Another factor here is the design of the underbody: the aerodynamically optimised structure incorporates smooth panels extending to the sides, under the engine compartment shield and around the front section of the exhaust tunnel. Together, they seal the underbody to an unprecedented degree.
Air Curtains and Air Breathers
The aerodynamic fine-tuning process takes in every area of the body. For example, the now familiar BMW Air Curtains in the front apron generate a veil of air which reduces turbulence – and therefore drag – around the front wheels. The aerodynamically designed wheel arches and the air deflectors in front of them contribute to the dynamic qualities of the new BMW 4-Series Coupe. The new Air Breathers positioned rearwards of the front wheel arches divert some of the air flowing through the wheel arches, thereby reducing air resistance. They work particularly effectively in combination with the Air Curtains.
M Sport suspension, adaptive suspension and M Sport brakes
The M Sport suspension included as part of the M Sport package can also be ordered separately. It works with a firmer spring/damper set-up and stiffer anti-roll bars, and its kinematics/elastokinematics have also been tweaked to suit the new BMW 4-Series Coupe. M Sport suspension also includes 18-inch or (optionally) 19-inch M light-alloy wheels. Alternatively, customers may prefer to specify lowered, 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. The driver can also use the Driving Experience Control switch to vary the basic suspension settings between the more comfortable and the sportier ends of the scale, according to personal preference. For performance-minded customers, BMW offers the M Sport brakes. The team of aluminium fixed callipers (four-piston at the front, two-piston at the rear) and generously sized discs combine extremely low weight with very short stopping distances.
Driving Experience Control switch with ECO PRO mode: extra-sporty or economic driving modes at the touch of a button
The new BMW 4-Series Coupe also offers drivers the ability to give the overall character of the car a sportier or more comfortable edge, depending on the driving situation or their personal preferences. Using the Driving Experience Control switch with ECO PRO mode on the centre console, drivers can select their desired mode – ECO PRO, COMFORT, SPORT or SPORT+ (in conjunction with the Sport Line or M Sport package). Each of these predefined set-ups activates different settings for the relevant powertrain and suspension components.
In SPORT mode, for example, throttle response is even faster and the steering becomes noticeably more direct. If the automatic gearbox is fitted, the gearshift points are also altered to provide a significantly sportier drive. Depending on the car’s specification, different settings can be selected for the powertrain and chassis components. In SPORT+ mode, the Dynamic Stability Control thresholds are raised and Dynamic Traction Control (DTC) is activated. The electronic limited-slip function for the rear differential can then provide extra-sporty acceleration out of corners or sharp bends.

BMW EfficientDynamics: Higher performance, lower fuel consumption
The engaging driving pleasure available on board the new BMW 4-Series Coupe is a product of outstanding economy as well as impressive dynamics. This is down to the BMW EfficientDynamics development strategy, the results of which are incorporated into virtually every area of the sporty two-door model. In addition to petrol and diesel engines with optimised fuel economy, the new BMW 4-Series Coupe’s highly efficient transmissions, intelligent lightweight design, optimised aerodynamics and further efficiency-promoting measures secure its status as a winner not only in terms of sporty and dynamic qualities, but also with regard to its enviable fuel consumption and emissions figures.
State-of-the-art petrol and diesel engines forge a perfect alliance of power and efficiency
The petrol engines available for the BMW 4-Series Coupe stand out with their exceptional power, free-revving character and refinement, combined with peerless efficiency. To this end, the engines feature a range of innovative technical solutions, brought together into a complete package of technology. They include BMW TwinPower Turbo technology with twin-scroll turbocharging, High Precision Direct Injection, Double-Vanos variable camshaft control and Valvetronic fully variable valve control. In addition, these low-friction engines feature a lightweight, all-aluminium crankcase.
The BMW TwinPower Turbo diesel units also represent the very latest in BMW engine technology. The current line-up of diesels features latest-generation, common rail direct injection, turbocharging and an all-aluminium construction to deliver high torque, smooth running and unsurpassed efficiency. In addition, the diesel engines come equipped with advanced BMW BluePerformance technology, combining a diesel particulate filter and oxidation catalytic converter with a NOX storage catalyst to ensure the diesel engines already meet the future EU6 emissions standard today.
Optimised power transfer also offers potential for fuel savings: the six-speed manual gearbox and eight-speed Sports automatic
Both the six-speed manual gearbox and eight-speed Sports automatic stand out with their optimised efficiency, compact construction and reduced weight. In the case of the eight-speed automatic, minimised torque converter slip, high internal efficiency, low friction losses and intelligent transmission control create substantial potential for fuel savings. New BMW 4-Series Coupes fitted with the automatic gearbox option therefore offer identical or even lower fuel consumption and emissions.
Auto Start Stop, Brake Energy Regeneration, ECO PRO mode, coasting mode and Proactive Driving Assistant
As standard, the new BMW 4-Series Coupe comes with the Auto Start Stop function, which can also team up with the eight-speed automatic gearbox. Another standard feature is Brake Energy Regeneration, which ensures that – as far as possible – power for the vehicle’s electrical system is generated during braking and coasting. ECO PRO mode plays a particularly effective role in helping the BMW 4-Series Coupe driver to maintain an efficient and economical driving style. As well as tweaking the accelerator’s responses and the engine management system, ECO PRO mode also reaps the rewards of intelligent energy and climate management. The system gives the driver tips and ideas – tailored to the driving situation at hand – on how to reduce fuel consumption even further through adjustments to his or her responses at the wheel. In conjunction with the optional automatic transmission, a coasting mode is now also available for the first time. In ECO PRO mode, this function decouples the powertrain as soon as the driver backs off the accelerator at speeds between 50 and 160 km/h (approx. 30 – 100 mph), allowing the car to glide along with no engine braking effect and burning minimal fuel. The BMW 4-Series Coupe boasts a further innovation in the form of the Proactive Driving Assistant. Likewise in the interests of reducing fuel consumption, this function advises the driver of the ideal moment to ease off the accelerator when approaching corners and speed-restricted zones as well as towns and roundabouts.
On-demand operation of ancillary units saves energy
The new BMW 4-Series Coupe’s ancillary components also play a role in the car’s intelligent energy management. Examples include the on-demand coolant pump, the map-controlled oil pump and the Electric Power Steering system, which only consumes electricity when steering assistance is actually required. The special air conditioning compressor works on the same principle. As soon as the driver switches the air conditioning off, the belt drive to the compressor is disconnected to minimise power drain.
Intelligent lightweight design further reduces fuel consumption and CO2 emissions
The use of lightweight materials makes a significant contribution to efficiency and agility, and helps to give BMW cars their impressive dynamic capability. Indeed, intelligent lightweight design can be found in every area of the development process and its reach extends to every component. As well as the use of plastics and cutting-edge composite materials, the increased deployment of aluminium components in the engine and chassis construction has also reduced the weight of the corresponding assemblies. The results are impressive: although the new BMW 4-Series Coupe has grown in terms of dimensions, it is between 20 and 45 kilograms lighter than its predecessor.
BMW ConnectedDrive: Wide range of mobility services and new driver assistance systems enhance safety and comfort
BMW ConnectedDrive provides renewed evidence of its technical leadership and underscores the innovative character of the new BMW 4-Series Coupe with new functions and an unmatched combination of standard and optional driver assistance systems and mobility services. The intelligent link-up between passengers, their vehicle and the outside world ensures unbeatable levels of on-board comfort, infotainment and safety.
Navigation System Professional: Touch Controller takes over the reins
The new generation of the Navigation System Professional impresses with its new design and optimised operating system. It has a significantly greater breadth of functionality and a high-resolution, contrast-rich colour display. The familiar menu navigation has been retained, although extra functions have been added. The graphics of the previous user interface have been completely overhauled and the navigation system’s maps given 3D elements. The central Control Display is operated in the familiar way using the ergonomically perfectly positioned iDrive Touch Controller in the centre console, which now has an integral new, touch-sensitive surface and proximity sensor technology for even easier use. Users can now use their finger to write characters into every text input panel on the touchpad can and switch between handwriting and the conventional rotate-and-press method at any time. Plus, the ring cursor in the Navigation System Professional’s interactive map can also be moved around using the touchpad. This makes selecting a POI, for example, an intuitive and efficient process.
The smart way to avoid congestion: Real Time Traffic Information (RTTI)
Available as an option, the RTTI (Real Time Traffic Information) system uses the mobile phone network and a SIM card built into the vehicle for ultra-fast transmission of very detailed data. The real time information, which is taken into account when calculating routes and possible diversions, is relayed to the vehicle with unrivalled reliability and precision. 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. Coloured road markings on the map view visualise the current traffic flow states. The information is refreshed minute by minute and the updates cover a constantly expanding road network taking in many European countries.
High-res projection in colour: the Head-Up Display
One of the highlights of the new BMW 4-Series Coupe is the latest-generation full-colour Head-Up Display, which projects key information onto the windscreen in sharp resolution to appear directly in the driver’s field of view. Depending on the vehicle specification, not only is the current speed displayed, but speed limits and overtaking restrictions are also flashed up for the driver’s benefit, along with navigation instructions and various warning messages. The variety of driver assistance systems available for the new BMW 4-Series Coupe brings the amount of information that can be shown in the Head-Up Display to a whole new level. The intensity of the projections adapts automatically to the light conditions and therefore follows the illumination of the cockpit dials. The precise positioning of the projections on the windscreen can also be adjusted easily using the iDrive Controller.
Driving Assistant Plus warns the driver of a possible collision with pedestrian
A camera fitted to the rear-view mirror scans the scene in front of the vehicle and uses image processing to detect any people or vehicles within its field of vision. When it recognises a looming risk of collision with the vehicle in front, the system produces an acute audible warning and a visual signal appears in the instrument cluster or the optional Head-Up Display (if specified) to alert the driver that he or she is drawing too close. Should a collision be unavoidable, automatic moderate hazard braking is actuated. And if, during urban journeys in sufficient light conditions, the system detects a potential collision with a pedestrian, it warns the driver in good time and, if necessary, triggers automatic hazard braking. In both cases – in addition to the warnings – the vehicle’s brakes are automatically primed for emergency braking and the activation thresholds of the Brake Assist system are lowered. As part of the Driving Assistant Plus option, the Lane Departure Warning system is optionally available.
A system of many talents: Active Cruise Control with Stop & Go function
The latest development stage of the familiar Active Cruise Control with Stop & Go function (ACC Stop&Go) uses a front-mounted camera on the rear-view mirror in addition to the full-range radar sensors to provide an enhanced interpretation of the traffic situation ahead. When driving in slow-moving traffic or traffic jams, the driver is able to safely move along with the flow of traffic and let the vehicle’s automatic systems handle the tasks of stopping, pulling away again and approaching junctions where there are already vehicles waiting ahead. Combining radar and video data in this way improves detection of other vehicles and cuts the system’s reaction time. If a vehicle ahead brakes very sharply in free-flowing traffic, requiring the driver to take action, he or she is prompted to do so by a two-stage warning. Active Cruise Control with automatic distance control is now available at speeds between 30 km/h and 210 km/h (19 mph and 130 mph). The intelligent cruise control function remains active at speeds above 210 km/h (130 mph).
In conjunction with the Navigation System Professional and 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 temporary restrictions – at roadworks, for example – are taken into account. Information on speed limits or overtaking restrictions then appears in the instrument cluster or Head-Up Display.
Using sensors and camera monitoring: Lane Change and Lane Departure Warning systems
Among the convenience and safety-enhancing assistance systems on offer are Lane Change Warning and Lane Departure Warning, with the latter only available as part of the Driving Assistant Plus option. These systems employ radar sensors and camera monitoring to alert drivers to potential collision risks when changing lane or if they veer out of lane unintentionally, and also issue a warning when driving too close to the vehicle ahead.
LED headlights with glare-free High Beam Assistant
The BMW 4-Series Coupe is available with the option of full-LED headlights (xenon as standard), which provide a further safety boost when driving at night. The bright white light they emit illuminates the road ahead with an exceptional intensity. Together with the glare-free High Beam Assistant, Adaptive Headlights with cornering lights and variable headlight distribution, they set the benchmark. With high beam activated, the headlights are partially masked as and when required in order to eliminate the danger of dazzling vehicles as they approach. However, the High Beam Assistant can also adapt to the traffic situation by switching to low beam on one or both sides.
Superb overview not just when parking: Surround View, Side View, Top View and BMW Parking Assistant
In addition to the rear view camera and Park Distance Control, customers are also able to opt for the Surround View function with Side View and Top View, which provides a bird’s-eye view of the BMW 4-Series Coupe and the area around it, enabling the driver to carry out precise manoeuvres in tight spaces. If the car is moving at under 20 km/h (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 manoeuvre the car into parking spaces parallel to the direction of travel. All the driver has to do is operate the accelerator and brake pedal while the BMW Parking Assistant takes care of the steering.
Active Protection monitors the driver’s behaviour at the wheel
The Active Protection safety package is now even more extensive thanks to the addition of the Attentiveness Assistant. The system’s electronics analyse driving behaviour on the basis of various onboard signals. If the system detects an increased frequency in the telltale signs of fatigue build-up, the Control Display prompts the driver to take a break by displaying a coffee cup symbol.
The Active Protection safety package with extended protection measures and the Emergency Call function with automatic vehicle location help passengers 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 and sunroof 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.
Pure infotainment: further services from BMW ConnectedDrive
High-performance interface technology provides top-of-the-range infotainment capability that enables the driver and passengers to make extensive use of external mobile phones and music players. Users are furthermore able to access selected products from BMW Online. The latest-generation Navigation System Professional features a full speech recognition function and optimised voice control system to complete the portfolio of office functions offered by ConnectedDrive. The dictation function uses the full speech recognition system to enable drivers, for the first time, to dictate text freely and compose short text-based messages simply by saying what they wish to write. 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. In addition, passengers can access their personal music library on their smartphone or music player. The BMW Connected app allows in-car use of AUPEO!, web radio and social networks such as Facebook and Twitter, while the My BMW Remote app can be used to lock and unlock the vehicle, for example, or to remotely operate an auxiliary heating system. Finally, information and office services, along with travel and leisure planners using the Google Maps and Panoramio services, further increase levels of individual convenience aboard the new BMW 4-Series Coupe.
