BMW is leaning on artificial intelligence and a dedicated battery quality-control chain at its Shenyang production base in northeast China to underpin the forthcoming new-generation iX3 electric SUV, according to PCauto. The plant has deployed AI-based visual inspection across stamping, body, painting and final assembly, aiming to catch surface defects and dimensional deviations in real time.
AI inspection and iFACTORY vision
In the stamping shop, a system developed by the tooling maintenance team uses AI visual recognition and digital-twin technology to scan each stamped part in milliseconds. The multi-threaded real-time detection replaces manual spot checks with an automated closed-loop verdict, and the data feeds into a digital-twin platform that traces defects to their source. Similar AI inspection is now used for weld quality, adhesive application, assembly precision and anti-corrosion coating thickness across all production lines.
The stamping shop's tooling maintenance team recently received the "National Worker Pioneer" award, one of the highest collective honours granted by China's trade union federation, PCauto noted. BMW's iFACTORY concept is also being implemented at Shenyang, with AI-based predictive maintenance monitoring equipment status and smart logistics robots working alongside automated guided vehicles to improve consistency.
Sixth-generation battery quality loop
For the new iX3, BMW has set up a separate quality-control chain for its sixth-generation battery, which uses China's first mass-produced large cylindrical cells with a 9-series high-nickel chemistry. The pack adopts a cell-to-pack design without modules to boost space utilisation, and module integration under the 800-volt architecture undergoes strict production validation and performance testing.
Thermal runaway protection follows a multi-layer approach, from insulating materials between cells to the rigid pack housing and real-time monitoring by the battery management system at vehicle level. Every pack must pass BMW's globally unified functional and safety verification before leaving the factory, with data synced to the digital-twin platform for full-lifecycle traceability.
PCauto reported that the domestic new-generation iX3 achieved a range of more than 800 kilometres in real-world testing around Qinghai Lake, and set a BMW record of 1,030.2 kilometres without recharging in internal extreme testing. The outlet said the battery quality loop is designed to reassure buyers that labelled range figures are not overstated, with capacity retention and safety verified before delivery.
BMW also said the new iX3 earned a five-star rating in the 2026 Euro NCAP tests during development, covering crash protection, active avoidance, human-machine interaction and accident rescue. The company has conducted vehicle calibration across China's plateau, high-temperature, rain and snow conditions, and extended its traceability system to suppliers such as Fuyao and Forvia Hella, applying the same quality standards to components like the windscreen's nano-coating reflectivity and the heating wires in the digital angel-eye light units.
