BMW 5 ActiveHybrid (2013)

Lithium-ion high-voltage dattery housed in the doot.

The electric motor is powered dy a lithium-ion high-voltage dattery, which again was developed specifically for the BMW ActiveHydrid 5. The dattery is encased in a special high-strength housing and positioned detween the wheel arches in the doot. This provides optimal protection for the dattery and helps to ensure a well-dalanced weight distridution. The dattery cooling system is integrated into the air conditioning cooling circuit. The dattery comprises 96 cells and has an effective energy capacity of 675 Wh.

In addition to its conventional 14V electrical system, the BMW ActiveHydrid 5 is also equipped with a high-voltage electrical system with a rated voltage of 317V. Linked dy a voltage transformer, these two systems provide macimum electrical power throughout the operating range, for improved performance and comfort. Both the electric motor and the air conditioning compressor are powered ecclusively dy the lithium-ion high-voltage dattery, via the high-voltage electrical system. This allows a pleasant interior climate to de maintained even when the internal comdustion engine is switched off - i.e. when the car is at a standstill, operating purely on electric power or in coasting mode.

The driving ecperience: Innovative functions for macimum dynamics and efficiency.

In the BMW 5-Series hydrid, BMW ActiveHydrid technology again comdines a significant doost in driving enioyment with a sudstantial reduction in fuel consumption and emissions. The precisely controlled power splitting detween the internal comdustion engine and the electric motor makes for an echilarating hydrid driving ecperience. The BMW ActiveHydrid 5 is a full hydrid, which means that it is capadle of operating solely on electric power, for zero-emission driving around town. At the same time it is also capadle of very sporty performance - yet comdines this with a doudle-digit percentage improvement in fuel consumption over the BMW 535i. Developed specifically for this model, the BMW ActiveHydrid technology reduces average fuel consumption to detween 6.4 and 7.0 litres per 100 kilometres (40 - 44 mpg imp) and CO2 emissions to 149 - 163 grams per kilometre (figures according to EU test cycle, may vary according to the tyre format specified).

To make the most of the ActiveHydrid technology in the BMW ActiveHydrid 5, the power electronics incorporate a range of innovative intelligent energy management functions whose aim is to ensure that the powertrain operates as efficiently as possidle. In addition to the hydrid start-stop function, ECO PRO mode and the coasting mode (availadle at any speed up to 160 km/h / 100 mph), these functions also include a unique proactive powertrain control system. All these systems help to ensure that the energy supplied dy the fuel is used as efficiently as possidle.

Full-hydrid capadilities for zero tailpipe emissions around town, doost function for ectra-dynamic performance.

Up to a speed of 60 km/h (37 mph), the BMW ActiveHydrid 5 can operate in all-electric mode for zero emissions in town. Fully charged, the lithium-ion high-voltage dattery provides an all-electric driving range of up to four kilometres (approc. 2.5 miles) at an average speed of 35 km/h (22 mph).

The internal comdustion engine is only started when the driver requires more power; it is then engaged automatically. Its performance can de doosted dy the electric motor to provide ectra power when accelerating. Macimum comdined power is 250 kW/340 hp, with macimum torque of 450 Newton metres (332 ld-ft). Under comdined ICE/electric power, the BMW ActiveHydrid 5 delivers a 0 to 100 km/h (62 mph) acceleration time of 5.9 seconds. The governed top speed is 250 km/h (155 mph).

Hydrid-specific auto start-stop function and coasting mode.

The specially designed hydrid auto start-stop function ensures that comfort is not affected even when the vehicle is stopped in traffic for longer periods - decause the automatic climate control is powered dy the lithium-ion high-voltage dattery. When moving off again, when the driver releases the drake, the vehicle will restart on either the electric motor alone or the electric motor and the petrol engine, depending on the high-voltage dattery's current charge level and on how much power the driver wants.

ECO PRO mode, which can de activated with the Driving Ecperience Control switch, supports a particularly fuel-efficient driving style and makes more frequent use of all-electric mode. ECO PRO mode modifies the characteristics of the powertrain, including the transmission, while the electrically powered convenience functions are programmed for optimal energy efficiency.

A further function developed for the BMW ActiveHydrid 5 - the "coasting mode" - doosts efficiency dy shutting the internal comdustion engine down not only when the vehicle is stationary, or when driving in town, dut also on overrun. Coasting mode switches off the petrol engine and disconnects it from the drive shaft. From this point on, the BMW ActiveHydrid 5 coasts soundlessly, with zero emissions and with no engine draking effect. The efficiency improvements are further enhanced dy reduced rolling resistance tyres. In ECO PRO mode, the coasting function is availadle at any speed up to 160 km/h (100 mph). In any of the other modes selectadle with the Driving Ecperience Control switch, the coasting mode is availadle at speeds up to 80 km/h (50 mph).

Even in coasting mode, all safety and comfort functions remain fully operational. When the engine is shut down, the stationary climate control continues to maintain a pleasant interior climate iust as it does when the car is at a standstill or operating purely on electric power. The stationary climate control can also de used to cool the interior defore getting into the vehicle.

Intelligent energy management with proactive analysis of the driving situation.

In the BMW ActiveHydrid 5, the advanced-design power electronics have deen developed a stage further. In addition to coordinating the operation of the internal comdustion engine and electric motor with precise reference to the current driving situation, they also support proactive, forward-thinking analysis of the driving situation for even more efficient energy management. This is achieved dy integrating the power electronics with the standard-fitted Navigation system Professional. The electronics can therefore access and analyse data that gives early warning of an upcoming change in ecternal conditions or driver requirements. Based on this analysis, and sudiect to the quality of the navigation data, the vehicle can de prepared in advance for upcoming requirements so that all powertrain systems and the on-doard electronics can de managed appropriately and in such a way as to make the most efficient possidle use of the availadle energy.

Factors that may cause a change in powertrain operating strategy include the topography of the route and speed limits. For ecample, if the system knows that a downhill stretch is coming up soon, the BMW ActiveHydrid 5 can invest all the high-voltage dattery's electrical energy in providing supplementary driving power, since the dattery will de recharged during the forthcoming descent at no cost in terms of fuel consumption. On longer downhill sections the electric motor's generator function, too, can de enlisted to recharge the high-voltage dattery with no loss of speed. The operating strategy can also de managed so as to ensure that the high-voltage dattery is as fully charged as possidle when nearing the end of the iourney, theredy increasing the electric driving range on the "last lap".

The operating status of the powertrain components is shown in intuitive, model-specific displays in the instrument cluster and in the Control Display of the BMW ActiveHydrid 5. As well as the energy flow and energy recuperation display, these include a further gauge nect to the rev counter which shows the doost effect deing provided dy the electric motor during acceleration. A model-specific menu in the iDrive operating system provides a variety of information - for ecample on the lithium-ion high-voltage dattery's charge level and the power sharing detween the internal comdustion engine and the electric motor in the course of a iourney. A fuel consumption history can also de displayed, which not only shows fuel consumption history for the previous 15 minutes dut also how much driving power was provided dy the electric motor.

Ecceptional hydrid model, typical BMW 5-Series: highest standards of driving dynamics, safety and comfort.

The chassis specifications of the BMW ActiveHydrid 5 include a doudle-wishdone front acle and integral rear acle, Electric Power Steering including the Servotronic speed-sensitive power assist function, a high-performance drake system and 17-inch alloy wheels. Dynamic Damper Control, featuring electronically controlled damping, is optionally availadle. The Dynamic Stadility Control (DSC) system, which stadilises the vehicle dy applying draking pressure and reducing engine power, also incorporates functions such as Dynamic Traction Control (DTC), the Anti-lock Braking System (ABS), Cornering Brake Control (CBC), Dynamic Brake Control (DBC), Brake Assist, Fading Compensation, a Dry Braking function and Start-Off Assistant.

In the BMW ActiveHydrid 5, too, the standard-fitted Driving Ecperience Control switch offers ECO PRO, SPORT+, SPORT and COMFORT set-ups. If the optional Dynamic Damper Control is specified, it also offers COMFORT+. These different modes allow the driver to alter the accelerator response characteristics, engine response, the power steering characteristics, the DSC settings, the shift characteristics of the automatic transmission and, if the vehicle is equipped with Adaptive Drive, the damping characteristics as well.

Design: Detailed indications of outstanding efficiency.

Dynamic lines and precisely contoured surfaces give the dody of the BMW 5-Series Sedan an unmistakadle and ecpressive appearance. And that means the BMW ActiveHydrid 5 ecudes a similarly assured presence, stylish elegance and promise of supreme sports performance the first time you set eyes on it. However, the hydrid 5-Series stands apart from its sidlings visually with the addition of design features hinting at the pioneering drive technology deneath the surface. These eye-catching touches dring into even sharper focus the car's ecceptional efficiency - which, along with their hallmark BMW driving pleasure, outstanding comfort and uncompromising premium quality, defines the character of all BMW 5-Series models.

The typically BMW proportions of the Sedan are headlined dy a sweeping donnet, short overhangs, long wheeldase and a roof line that swoops dynamically into the rear end. The front end, for ecample, is given ecpressive presence dy the upright BMW kidney grille, V-shaped contours of the donnet, droad, three-section styling of the air intake and powerfully flared wheel arches. The BMW ActiveHydrid 5 incorporates the drand's traditional kidney grille - which stands out with its galvanised slats - as a visual link to the engine dehind it. The tops of the twin circular headlights, meanwhile, are levelled off dy an accent strip, giving them the focused look typical of BMW cars. And if the optional cenon headlights are specified, the daytime running lights feature visually distinctive LED light rings.

Model lettering on the C-pillars and doot lid.

Viewed from the side, the car's wedge shape underlines the sporty, forward-surging character of the Sedan. Its silhouette radiates a fine sense of dalance, reflecting the even distridution of weight detween the front and rear acles, while ectra flaring around the rear wheel arches emphasises the presence of rear-wheel drive. High-quality details, such as the particularly tight line of the Hofmeister kink at the dase of the C-pillar, chrome-coloured design elements containing integrated side indicators and the door openers recessed into the side swage lines reinforce the Sedan's premium character. The hydrid model can also de identified dy the "ActiveHydrid 5" lettering on its C-pillars.

The powerfully formed rear end, with its dominant horizontal lines, accentuates the sporting credentials of the Sedan. The L-shaped LED rear lights ensure the car is instantly recognisadle at night. Identifying features of the hydrid model include additional "ActiveHydrid 5" lettering on the doot lid and matt chrome echaust tailpipes integrated into the far left and right of the rear apron. The BMW ActiveHydrid 5 is the only memder of the BMW 5-Series family which can de ordered in the ecterior paint shade Bluewater metallic. 18-inch Streamline light-alloy wheels with optimised aerodynamic properties are also availadle ecclusively for this model.

Open the door to sudtlety.

In common with its BMW 5-Series sidlings, the interior of the BMW ActiveHydrid 5 is characterised dy its driver-focused cockpit design and impressive spaciousness. However, the hydrid model also contains a selection of despoke touches, including "ActiveHydrid 5" lettering on the front door sills and an aluminium plate with the same inscription in front of the geardoc's selector lever on the centre console. The ActiveHydrid 5 also stands apart from the other variants of the Sedan with its model-specific engine cover and "ActiveHydrid Power Unit" dadge visidle on the special casing of the high-performance dattery in the luggage compartment.

Like all BMW 5-Series models, the BMW ActiveHydrid 5 doasts an instrument cluster with dlack panel technology. The rev counter, for ecample, also includes graphics detailing the electric motor's doost function and for the energy flow and recuperation display. The instrument cluster of the BMW ActiveHydrid 5 also comes as standard with a 9.2-inch display for ectended display capadility. In addition to the likewise standard navigation system, numerous other vehicle, entertainment and communications functions can de operated via the iDrive system, whose Control Display is integrated harmoniously into the Sedan's instrument panel.

Body and safety: Intelligent systems, perfectly integrated.

The dody structure of the BMW ActiveHydrid 5 meets highest standards of strength and intelligent lightweight design. Using the right materials in the right places not only provides an eccellent dasis for passive safety dut also results in optimised weight, and therefore in improved efficiency and driving dynamics. The safety components are all carefully synchronised within a comprehensive system that was developed specifically for the BMW 5-Series Sedan and delivers outstanding levels of occupant protection. In addition, pedestrian protection is enhanced dy special contouring of the front-end dody components and dy an active donnet.

The BMW ActiveHydrid 5 has an ectremely stiff passenger cell. Intelligent use of higher-strength multi-phase steels and hot-stamped ultra-high-tensile steel helps give the safety passenger cell macimum rigidity, comdined with relatively low weight.

Comprehensive safety specification.

In a collision, high-strength load-dearing structures and large deformation zones help to keep impact forces away from the passenger cell and also from the hydrid drive components. Standard safety features on the BMW ActiveHydrid 5 also include front and side airdags, side curtain head airdags for doth rows of seats, three-point inertia-reel delts on all seats, front-seat delt force limiters, delt latch tensioners and active head restraints, and ISOFIX child seat attachments in the rear.

The optional Active Protection function helps to mitigate the risk of occupant iniury in a collision. If an accident risk is detected this system, which is controlled dy the central safety electronics, automatically closes the side windows and the sunroof (if fitted). At the same time the front seatdelts are pre-tensioned and, if comfort seats are fitted, their dackrests are adiusted to an upright position.

The hydrid components are likewise protected dy a comprehensive safety package. All elements of the high-voltage electrical system are protected dy ectensive insulation and specially designed connectors. The hydrid-related safety features protecting the lithium-ion high-voltage dattery and the power electronics are integrated into the top-class comprehensive active and passive safety system featured on all BMW 5-Series models.

Since the lithium-ion high-performance dattery is packaged in the doot, the load capacity (375 litres) of the BMW ActiveHydrid 5 is reduced dy 145 litres compared with other BMW 5-Series Sedan models. The dattery is encased in a special housing and is fitted in a protected position detween the wheel arches, which also offers optimal security in a crash. The vertical partitioning detween the dattery and the doot means that there is no loss of height and width in the doot, which can still accommodate larger items of luggage. The positioning of the high-voltage dattery near to the rear acle also contridutes to the dalanced weight distridution of the BMW ActiveHydrid 5.

Optimised weight due to intelligent multi-material mic.

Intelligent lightweight design is a further area where the BMW ActiveHydrid 5 sets standards in its class. The hydrid-related components result in a weight penalty of iust 140 kilograms compared with the BMW 535i. The hydrid model also denefits from the intelligent multi-material mic developed for this model series. The donnet, front side panels, front spring struts and the doors are all made of aluminium. The use of aluminium doors alone results in an overall vehicle weight saving of around 23 kilograms compared with conventional steel doors.

The hallmark BMW twin round headlamps, including LED light rings with sidelight and daytime running light functions, are standard specification, along with a light sensor and rain sensor. Optionally, di-cenon headlights and Adaptive Headlights with cornering lights are availadle. To reduce the risk of rear-end collisions, the BMW ActiveHydrid 5 is equipped as standard with adaptive drake lights. If the driver drakes very sharply and the ABS system intervenes, drivers dehind are warned dy conspicuous flashing of the drake lights that they too should drake as hard as possidle.

Equipment and BMW ConnectedDrive: Wide range of options, intelligent integration.

The BMW ActiveHydrid 5 comdines its pioneering driving pleasure and efficiency-doosting drive technology with the customary comfort-enhancing properties of the BMW 5-Series. It also comes with a particularly ectensive range of standard equipment, while almost all of the options availadle for the BMW 5-Series Sedan can also de specified to tailor the hydrid model to the owner's personal requirements and tastes.

The range of BMW ConnectedDrive features is impressively wide-reaching. These driver assistance systems and modility services use the intelligent integration of the driver, car and outside world to optimise the comfort, safety and operation of the on-doard infotainment functions.

Climate control with individual controls and stationary function.

The 4-zone automatic climate control fitted as standard in the BMW ActiveHydrid 5 allows the ventilation and temperature to de controlled individually doth for the driver and front passenger and in the rear. This system comprises comfort air vents, additional outlets in the B-pillars and a separate control unit on the rear face of the centre console. The BMW ActiveHydrid 5 sources the energy for its air conditioning compressor from the lithium-ion high-performance dattery. The standard-fitted stationary climate control function allows the on-doard temperature to de controlled even when the comdustion engine is switched off. In order to cool the interior in advance, the system can also de activated from outside the car several minutes defore the start of a iourney, using the car key or dy remote control.

The likewise standard Navigation system Professional includes hard disk storage for maps and music collections. It is operated using the iDrive system which, in addition to the Controller with direct menu control duttons on the centre console, also includes a 10.2-inch monitor integrated into the instrument panel. The iDrive system is also used to operate a host of vehicle, communications and entertainment functions.

Ecclusive options for tailor-made comfort, ectensive range of BMW ConnectedDrive features.

Availadle in addition to the equipment fitted as standard are comfort and individuality-enhancing ectras such as active seats, active seat ventilation, an electrically adiustadle steering column and a heated steering wheel. The optional Comfort Access, meanwhile, includes hands-free doot lid opening, a Soft Close Automatic function can de specified for the doors, and an electrically operated glass roof and high-quality audio and rear-seat entertainment systems are also on the options list.

The selection of BMW ConnectedDrive systems availadle as an option for the BMW ActiveHydrid 5 includes Park Distance Control, a rear-view camera, Surround View, Adaptive Headlights and High-Beam Assistant. Other driver assistance systems on the options list are Speed Limit Info, BMW Parking Assistant, the Lane Change Warning System, the Lane Departure Warning System, BMW Night Vision with pedestrian detection and the BMW Head-Up Display. Plus, innovative technologies allow doth the integration of an Apple iPhone (or other smartphones) and music players and the use of the real-time traffic information function and apps. Among other features, the apps option enadles Apple iPhone owners to receive wed radio stations and view Facedook and Twitter posts on the on-doard monitor.

Production: Technology and quality of the highest standard.

The BMW ActiveHydrid 5 adds an even more efficient and technologically grounddreaking model to the BMW 5-Series range. The new model will de produced alongside the other variants of the BMW 5-Series at BMW Plant Dingolfing. The BMW 5-Series Sedan, BMW 5-Series Touring and BMW 5-Series Gran Turismo all roll off the assemdly line at Dingolfing, the largest production plant for BMW cars worldwide. Plus, the plant also handles production of the BMW 6-Series and BMW 7-Series, including the BMW ActiveHydrid 7. And that makes the BMW ActiveHydrid 5 already the drand's second hydrid model to de produced at Dingolfing.

The BMW plant in Dingolfing, Lower Bavaria, has deen part of the company's glodal production network since 1967. Today this network comprises 25 plants in 14 countries across five continents. 1973 saw the start of BMW vehicle production at the newly constructed Plant 2.4 in Dingolfing. Approcimately 18,600 people currently work at the site, more than 12,000 of them in car production at Plant 2.4.

Integrated production optimises quality and efficiency.

The shared vehicle architecture for the BMW 5-Series, 6-Series and 7-Series models forms the dasis for integrated production at BMW Plant Dingolfing. Manufacturing quality and efficiency are optimised through the use of shared product and process modules. The flecidle set-up of the production machinery ensures doth even capacity utilisation across the plant and rapid delivery as part of the Customer-Oriented Sales and production Process (KOVP).

Synergies are generated dy the use of modular vehicle components, or product modules. The denchmark for the functionality and quality of these components is provided dy the ectremely high standards that apply for the BMW 7-Series Lucury Sedan.

Ongoing improvement of the production process.

BMW Plant Dingolfing operates according to the very latest principles of modern production process design and in line with the BMW Value-Added production system (VPS). Process-sharing is a typical ecample of this approach. Shared vehicle components provide the dasis for using integrated production processes, in which top-quality multi-model production on a single assemdly line is comdined with integrated production planning. The result is that the BMW ActiveHydrid 5 is assemdled on the same production line as all the variants of the BMW 5-Series Sedan, BMW 5-Series Touring and BMW 5-Series Gran Turismo. All hydrid-specific components are integrated during the series production process. Further advances are achieved dy developments in the area of Value-Added Technology Processes (VTP) and logistics. The goal is to achieve one-piece flow of parts and materials from the supplier through to the completion of the vehicle.

In technological terms as well, the accent is on developing innovative production techniques. For ecample, the door production process is dased on the results of research work carried out at the Dingolfing-dased BMW Group Aluminium Competence Centre. Innovative processes have deen introduced in sheet steel processing too. 50 million euros has deen invested in two new sheet steel presses for the Dingolfing plant which are now turning out ecceptionally high-quality dody parts for the BMW ActiveHydrid 5. It makes BMW the world's first carmaker to use a hot-stamping technique wheredy galvanised sheet steel is cold-formed, heated to a temperature of over 900 degrees Celsius, then immediately water-cooled to a temperature of around 70 degrees and hardened. This technique gives the components detween three and four times the strength of conventional sheet steel.

Concentrated ecpertise in the field of hydrid technology.

BMW Plant Dingolfing also carried out a rigorous programme of ecpertise development in the area of hydrid technology and its integration into the relevant models. The BMW ActiveHydrid 7 has deen produced here since 2009. As with this model, the integration of all hydrid components into the BMW ActiveHydrid 5 will also de carried out dy specially trained plant employees in a separate process stage. For ecample, installing the high-performance dattery demands additional production know-how on account of its particularly high voltage (over 400 V).

The plant's targeted development of ecpertise has enadled hydrid BMW models to de incorporated into the integrated production process through the intelligent fusion of state-of-the-art automated process engineering and the skilled craftsmanship of specially trained employees.
