There was a time when carmakers tried very hard to prevent their prototypes from being seen and photographed. Back then, it was mainly professionals who hunted for the prototypes undergoing testing in remote places like the Arctic Circle, Death Valley (in America) and Africa. People like the Hans Lehmann, Brenda Priddy and the late Bob Dunne made a lot of money selling their pictures to magazines.
But with the advent of cameraphones and the possibility of anyone standing by the roadside taking a picture and then putting it on the internet where the whole world would see it, the thinking changed. And rather than let those people make money, the companies decided to exploit the attention by teasing the public with their own ‘spy shots’ of camouflaged cars.
Starting its third model generation since being introduced in 2009, the BMW X1 range includes a battery electric (BEV) variant for the first time – the iX1. Other electrified models of the range have plug-in hybrid powertrains and there are also petrol and diesel engine choices.
The new iX1 xDrive30 is the BMW Group’s first premium compact model based on a flexible vehicle architecture to feature an all-electric drive system. It has one electric motor at the front axle and another at the rear to power all four wheels and deliver xDrive performance. Total system output is 313 ps with up to 494 Nm of torque.
Interaction between the two motors is enhanced by a unique drive torque control which is interlinked with the DSC and the AWD-specific version of the near-actuator wheel slip limitation function.
5th generation BME eDrive technology
The fifth-generation BMW eDrive technology uses a 64.7 kWh high-voltage battery pack positioned flat within the vehicle’s underbody. The battery’s high energy density and the drive system’s efficiency achieve combined power consumption of 18.4 – 17.3kWh per 100 kms and can cover a driving range claimed to be up to 438 kms.
Combined Charging Unit
The Combined Charging Unit in the iX1 enables single and 3-phase AC charging up to 11 kW, optionally increased to 22 kW. This allows the battery to be fully recharged from empty in 6.5 hours as standard, or 3 hours 45 minutes as an option. DC recharging at up to 130 kW is claimed to raise the energy level from 10% to 80% in 29 minutes, or increase range by 120 kms in 10 minutes.
An optimised cooling strategy for DC charging improves the durability of the battery. Alternating phases of full and partial cooling power are used to prevent cell temperatures dropping too low during fast charging, shortening charging times and reducing ageing.
BMW IconicSounds Electric
As with other BMW BEV models, there’s BMW IconicSounds Electric which treats drivers to soundscapes developed as part of a collaboration between the BMW Group and 2-time Academy Award-winning film score composer, Hans Zimmer. The character of the sound alters according to the vehicle setting. A drive sound emitted externally at low speeds helps to protect pedestrians by making them aware that the car is approaching.
Larger dimensions
The surface treatment, lines and exterior design details of the iX1 display its Sports Activity Vehicle (SAV) identity more clearly than before. Distinctive design features include the stretched silhouette, almost square wheel arch contours and the signature BMW X model styling of the front and rear ends. When viewed from the rear, the slim tailgate window, horizontal lines, striking LED lights and flared wheel arches produce the typical SAV look.
At the centre of the new front end design stands the large, almost square BMW kidney grille, its contouring highlighted by the three-dimensional chrome surround. The grille bars are finished in Black high-gloss as standard. In the outer areas of the lower air intake, large chrome strips accentuate the classy design of the front end.
The X1 bodyshell is larger than its predecessor – by 53 mm in length to 4500mm, 24 mm in width to 1845 mm and 44 mm in height to 1642mm. The wheelbase of 2692 mm is 22 mm longer than before, while track widths have increased by 31 mm at the front and rear.
More space, optimised comfort
With the enlarged body, there are more generous amounts of space. Key features include the slender instrument panel, a stage for the BMW Curved Display, and a ‘floating’ armrest with integral controls. The raised seating position also provides the commanding view which is one of the reasons why many people like SAVs. The newly developed seats offer optimised comfort over long distances and extended functionality, with their prominent bolsters and adjustability of seat angle and depth.
The BMW Curved Display is framed by solid-looking trim pieces which extend out to the doors. Four interior trim variants, including the new open-pore fine eucalyptus wood and Aluminium Hexacube for the M Sport model, allow owners to individualise the design.
With a glass surface measuring around one square metre, the panoramic glass sunroof floods the interior of the iX1 with light and can also allow fresh air in. The roller blind cover for the glass roof now has a multi-layer design and is also electrically operated.
The fore-and-aft adjustment of the rear seat bench and triple-split backrest provides variability in the cabin configuration. The rear seat can be moved forward up to 13 cm, allowing boot capacity to expand from 540 litres to 1,600 litres.
Although the Malaysian government has not provided a ‘roadmap’ or formulated a policy that is appealing enough to investors, BMW Group Malaysia has gone ahead with its own electrification program, albeit in a limited manner. To date, it has introduced a fully electric BMW model (the i3) and also the MINI Electric, as well as a number of models with hybrid powertrains.
Now, the company which brought us EfficientDynamics is pushing ahead with electric vehicles by offering a new-generation of fully electric models which are under the BMW i brand. The upcoming EV portfolio will consist of the iX xDrive40, the iX xDrive40 Sport, iX xDrive50 Sport, iX3 and i4 eDrive40.
BMW iX3
Milestone for BMW Group Malaysia
“The incoming fleet of electric vehicles from BMW i will present all the best possibilities of Sheer Electric Driving Pleasure to loyal BMW customers and EV enthusiasts alike in Malaysia, with no compromise. More importantly, it will also drive the All-New Sustainability Strategy for the BMW Group in Malaysia,” said Hans de Visser, MD of BMW Group Malaysia. “This is a milestone for the BMW Group, even more so for us at BMW Group Malaysia. We have been in the driver’s seat in accelerating innovation, awareness on new and sustainable technology for the automotive industry, shaping the infrastructure for premium electrified vehicles in Malaysia since 2015.”
The iX pioneers ‘Shy Tech’ which is a design principle used by BMW designers that has advanced technology integrated but out of sight, available when needed or explicitly desired. Additionally, the iX will also feature BMW IconicSounds Electric that adds the unmistakable sounds of BMW and BMW M models to the driving experience (bearing in mind that EVs run quietly).
BMW i4 eDrive40
BMW eDrive technology
The cars use BMW eDrive technology for the powertrains and are claimed to have up to 630 kms of range from a fully-charged battery pack. While that’s an impressive range, BMW Group Malaysia has also been working on expanding the recharging network around the country. It is rapidly expanding the BMW i dealer network to key cities across the country and DC Fast Chargers will also be installed at all BMW i dealers for public use to further accelerate the availability of charging infrastructures in Malaysia. Rapid-charging DC Chargers will be made available for quick on-the-go charging at selected dealerships nationwide.
The i4 is said to be epitome of the sustainable sports 4-door Gran Coupe, built with specific focus on electric driving dynamics from the outset. In keeping with its powertrain of the future, the i4 also has advanced styling. Its power output is equivalent to 340 ps which can propel the car from 0 to 100 km/h in a claimed 5.7 seconds, while covering up to 590 kms before the battery pack is empty. Of course, like an internal combustion engine, how fast the ‘fuel’ is used up is dependent on various factors while driving.
Pre-booking now open
Pre-booking for the new BMW i models can be made on the BMW Shop Online platform with a fee of RM5,000. Registration of interest for the iX xDrive50, iX3 and i4 eDrive40 are also open on the official BMW Malaysia website.

With the Balloon Financing Plan from BMW Group Financial Services Malaysia, the iX xDrive40 and iX xDrive40 Sport can be owned with a monthly instalment plan starting from RM4,888 and RM5,478, respectively (based on estimates of an 80% loan on a 5-year tenure).
“We look forward to reigniting local interest and uptake for electromobility, in foresight of the much-discussed upcoming Low Carbon Mobility Blueprint. We have partnered with GreenTech Malaysia from the very beginning to grow the local charging infrastructure network as part of our key strategies to shift Malaysia towards a low carbon mobility future. Moving forward, we aim to give Malaysians the confidence to choose electric for their next – or even first – drive. In fact, there are more plans set to activate in the upcoming months that will encourage a positive reception of this future-focused way of mobility, of which we hope will also be strengthened by the upcoming revision of government policies towards electromobility,” Mr. de Visser added.
With a year still to go before its market launch at the end of 2021, the BMW Group is providing a first look ahead to the future BMW iX, the production reality of the BMW Vision iNEXT. Currently undergoing extensive development work, the iX is the first model based on a new, modular, scalable future toolkit developed by the Group.
Conceived from the outset for purely electric mobility, the iX sees BMW redefining the Sports Activity Vehicle (SAV) concept that it introduced in the late 1990s with the X5. Just as the X5 was a pioneering model for the carmaker, so too is the iX which is the first representative of what the company promises to be ‘a trailblazing generation of cars’.
The iX harnesses the latest innovations in the fields of electrification, automated driving and connectivity to deliver a mobility experience with people at its core. To this end, its design has been developed from the inside out to provide quality of life and wellbeing for drivers and passengers.
BMW Group’s new technology flagship
The design and technology of the iX form an overall package that lays the foundations for what is in many respects a new kind of driving experience. In so doing, it comprehensively embodies the character of the BMW i brand, whose mission is to transform personal mobility. BMW i plays a central role at the BMW Group as a ‘workshop for the future’ and driver of innovation across the company.
Testing the BMW eDrive systemThe iX will go into production at BMW Plant Dingolfing from the second half of 2021 as the BMW Group’s new technology flagship. It brings together the company’s latest developments in the strategic innovation fields of Design, Automated Driving, Connectivity, Electrification and Services. Added to which, the vehicle concept and design of the iX are rooted in an all-embracing approach to sustainability. This is reflected in areas of the car such as its optimised aerodynamics, intelligent lightweight design and extensive use of natural and recycled materials
Fifth-generation BMW eDrive technology
The iX will adopt the BMW eDrive technology and the fact that this technology is in the fifth generation shows how far the BMW Group has come in the field. The eDrive comprises two electric motors, the power electronics, the charging technology and the high-voltage battery – and guarantees exceptional operating and running efficiency.
The power unit developed by the BMW Group has been manufactured sustainably without the use of critical raw materials known as rare earths and will, by the most recent calculations, develop maximum output of more than 370 kW – equivalent to 500 hp. That will power the iX from 0 to 100 km/h in less than 5.0 seconds, it is claimed.
At the same time, the vehicle’s clear aim is to post an exceptionally low combined electric power consumption figure for its segment of less than 21 kWh per 100 kilometres in the WLTP test cycle. A gross energy content of more than 100 kWh should enable the latest-generation high-voltage battery to record a range of over 600 kms in the WLTP cycle. That equates to more than 480 kms according to the US EPA’s FTP-75 test procedure.
10 minutes for over 120 kms range
The new charging technology of the iX enables DC fast charging at up to 200 kW. In this way, the battery can be charged from 10% – 80% of its full capacity in under 40 minutes. For those who are in a hurry and cannot spend too much time on recharging, 10 minutes of recharging will provide a range of over 120 kms (this of course depends on driving conditions). It is projected to take less than 11 hours to charge the high-voltage battery from 0 to 100% at 11 kW from a Wallbox.
The battery pack fitted in the iX is designed as part of a long-term resource cycle and enable an exceptionally high recycling rate. The power used to produce the battery cells for the battery pack as a whole come exclusively from renewable sources.
New technology toolkit
The new technology toolkit making its debut in the iX also provides the platform for significant progress in the areas of automated driving and digital services. For example, the level of computing power has been developed to process 20 times the data volume of previous models. As a result, around double the amount of data from vehicle sensors can be processed than was previously possible.
“We are setting new industry standards with the technology in the BMW iX. The iX has more computing power for data processing and more powerful sensor technology than the newest vehicles in our current line-up. 5G-capable, it will be given new and improved automated driving and parking functions and uses the high-performing fifth generation of our electric drive system,” said Frank Weber, Member of the Board of Management of BMW AG, Development.
Familiar but fresh design
50 years ago, when cars of the future were displayed at motorshows, they either looked way too extreme or were small bubbles on wheels. However, the iX, while having a pioneering character, has familiarity in its design. It is not extreme, but the exterior represents a distinctive re-imagining of the proportions of a large BMW SAV.
The iX is comparable with the X5 in length and width, and is almost the same height as the X6 on account of its flowing roofline. The size of its wheels would bring to mind the larger X7. The minimalist use of character lines and generously shaped surfaces conjure an aura of supreme assurance. The crisp lines, clear structure and almost rectangular contours around the wheelarches contribute to an imposing body design with optimised aerodynamics.
At the centre of the front end stands the prominent, vertically emphasised kidney grille. Since the electric drive system requires only a small amount of cooling air, the kidney grille is completely blanked off. Its role has duly turned digital and here it functions as an ‘intelligence panel’. Camera technology, radar functions and other sensors are integrated into the grille behind a transparent surface.
Developed and produced at the BMW Group’s LuTZ lightweight design and technology centre, the kidney grille for the BMW iX presents a technologically lavish advertisement for intelligent mobility. The grille has reinvented itself as an innovative and multifunctional high-tech interface for the advanced driver assistance systems with which the iX paves the way for automated driving.
Discreetly integrated technology
The exterior design highlights also include the slimmest headlight units ever to feature on a volume-produced model from BMW; the flush-fitted door openers (operated at the press of a button); the frameless side windows; the tailgate (which has no separation joints and extends across the whole of the rear) and the likewise extremely slim rear lights.
The BMW kidney grille is not the only example of how the principle of ‘shy tech’ has been integrated into the design of the BMW iX: an array of other cameras and sensors are likewise positioned discreetly, the filler neck for the windscreen washer fluid is concealed under the BMW logo on the bonnet and the rear-view camera has been integrated into the BMW logo on the tailgate. The technology stays in the background and only becomes apparent as and when the relevant functions are called into action.
“The BMW iX shows how we can give new technologies a very modern and emotionally engaging design. The car is technologically highly complex, but it feels very clear and uncomplicated,” explained Adrian van Hooydonk, Senior Vice-President BMW Group Design. “The BMW iX offers a mobile living space in which people will feel at ease and the car’s intelligence is always available without becoming obtrusive.”
Interior design: people at centre stage
A high level of spaciousness, a mixture of high-quality materials, newly developed seats with integral head restraints and an exceptionally large panoramic glass roof immerse all 5 seats of the cabin in a luxurious, lounge-like ambience. The all-new architecture of the iX cabin underpins a perfectly clear and straightforward functionality that revolves entirely around the needs and emotions of the driver and their fellow occupants.
The drive concept means there is no centre tunnel, adding to the open, airy feel while also allowing extra legroom in the front and rear, sufficient space for storage facilities, and a centre console crafted to look like a high-quality piece of furniture.
The displays and controls are all stripped down to the essentials, further reinforcing the impression of an uncluttered cabin offering a place of relaxation. The technology used intelligently and only becomes visible when it is needed. This makes it intuitive to use rather than seeming overly complex.
The Head-Up Display’s projector is discreetly recessed into the instrument panel, so it is almost invisible. The hexagonally shaped steering wheel, a rocker switch for gear selection and the BMW Curved Display – which forms part of the next-generation BMW Operating System – clearly advertise the futuristic cockpit.
Intelligent lightweight design
The energy and range of the iX benefit from innovative solutions in the areas of lightweight design and aerodynamics. Its body structure, featuring an aluminium spaceframe and innovative Carbon Cage, can claim extremely high torsional stiffness, which in turn enhances agility and maximises occupant protection, while minimising weight. The intelligent material mix, with a variety of materials employed exactly where their specific properties can be utilised to best effect, is unique in this segment.
Together with the superior aerodynamics (0.25 Cd), the intelligent material mix helps to endow the iX with remarkably composed, relaxed driving characteristics combined with instant, precise response to every movement of the accelerator and turn of the steering wheel.
Six years after it appeared, the BMW i8 Coupe will be retired as its production cycle comes to an end. A success story as a unique symbiosis of futuristic design and pioneering technology, it was the BMW Group’s first plug-in hybrid model that spurred interest and excitement for electrified drive technology and laid the foundation for the BMW Group’s now broad range of plug-in hybrid models.
At the same time, the i8 developed into the world’s most successful sportscar with an electrified drive system. With more than 20 000 units sold since 2014, it achieved higher sales than all competitors in its segment combined. Its global market share has been more than 50% in the segment of sportscars with electrified drive for years and the i8 will be able to maintain this leading position until the middle of April 2020.
The i8 began as the BMW Vision EfficientDynamics, a concept car shown at Frankfurt Motorshow in 2009. The response was very enthusiastic, and BMW said that the central features of its design and technology would be transferred to a production model of the new BMW i brand.
The BMW Vision EfficientDynamics concept evolved into the i8 concept in 2011. It was used in one of the Mission: Impossible movies.
Launchpad for electrification strategy
The i8 had its world premiere at the same motorshow 4 years later, together with the i3. The double debut was the starting signal for implementing a comprehensive electrification strategy, with which the BMW Group set the early and consistent course for a model programme geared towards sustainable driving pleasure.
Today. Pure electric and plug-in hybrid models are available in all relevant segments, from the compact and midsize class, through the BMW X models, to sportscars and luxury sedans. The BMW Group plans to expand its range to include 25 electrified models by 2023, more than half of which will run on electric power alone.
Pioneer and flagship
As a pioneer and flagship for driving pleasure with plug-in hybrid technology, the i8 was an ideal car for the job right from the start. New paths were forged with the BMW i specific vehicle architecture and the plug-in hybrid system. The combination of a passenger cell made of carbonfibre reinforced plastic (CFRP) with an aluminium chassis was just as revolutionary as the intelligently controlled interaction of the combustion engine and electric motor.
The control of its plug-in hybrid system was designed both for dynamic power delivery and for the most efficient interaction of the two engines. The combustion engine with BMW TwinPower Turbo technology transfers its power to the rear wheels. The electric motor drives the front wheels. The result is a hybrid-specific all-wheel drive with a noticeably positive influence on traction, agility and driving stability.
This, and the spontaneous power delivery of the electric motor with a maximum torque of 250 Nm available immediately from standstill, means that the sporting character of the i8 also comes into its own in purely electric and therefore locally emission-free driving. Up to 120 km/h can be reached in pure electric driving mode and the combined drive torque of both powerplants unleashes performance characteristics similar to a high-performance sportscar.
Beyond eDrive technology
Right from the start, the pioneering function of the i8 extended far beyond establishing BMW eDrive technology in an iconic sportscar. The extensive use of CFRP in the body structure and the clearly visible measures to reduce air resistance set new standards in the areas of intelligent lightweight construction and aerodynamics. Together with the i3, the sportscar also paved the way for innovative manufacturing technologies, with which the BMW Group became a pioneer in the use of CFRP in the industrial production of volume-produced automobiles.
Already a milestone in the history of the BMW Group
The Leipzig plant is currently producing the 200 units of the limited Ultimate Sophisto Edition of the i8. One of the edition models was already manufactured in December 2019 as the 20,000th unit of the model. Among the milestones in the history of sportscars, its sales figures are well ahead of classics such as the M1, of which only 399 units were produced for road use, and also ahead of the Z8 roadster, which was built in some 5,000 copies.
The BMW Concept i4, one of the many models that were to be unveiled at the now-cancelled Geneva International Motor Show, provides a look ahead to the new i4 model to be launched in 2021. It will be the BMW Group’s first all-electric model in the premium midsize class.
“The BMW Concept i4 brings electrification to the core of the BMW brand,” said Adrian van Hooydonk, Senior Vice-President, BMW Group Design. “The design is dynamic, clean and elegant. In short: a perfect BMW that happens to be zero emission.”
“The design of the BMW Concept i4 shows fantastic proportions, a powerfully expressive character and, of course, a lot of attention to detail,” added Domagoj Dukec, Head of BMW Design. “With the Curved Display, we have redefined BMW’s signature driver focus in an extremely elegant way. At the same time, the BMW Concept i4 transports a feeling of sustainable driving pleasure.”
As part of the package, the Concept i4 includes several exterior and interior design elements which will be incorporated in both the i4 and other electrically-powered production vehicles.
Electrifying aesthetics
The long wheelbase, fastback roofline and short overhangs form a basic profile for a Gran Coupe. With its four doors, the Concept i4 offers not only a high level of everyday usability and practicality, but also a much larger interior than the car’s modern and dynamic proportions would immediately suggest.
Crisp, smooth lines and taut volumes merge into a rich, smoothly contoured sculpture and create a clear surfacing language. The modern exterior paint shade known as ‘Frozen Light Copper’ mirrors that on the BMW Vision iNEXT and showcases the interplay of surfaces to visually stunning effect.
Blue elements in the front end, flanks and rear end point to the car’s BMW i origins. They shine a spotlight on the signature BMW i icons and bring the technology below the surface to the fore – for example, the kidneys in their role as an intelligence panel, the mouldings in the side skirts concealing the battery technology, and the diffuser elements in the rear end, which fill the design space vacated by exhaust tailpipes and enhance aerodynamic efficiency.
A host of aerodynamic measures help maximise the car’s electric range. The blanked-off kidney grille and clear aero lips provide detail examples of sophisticated airflow engineering at work.
Another distinctive area of the car are the wheel rims. These have been designed exclusively for the Concept i4 and blend aerodynamic and lightweight design; smooth – and therefore aerodynamically optimised – surfaces contrast with ultra-low-weight, high-strength spokes.
The front-end treatment presents the familiar BMW icons in a new look, lending a visually powerful face to the electric age at BMW. The prominent, closed-off kidney grille provides a tangible connection between the past and future of BMW.
The BMW icon also gains new functionality: With no combustion engine to require cooling, the grille now serves primarily as an ‘intelligence panel’ housing various sensors. The headlights likewise provide a bridge between the past and the future; the classical 4-eyed front end has a very modern and pared-back interpretation.
Innovation meets minimalism
The interior of the Concept i4 focuses on those times when the driver chooses to pilot the car themselves. To this end, every element in the front of the cabin is trained on the driver. The new Curved Display teams up with the steering wheel to reveal a new take on driver orientation and offers a look ahead to the display in the production versions of the iNEXT and i4.
The Curved Display encompasses a large proportion of the section in front of the driver and almost all operating functions are integrated into the display. This is part of an overall approach centred on reducing the number of haptic controls to the minimum.
Spacious rear compartment
Rear-seat passengers are greeted by a generously-sized compartment offering levels of headroom and legroom that exceed expectations of a coupe. The cut-out in the head restraints is a classy detail that references sporty BMW models from the current line-up.
The rear seats extend the horizontal graphic emerging from the doors to create a lounge feel in the rear. Meanwhile, the outer seats reprise the dynamic form of the front seats, heightening the sporting flavour. They also use very little stitching, which further emphasises the clean and modern feel.
The sound of the Concept i4
The Concept i4 is not only characterised by its individual design but also by its own visionary and unique sound. It was developed under the brand name of BMW IconicSounds Electric by world renowned composer Hans Zimmer together with BMW Sound Designer Renzo Vitale.
BMW IconicSounds Electric aims to emotionalise BMW’s electric vehicles and make them audible using individual sound worlds. The sound combines BMW’s past and future, ranging from the driving sounds in ‘Core’ mode to the more intense and pronounced sounds of ‘Sport’ mode. Also included are the sounds of the door opening and the starting scenario.
Fifth-generation BMW eDrive technology
The electric motor, power electronics, charging unit and high-voltage battery use fifth-generation BMW eDrive technology. These are all-new developments enabling the BMW Group to take another significant step forward in the field of electrified drive systems. The electric motor developed for the i4 generates maximum output of up to 390 kW (530 ps), which ranks it alongside a current BMW V8 combustion engine.
Electrical energy is drawn from a newly designed high-voltage battery pack with the very latest battery cell technology. The version of the battery developed for the i4 has extremely slim construction and optimised energy density. It weighs roughly 550 kgs, has an energy content of around 80 kWh and can provide an operating range that is claimed to be up to 600 kms.
A new BMW brand identity
BMW is unveiling the brand’s new look for the first time. The new logo for communications also provides the basis for the badge on the Concept i4. Its two-dimensional and transparent design ensures seamless integration and brings the special exterior colour shade to even greater prominence.
On its way to being ready for production, the BMW iNEXT is completing additional vehicle testing under particularly demanding conditions. Intensive test runs in the freezing cold at the polar circle are now being followed by a contrasting program in the Kalahari in southern Africa.
In addition to extreme heat and solar radiation, permanent dust formation and off-road terrain with its sand, pebble and gravel tracks pose exceptional challenges for the BMW Group’s technology flagship.
The test drives through the desert and savanna regions in the northwest corner of South Africa are in temperatures that would drain any mobilephone battery in no time at all. This puts a severe test on the integrated cooling concept for the high-voltage battery, the electric motor and the vehicle electronics.
During extensive heat tests, the car is repeatedly exposed to the heat of the sun for hours and later cooled down. In this way, the developers test not only the operability of the electrical systems but also the temperature stability of the materials used in the interior.
Moreover, the interior air conditioning, which operates by means of thermal pump technology, its control system and all further components of the electronics, are subjected to the extreme conditions of the desert climate.
Every part and system stress-tested
In this literally hot phase of the product development process, not only do the drive and suspension components of the iNEXT – a car designed for all-electric mobility – have to provide proof of their functional safety, durability and reliability, but also the car’s bodywork, interior, driver assistance systems and digitalisation technology.
The ‘hot climate’ tests are an integral part of a both extensive and varied development and test program. Prototypes are subjected virtually in time-lapse to the stress of an entire car’s service life.
Real-world conditions
Like every new BMW model, the prototypes are also driven at the proving ground at Miramas in southern France, the Nurburgring Nordschleife and other racetracks as well as the Winter Centre in Sweden.
With high-speed operation, stop/go traffic, extreme temperatures below and above zero, testing on ice and snow as well as desert sand and gravel, the pre-production cars are put through a concentrated form all of the challenges an automobile may face in everyday traffic over a period of many years.
Fifth generation BMW eDrive technology
Featuring fifth-generation BMW eDrive technology, the iNEXT is said to set new benchmarks in sportiness, efficiency and range in a battery-powered automobile. The car’s suspension control and driver assistance systems pave the way for a further step towards autonomous driving. Current innovations in the field of operation and digitalisation also underscore the future-oriented character of the iNEXT.
Production of the iNEXT will commence at the BMW Dingolfing plant in 2021. Designed as a modern Sports Activity Vehicle, the new model combines the latest innovations defined by the BMW Group in its corporate NUMBER ONE > NEXT strategy for the future fields D-ACES (Design, Autonomous, Connected, Electrified und Services).
In 202, BMW’s first purely electric Sports Activity Vehicle (SAV) – the iX3 – introduces BMW eDrive technology of the fifth generation and, starting in 2021, the technology will also be available in the i4 and the iNEXT. Production of the iX3 will commence in 2020 for the world market by the joint-venture company, BMW Brilliance Automotive, in China.
The iX3 is a further milestone in the consistent realisation of the BMW Group’s electrification strategy. In 2020, the new SAV will become the brand’s first model available both with conventional petrol and diesel engines as well as plug-in hybrid and purely electric drive. With this ‘power of choice’ offer, the company is taking into account the various different requirements and needs of their customers worldwide as well as maximum effectiveness in the reduction of carbon dioxide emissions.
The core of BMW’s 5th generation eDrive technology.
The fifth-generation BMW eDrive technology is the result of consistent development work within the framework of BMW EfficientDynamics and the experience gained by the BMW Group in the field of electric mobility spanning more than 10 years. All powertrain components were developed solely by the BMW Group.
Moreover, the electric motor and the high-voltage batteries are produced in corporately owned manufacturing facilities. In this way, the BMW Group ensures it has a decisive influence on the product properties and the quality of each component. Furthermore, the drive unit and the high-voltage battery unit are flexibly scalable in terms of power and energy content and can thus be used in various different vehicle concepts and segments.
EfficientDynamics at its best
In the iX3, EfficientDynamics reaches a new level. The new technology comprises a drive unit in which electric motor, system electronics and transmission are brought together into a central housing. As a result, the required installation space of the drive technology and its weight are considerably reduced. The ratio between motor output and weight of the drive system improves around 30% compared to the previous generation.
The iX3 will be the first model with 5th generation eDrive technology, followed by the i4 and the iNEXT in 2021.
The electric motor installed in the iX3 delivers a maximum power output of 210 kW/286 hp. The torque of 400 Nm allows for high initial acceleration and keeps a high level even at the upper motor speeds because of exclusive BMW design measures. A further special feature of the electric motor being deployed in the iX3 for the first time is a construction method that eliminates the need for rare earth materials.
The electric motor transfers power to the rear wheels. This enables a further increase in drive system efficiency. Moreover, the range of the BMW iX3 benefits from the drive design conveying the traditional BMW rear-wheel drive experience.
BMW’s electrified models in 2019
Batteries with significant higher energy density
The high-voltage battery unit is based on the latest evolution in NMC-811 technology in BMW typical prismatic design. The BMW Group has outstanding development capabilities in this field. This know-how flows into precise specifications with regard to the use of materials and battery design, according to which the battery cells are produced. Consistent R&D work not only raises energy density but also constantly improves all battery cell characteristics, in particular also durability and safety.
Greater range because of high efficiency
With a net energy content of 74 kWh, the high-voltage battery pack achieves a range of more than 440 kms in the legislative WLTP test cycle. Within its segment, the iX3 boasts not only a unique low power consumption of less than 20 kWh/100 kms (accordingly to the WLTP test cycle) but also stands for a novel ratio between battery size and range.
Thanks to the favourable efficiency rating of the drive components and the high energy density of the high-voltage battery unit, the iX3 achieves a range that is only possible for common electric vehicles with larger and thus heavier batteries.
Although the model will only appear in showrooms in 2 years’ time, BMW is telling the world about the fourth model in its I sub-brand range – the i4. This will be the first purely electrically-powered model for the premium mid-range with the functionality of a 4-door Gran Coupe and emissions-free mobility.
More importantly, BMW promises to transfer the brand’s characteristic core features to the age of electric mobility, particularly the qualities of the 3-Series. Design-wise, it will be based on the i Vision Dynamics concept car (pictured below) shown in 2017 and sit on the CLAR platform.
The i Vision Dynamics concept
The development of the i4 is part of a comprehensive product offensive by the BMW Group in the field of models with electrified drive. The company currently has the biggest range of all-electric and plug-in hybrid models within the competitive field. By 2023, the BMW Group will have 25 models with electrified drive in its program.
Fifth-generation BMW eDrive technology
The drive technology of the i4 will set new standards in terms of power density, efficiency and range in locally emissions-free driving. The electric motor, power electronics, charging unit and high-voltage battery are entirely new. Together, they form the BMW eDrive technology of the fifth generation, with which the BMW Group has made further significant advancements in the field of electrified drive.
From 2020 onwards, the fifth- generation BMW eDrive technology will be introduced first in the iX3 and then in the iNEXT and i4. The electric motor developed for the i4 delivers a maximum output of around 390 kW/530 bhp, reaching the level of a V8 engine in current BMW models fitted with a combustion engine. 0 to 100 km/h acceleration is expected to be around 4 seconds, with a top speed of more than 200 km/h.
The fifth generation of BMW eDrive also includes a newly designed high-voltage battery featuring the latest battery cell technology. The design of the high-voltage battery developed for the i4 is characterised by its extremely flat design and optimised energy density. With a weight of some 550 kgs, it has an energy content of around 80 kWh. This gives a claimed range of approximately 600 kms.

Modular, flexible drive and battery storage technology
A flexible vehicle architecture, the flat, low-positioned high-voltage battery and the compact drive technology create a high degree of freedom in realising a model- specific design. The electric drive component, its charging unit and high-voltage battery are all developed and produced in-house by the BMW Group.
This drive system is compatible with all vehicle concepts and will be available for different models in a range of output levels. The highly integrated design of the system allows a significant increase in power density as well as a reduction in weight and manufacturing effort. Production of future-generation electric motors will no longer require materials categorised as rare earths.
The next generation charging unit is characterised by a uniform package suitable for all future vehicle architectures. It can be used in plug-in hybrid models as well as in purely electrically powered vehicles and is designed for a charging capacity of up to 150 kW. This allows the high-voltage battery pack to be charged to around 80% of its full energy content in around 35 minutes. This results in a charging time of around 6 minutes for a range of 100 kms.
