The first series-produced BMW i4 has today rolled off the production lines at BMW Group Plant Munich. The company’s home plant now manufactures all drive variants on a single assembly line. “For the plant and team, the launch of the BMW i4 is a milestone on the road to electric mobility,” said Milan Nedeljković, BMW AG Board Member for Production. “By 2023 more than half of all vehicles from our Munich facility will have an electrified drive. The majority will be fully electric. So Munich goes fully electric.”Setting up production of the fully electric BMW i4 in the confines of the almost 100-year-old plant, the conversion and installation of systems proved particularly challenging. “We succeeded in integrating the new vehicle into our existing systems without halting production. The team and our partners did an amazing job,” added Peter Weber, Director of BMW Group Plant Munich. Space constraints notwithstanding, existing systems were removed, and new ones installed and ramped up. “Our bodyshop is a shining example of intelligent, efficient integration. Most of the new production processes for the BMW i4 can be carried out on the existing bodyshop systems,” Weber explained.

Body shop robots are fitted with a combined total of over 600 welding tongs. If the tongs ever need replacing unexpectedly, it costs significant time and money. Moreover, many of the robots are difficult to access, so dismantling and replacing their tongs can take hours.Until now, the condition of tongs has been monitored by eye, by a member of the production team. But in recent months, the maintenance specialists at Plant Munich have been fitting sensors to all the tongs to measure friction levels three times per shift and report any abnormalities. The data they produce is constantly evaluated by software, allowing potential machine failures to be predicted. Martin Hilt, Innovation and Digitalisation Officer at Plant Munich, explains: “Because we have the sensors and collect their data in a cloud, we can now monitor round-the-clock whether any maintenance work is needed. So, we can plan any replacements better and potentially schedule them for a production break.”
Despite comprehensive cleansing systems, vehicle bodies can pick up dust particles as they make their way to the paint line. Though invisible to the human eye, the particles can affect the quality of the finish. Until now, potential defects have gone undiscovered after the painting process, revealed only by the automatic surface inspection. They then had to be reworked, or the bodies repainted completely.Now, however, every paint shop system incorporates sensors that measure dust levels and allow the quality of paintwork to be predicted. “We can now tell quickly if the environmental parameters are not quite right at some point, either within the paint shop or in one of the buffer areas. It takes a lot of data to do this, which we collect throughout the process, evaluate historically and analyse in real time,” explains Martin Hilt.Over the last few months, a further special sensor developed by Plant Munich has been measuring dust levels on body parts at the beginning of the painting process, before and after the emu feather rollers. In the future, when dust levels are too high, car bodies will pass through the paint shop untreated and be sent for further cleansing.
