BMW is proud to announce the BMW iX xDrive50. Conceived from the outset as purely electric mobility, the iX sees BMW redefining its successful Sports Activity Vehicle (SAV) concept. The BMW iX has been created to provide something beyond just mobility – an exhilarating driving experience combined with a sense of well-being for both drivers and passengers all the while enjoying the journey with safety, security and in luxury. Some of the advanced technology features making their BMW debut in the 516 hp iX include DC fast charging at up to 195 kW, available 5G and Personal eSIM support, a single-piece panoramic glass roof with electrochromic shading, the BMW Curved Display and iDrive 8, BMW Digital Key Plus with ultra-wideband radio technology, available Bowers and Wilkins Diamond Surround Sound with 4D audio and the iconic BMW kidney grille serving as an intelligent sensor panel with self-healing capabilities.
The iX xDrive50 brings together the company’s latest developments in the fields of design, sustainability, connectivity, electrification and digital services. The expertise accumulated by the BMW Group over many years in the area of sustainability has been channeled into the manufacturing of the BMW iX xDrive50. The most exacting environmental requirements have been put in place throughout the value chain and for the full life cycle of the car. Key components include closely monitored raw materials extraction, the exclusive use of electricity from renewable sources in the production process and an extraordinarily high proportion of recycled materials. A more powerful iX M60 model, with over 600 hp and the first all-electric Sports Activity Vehicle from BMW M GmbH, is planned for the future.
The BMW iX body structure’s aluminum spaceframe construction features an intelligent material mix that increases rigidity and minimizes weight. This also has a beneficial effect on passive safety, driving dynamics and electric power consumption. The mix of materials for the bodyshell includes CFRP and high-performance thermoplastics, along with high-strength steels and aluminum. Light, yet extremely torsion resistant CFRP components for the side frame, rain channels, roof frame, cowl panel and rear window frame together form a ‘Carbon Cage’ in the BMW iX body. The BMW Group has employed its many years of experience in working with this high-tech lightweight material – amassed during production of the BMW i models and the current BMW 7 Series – to use CFRP intelligently to reinforce the body while saving weight. The Carbon Cage has evolved from the Carbon Core used in the 7 Series and allows the best qualities of this high-tech material to also be appreciated visually.
The 5th generation of BMW eDrive technology is built around a drive unit which brings together the electric motor, power electronics and transmission as a highly integrated package within a single housing. This design approach enables a power density around 30 per cent greater than earlier electric drive systems could offer. The drive power produced by the motors is channelled via a single-speed transmission – installed in the same housing – to the front and rear wheels along the shortest possible path. The centrally controlled electric all-wheel drive links up with the chassis control systems to enable extremely rapid and precise metering of drive power according to the driving situation, the road conditions and the driver’s wishes. The latest electric motors developed in-house by the BMW Group have an efficiency factor of 93 percent, compared to less than 40 percent efficiency found in current combustion engines. The excitation of the rotor in the BMW iX motors is not induced by fixed permanent magnets, but the feed-in of electric energy.
A high-voltage battery with state-of-the-art battery cell technology is a key component of BMW’s 5th generation eDrive. The gravimetric energy density of the lithium-ion battery has been increased by around 20 percent over the previous-generation batteries. And the latest generation of the high-voltage battery displays excellent characteristics in charging and discharging, durability and safety. The iX’s high-voltage batteries are mounted low in the vehicle floor in an aluminum housing which acts as an integral component of the body. The latest advances made in the field of battery technology are the result of many years of relentless research and development work. The BMW Group has been producing modules and batteries for vehicles with electrified drive systems since 2013. The company can call on immense reserves of expertise and experience when it comes to both battery cell technology and the manufacture of model-specific high-voltage batteries.
