 liters. If only the center segment is utilized, four people can ride comfortably while transporting long and bulky items like snowboards, skis, etc. When not folded down, this middle section provides space for two cup holders. An optional feature is the Smart Opener, which automatically opens the boot lid via gesture control – namely a foot movement underneath the rear bumper when arms are full carrying groceries, packages, etc.

Elaborate suspension technology for the highest degree of comfort, typical BMW handling characteristics, steering and driving precision

Rear-wheel drive, steering free from drivetrain influences and well-balanced 50:50 axle load distribution create the ideal preconditions for dynamic performance, excellent directional stability and agile handling characteristics. A low center of gravity, a meticulously tuned suspension setup and an intelligent lightweight construction concept result in a first-class overall package that combines seemingly contradictory qualities such as maximum dynamics and outstanding riding comfort in a unique way.

The BMW 4-Series Coupé provides the basis for sporting performance

The suspension of the new BMW 4-Series Gran Coupé is modeled on that of the two-door model variant and has the corresponding dimensions. The wheelbase measures 2,810 millimeters, the track width 1,545 millimeters at the front and 1,594 millimeters at the rear (418d: 1,557/1,605 millimeters front/rear; xDrive variants 1,544/1,590 millimeters front/rear). Whilst the axle and elasto kinematics correspond to that of the BMW 4-Series Coupé, suspension and damping were aligned exclusively to the four-door version.

Lastly, specific car body reinforcement measures and an innovative strut concept within the front and rear sections of the vehicle help to enhance steering precision and response. Nevertheless, the four-door coupé is only marginally heavier than the two-door variant and even lighter than its competitors. Consequently, the new BMW 4-Series Gran Coupé is characterized by supreme driving dynamics, agile handling characteristics and a high level of precision. Notwithstanding this, riding comfort does not suffer in any way, so the dynamic four-door car presents itself as a vehicle that is completely suitable for everyday use.

Aluminum double-joint spring-strut axle at the front

The front axle of the new BMW 4-Series Gran Coupé is based on the tried and tested double-joint spring-strut aluminum construction, which combines maximum stiffness with minimum weight and significantly reduces unsprung masses. Furthermore, a torsion bar located between the front axle support and the sill creates an overall stiffer connection between the front wheels and the vehicle. Models with BMW xDrive all-wheel drive technology feature a special combination comprising a load-bearing strut and transverse brace. Moreover, a further strut connecting the suspension domes and the bulkhead significantly enhances the stiffness of the front end. Therefore, the new BMW 4-Series Gran Coupé responds very directly to the driver’s steering inputs, resulting in sporty and agile handling and allowing the car to corner effortlessly and with the highest degree of precision.

All-rounder: five-arm rear axle for comfort and active driving

The rear axle of the new BMW 4-Series Gran Coupé plays a critical role in boosting the car’s dynamic ability and motoring comfort. The proven five-arm concept, extra-wide mounts and supports on the wheel carriers for track and camber, slightly repositioned pivot points, ultra-stiff control arms and axle subframes, and the use of thrust arms to connect the suspension with the body all provide an excellent basis for an extremely sporty overall set-up combined with excellent comfort characteristics. On models with a sunroof, additional torsion bars ensure increased body stiffness at the rear. As a result, the rear axle guarantees precise wheel guidance, maximum directional stability and exemplary comfort characteristics.

Servotronic as standard, variable sports steering as an option

The new BMW 4-Series Gran Coupé features as standard EPS Electric Power Steering including a Servotronic function. The system provides speed-sensitive power assistance and the clearly defined mapping results in sharper steering feel and feedback. The new BMW 4-Series Gran Coupé can be equipped with variable sports steering as an option. This uses different steering ratios depending on the amount of lock applied. Only a small amount of steering effort is required for maneuvering, for example, while unbeatable tracking and straightline stability at high speeds are guaranteed.

High-performance and lightweight brake system

The new BMW 4-Series Gran Coupé comes equipped with powerful swing-caliper or fixed-caliper brakes and large, inner-vented brake discs. The calipers on the front axle are made of aluminum. As well as boasting low unsprung masses, the brakes also stand out with their superior heat tolerance, excellent wet braking performance, ease of use and excellent feel. A brake pad wear indicator and the Brake Drying function are standard on all models.

Intelligent lightweight construction: reduced weight, maximum stability

The weight optimization of all components significantly influences the dynamic performance of the new BMW 4-Series Gran Coupé. Intelligent lightweight design, a complex bodywork construction and the innovative strut concept all provide a level of body stiffness that is on par with that of the two-door model variant. This is why the four-door Gran Coupé impresses with unmatched levels of agility and precision. The use of high-strength and extra-high-strength multi-phase steel as well as tailored blanks – customized precision components for specific applications – maximizes the degree of stability at an optimized weight. Crucial, stiffness-enhancing components are made of micro-alloyed steel. As a result, the BMW 4-Series Gran Coupé features an extremely torsion resistant body that matches that of the two-door model variant.

Aerodynamics: clever detail solutions for reducing consumption

The reduction of air resistance enhances driving dynamics and reduces consumption. Optimization measures on the front apron and at the rear as well as the streamlined, smooth-surfaced underbody help the new BMW 4-Series Gran Coupé achieve a remarkable aerodynamic drag coefficient (Cd) of 0.274. For example, the BMW Air Curtains in the front apron generate a veil of air that reduces turbulence – and therefore drag – around the front wheels. In order to further optimize driving dynamics, the new BMW 4-Series Gran Coupé features aerodynamically designed wheel arches and air lips positioned in front of them. The Air Breathers positioned rearwards of the front wheel arches divert some of the air flowing through the wheel arches, thereby reducing air resistance.

Adaptive suspension, M Sport suspension and M Sport brakes

An M Sport suspension with a firmer spring/damper set-up and more robust stabilizers for the front and rear axles is available as an option for the new BMW 4-Series Gran Coupé, and can also be ordered separately from the M Sport package. 18-inch or 19-inch M light alloys are also included in this particular case. Alternatively, customers may prefer to specify adaptive suspension – with its focused sporting set-up and electronically controlled dampers – which adjusts the damper mapping to the road surface and driving situation at hand. Moreover, BMW offers an extra-light M Sport brake system for the new Gran Coupé. The team of aluminum fixed calipers (four-piston at the front, two-piston at the rear) and generously sized discs provide ideal preconditions for very short stopping distances.

Sportier, more comfortable or more efficient at the push of a button

In addition to superior driving dynamics, the new BMW 4-Series Gran Coupé convinces with a high level of motoring comfort. Using the ECO PRO mode, the driver can change the vehicle’s overall characteristic according to each driving situation or personal preference to either a sporty or comfortable setting. Accelerator pedal progression, engine response, power steering characteristics and response thresholds of DSC Dynamic Stability Control are influenced by this. The system also interacts with the Steptronic transmission and the optional Dynamic Damper Control. Drivers can select their desired mode – ECO PRO, COMFORT, SPORT or even SPORT+ when they opted for at least one of the following options: 8-speed sport Steptronic transmission, M Sport package, Sport Line, adaptive M suspension or variable sports steering. Each of these predefined set-ups activates different settings for the relevant powertrain and suspension components.

BMW EfficientDynamics: better performance, better fuel economy

Impressive performance coupled with exemplary efficiency is based on the BMW EfficientDynamics development strategy, the results of which are implemented in almost all areas on the BMW 4-Series Gran Coupé. The optimized fuel economy of the petrol and diesel engines, transmissions delivering a high level of efficiency, the intelligent lightweight construction concept, honed aerodynamics and other efficiency-enhancing technologies incorporated into the new BMW 4-Series Gran Coupé all help to optimize driving dynamics, whilst at the same time reducing consumption and emissions.

Package of measures to consistently reduce emissions and increase the pleasure of driving

The new BMW 4-Series Gran Coupé features as standard an Auto Start Stop function to bring about additional economy advantages. Brake Energy Regeneration, which is also a standard feature, ensures that the generation of electric current for the onboard electrical systems concentrates on the overrun and braking phases. ECO PRO mode in particular helps the driver of the new BMW 4-Series Gran Coupé to achieve the best possible fuel efficiency. ECO PRO influences the engine control unit and the characteristic curve of the accelerator pedal. In addition, it contributes to intelligent energy and climate management. The driver is also provided with tips on how to reduce energy consumption even further for the best possible motoring efficiency.

In conjunction with the Steptronic transmission, the new BMW 4-Series Gran Coupé also features a coasting mode. At speeds of between 50 and 160 km/h (31 and 99 mph), in ECO PRO mode, the drivetrain is disconnected as soon as the driver lifts his/her foot from the accelerator pedal. As a result, the BMW 4-Series Gran Coupé vehicle is able to ‘sail’ without engine power, thereby also achieving maximum fuel efficiency. In conjunction with the optional Navigation System Professional, the driver is supported, if desired, by the anticipation assistant. This system provides timely information on the road ahead at an early stage and takes into account speed limits, bends in the road, built up areas and roundabouts. On the basis of this data, the system can give the driver tips on fuel-efficient driving and adjust the shift program of the automatic transmission accordingly.

The ancillary units are also incorporated into the intelligent energy management system of the new BMW 4-Series Gran Coupé. Examples include the demand-controlled coolant pump, the map-controlled oil pump as well as electromechanical power steering, whose electric motor only uses energy when power steering is required. The same is true for the disengageable air-conditioning compressor which reduces the system’s power loss to a minimum.

Intelligent lightweight construction reduces consumption and CO2 emissions

Systematic lightweight construction plays a major part in increasing efficiency and agility. This concept is applied in all areas of development and comprises all components. The targeted utilization of plastics, state-of-the-art composites and the increased deployment of aluminum components in the manufacture of engines and suspensions have helped reduce the weight of the corresponding assembly groups. All these measures have a very positive effect on the BMW 4-Series Gran Coupé’s driving dynamics.

BMW ConnectedDrive

The networking of driver, vehicle and the outside world with new assistance systems and information and entertainment features is increasingly enhancing safety and comfort within the vehicle. BMW was early in recognizing the significance of networking and began integrating the digital world in its cars many years ago. The BMW ConnectedDrive systems offered in the BMW 4-Series Gran Coupé either as standard or as an optional extra underline the technological leadership. The extraordinarily high level of development in mobile automotive communication is reflected in the fact that even after purchasing a BMW, customers can, for a limited period of time, flexibly order and subscribe to a wide range of technologies and services.

Navigation System Professional: operation with touch controller

The latest generation of the Navigation System Professional has a significantly greater breadth of functionality and a high-resolution, contrast-rich, color display. The graphics of the previous user interface have been completely revised and the navigation system’s maps now have 3D elements. The central Control Display is operated in the familiar way using the ergonomically perfectly positioned iDrive touch controller in the center console, which now has an integral new, touch-sensitive surface and proximity sensor technology for even more convenient use. Users can use their finger to write characters or to enter destinations in the navigation system. They can now choose between using their handwriting or conventionally entering the destinations by rotating and pressing the controller.

Head-Up Display: full-color, high-resolution

In the BMW 4-Series Gran Coupé, all information relevant to the driver is presented by the Head-Up Display directly in the driver’s line of vision. The information from the assistance systems, the navigation system or information pertaining to speed is projected onto the windscreen in a particularly brilliant resolution using the full color spectrum. The wide variety of driver assistance systems now available brings the amount of information that can be shown in the Head-Up Display to a whole new level.

Real Time Traffic Information: the smart way to avoid congestion

The quality of traffic management depends on the quality and currentness of traffic data available. The optional RTTI (Real Time Traffic Information) system from BMW transmits data fast and accurately via the mobile phone network. A SIM card integrated in the vehicle receives traffic data in real time and then calculates routes or detours instantly. RTTI covers motorways and dual carriageways, as well as country roads and main and side roads in urban areas. Data is additionally obtained from local authority traffic management systems to provide precise information on traffic density.

Driving Assistant warns the driver of potential collisions – including those involving pedestrians

The Driving Assistant Plus uses intelligently networked camera-based assistant systems and image processing to detect any people or vehicles within its field of vision. The movements of pedestrians are difficult to anticipate – they stop or suddenly change direction. Therefore, they impose much higher demands on the detection capabilities of assistant systems than vehicles driving ahead. When the system recognizes a looming risk of collision, it produces an acute audible warning and a visual signal appears in the instrument cluster or the Head-Up Display to alert the driver that he or she is drawing too close. The system ideally avoids a collision or, should the worst come to the worst, significantly reduces the consequences of an impact.

Active Cruise Control with Stop & Go function: a system of many talents

More active safety and more comfort are provided by the latest version of BMW’s Active Cruise Control with Stop & Go function (ACC Stop&Go). It uses the data provided by the full-range radar sensors, continuously measures the proximity of the vehicle ahead and warns the BMW driver if necessary. Active Cruise Control with automatic distance control is now available at speeds between 30 km/h and 210 km/h (approx. 18 and 130 mph).

Lane Change and Lane Departure Warning systems use sensors and camera monitoring

Lane Change Warning and Lane Departure Warning are convenience and safety-enhancing assistance systems. These systems employ radar sensors and use the data from the front camera to alert drivers to potential collision risks when changing lanes or if they veer out of lane unintentionally and also issue a warning when driving too close to the vehicle ahead. The Lane Departure Warning system is only available as part of the Driving Assistant option.

Speed Limit Info: always up to date

In conjunction with the Navigation System Professional and the Navigation System Business, Speed Limit Info helps to keep the driver informed of the speed limit for the current stretch of road. The front-mounted camera ensures that additional signs or variable overhead gantry signs are taken into account. In addition, the system is able to reliably identify and react to temporary speed limits. When the window wipers are active, the system also detects signs that are valid in wet conditions only. In conjunction with the exact onboard time, speed limits are presented which are only in force at certain times of day or night.

Improved sight at night: full LED headlights with glare-free High Beam Assistant

The bright white light emitted by full LED headlights illuminates the road ahead with an exceptional intensity. With high beam activated, the High Beam Assistant partially masks the headlights as required in order to eliminate the danger of dazzling vehicles as they approach. The High Beam Assistant can also adapt to the traffic situation by switching to low beam on one or both sides. In conjunction with the front camera, the system reliably detects well lit stretches of road and switches to low beam when passing through cities, for example. The LED headlights with glare-free High Beam Assistant significantly increase the usage of high beam and therefore provide for better sight and increased safety when driving at night. When full LED headlights are fitted, the optional fog lights are also implemented in LED technology, which further accentuates the premium character of the car’s features and equipment.

Superb overview and convenient parking

In addition to the rear view camera and PDC Park Distance Control, customers can also opt for the Surround View function with Side View and TopView, which provides a bird’s eye view of the BMW 4-Series Gran Coupé and the area around it, enabling the driver to carry out precise maneuvers in tight spaces. If the car is moving at under 20 km/h (approx. 12 mph), the Side View function can additionally be activated to allow the driver to keep an eye on cross traffic. Convenience is further enhanced by the BMW Parking Assistant system which is able to maneuver the car into parking spaces parallel to the direction of travel. Ultrasound sensors detect possible parking spaces while driving by and the system perfectly maneuvers the car into the parking spot if desired. All the driver has to do is to change between the forward and reverse gear, use the accelerator and the brake pedal, respectively. This way he or she can fully focus on the parking process.

Active Protection: increased safety in all situations

The Active Protection safety package with extended protection measures and the Emergency Call function with automatic vehicle location help to mitigate the consequences of an accident, should the worst come to the worst. Active Protection is activated shortly after the journey begins, ready to pull the driver and front passenger belts tight and close the side windows if the car enters a critical pre-crash scenario. If the system detects an impending collision and senses that a crash is unavoidable, the car will be decelerated automatically and held at a standstill with its brakes locked. This significantly reduces the likelihood of – or entirely forestalls – a second collision. The Active Protection safety package is now even more extensive thanks to the addition of the Attentiveness Assistant. The system’s electronics analyze driving behavior on the basis of various onboard signals. If the system detects an increased frequency in the tell-tale signs of fatigue build-up, the Control Display prompts the driver to take a break by displaying a coffee cup symbol.

Services and apps: innovative services and infotainment in its purest form

Due to the ever-increasing popularity of smartphones and other digital devices, Internet, apps and digital services have been an integral of everyday life for some time now. BMW ConnectedDrive offers high-performance interface technology and provides top-of-the-range infotainment and entertainment capability that enables the driver and passengers to make extensive use of external mobile phones and music players. Through the optional ConnectedDrive Services, the world of apps can be integrated into the vehicle. Browser-based BMW online applications are loaded directly into the vehicle via an embedded onboard SIM card. These applications put at the driver’s disposal online services such as weather, news or office functions. Smartphone apps allow in-car use of innovative services like Audible, Aupeo!, Deezer, Twitter or Facebook.

The latest-generation Navigation System Professional features a full speech recognition function and an optimized voice control system to complete the portfolio of office functions offered by BMW ConnectedDrive. The full speech recognition system enables drivers to dictate text freely and compose short text-based messages by voice. In addition, Internet-based services, as well as calendar entries and text-based messages, can still be viewed in the Control Display of the iDrive operating system and read out via the Text to Speech function.
