BMW Starts Gen 6 Battery Production in China

BMW Begins Mass Production of Sixth-Generation Batteries in China

BMW announced that its sixth-generation (Gen 6) high-voltage batteries had entered mass production in Shenyang, Liaoning province, while also revealing a road-test result for its long-wheelbase Neue Klasse i3 50L electric sedan. The vehicle traveled 1,213 kilometers without recharging, completing the test with 1% battery charge remaining. BMW reported that the drive covered expressways, national highways, rural roads, and urban streets. The company described the result as the longest distance one of its battery-electric vehicles had traveled on a single charge. The figure reflects a specific road test, however, and is not a certified range measured under a standardized testing cycle.

Neue Klasse i3 50L Completes a 1,213-Kilometer Road Test

The vehicle used for the endurance test was the Neue Klasse BMW i3 50L, a long-wheelbase electric sedan developed specifically for the Chinese market. According to BMW, the car completed the 1,213-kilometer journey across several types of roads and reached its destination with 1% charge remaining. The test vehicle carried a 113.4-kWh battery and recorded combined energy consumption of 8.8 kWh per 100 kilometers. These figures describe the configuration and conditions reported for this particular test; they should not be treated as a universal real-world range guarantee. BMW presented the result as a company record for distance traveled by one of its battery-electric vehicles on a single charge.

Shenyang Battery Project Represents a 10-Billion-Yuan Investment

BMW's Gen 6 battery project in Shenyang involves an investment of 10 billion yuan, equivalent to approximately $1.49 billion, and has a planned floor area of 240,000 square meters. BMW said the project is about five times the size of its existing battery production facilities. Construction began in May 2023, establishing the manufacturing base for the company's sixth-generation high-voltage battery program in China. The investment forms part of BMW's wider effort to support the rollout of its Neue Klasse electric vehicle platform through local production and technology partnerships. The announcement confirms that battery manufacturing has reached mass production at the Shenyang site, although it does not specify total battery output capacity.

Gen 6 Batteries Combine Cylindrical Cells and 800-Volt Technology

The Shenyang project brings together large cylindrical battery cells, battery-system integration, an 800-volt architecture, and sixth-generation electric drive technology. These elements are intended to support BMW's Neue Klasse models, linking battery production with the broader electric-drive system rather than treating the battery as an isolated component. Shenyang is the third location in BMW's global Gen 6 battery network, following Debrecen in Hungary and Ilbach-Straßkirchen in Germany. The company said the batteries manufactured in China will initially power the Neue Klasse iX3 and i3. With battery production underway, BMW stated that all three core components of its sixth-generation electric-drive system will be manufactured in China.

Energy Master System Adds Localized Battery Control Production

BMW had already begun trial production of its Energy Master system at the Shenyang powertrain plant in late September. The system functions as the central control unit for Gen 6 batteries, and BMW developed both its hardware and software in-house. The company described Shenyang as its only production base outside Germany capable of manufacturing the Energy Master system. It also identified the site as its only location worldwide that combines casting, engine production, high-voltage battery manufacturing, and Energy Master production at one facility. Together, these capabilities give the Shenyang complex a broader manufacturing role in BMW's electric-drive operations, extending beyond battery assembly alone.

China Production Supports Upcoming Neue Klasse Deliveries

Mass production of Gen 6 batteries establishes a manufacturing foundation for upcoming Neue Klasse deliveries in China. BMW opened pre-orders for the China-exclusive long-wheelbase Neue Klasse iX3 on August 21, with deliveries scheduled to begin in November. The source announcement does not specify the calendar year for those dates, so the timeline should be understood as reported rather than assigned an additional year. The newly tested Neue Klasse i3 50L is another China-focused model, with regulatory filings listing a wheelbase of 3,005 millimeters. That measurement is 39 millimeters longer than the wheelbase of the previous-generation i3 built in China, highlighting the model's market-specific long-wheelbase configuration.

BMW Develops China-Specific Software and Driver Assistance

Alongside local battery and vehicle production, BMW is adapting its Neue Klasse vehicles through software partnerships in China. The Neue Klasse i3's driver-assistance system was jointly developed with Momenta, identified in the source as listed on the Hong Kong Stock Exchange under code 6880. The car's infotainment system also incorporates artificial-intelligence voice features developed in collaboration with Alibaba and DeepSeek. These collaborations complement the company's localized manufacturing approach by involving Chinese technology partners in vehicle software and user-facing systems. The announcement does not provide detailed specifications for the driver-assistance functions or voice features, so their precise capabilities cannot be established from the reported information.

Key Specifications and Production Milestones

The announced developments cover the i3 50L road-test result, the Shenyang battery investment, and the production systems supporting BMW's Neue Klasse rollout. The figures below distinguish the reported test measurements from the project's manufacturing details and planned delivery timing. The 1,213-kilometer distance is a result from a specific road test, not a standardized certification figure, while the investment and facility area describe the Shenyang project. BMW has also identified the first vehicle programs for the locally produced batteries and outlined the role of the Energy Master system in battery control. The source does not state production capacity, independently certified range, or a full set of vehicle pricing and performance specifications.

Industry Impact & Outlook

BMW's Shenyang milestone connects next-generation battery manufacturing with vehicle assembly, electric-drive components, and locally developed software for the Chinese market. Producing all three core components of its sixth-generation electric-drive system in China could help the company coordinate manufacturing for its upcoming Neue Klasse models, while its partnerships address software features tailored to local customers. The 1,213-kilometer test may attract attention to the i3 50L's energy use and long-distance capability, but a single road test does not establish standardized range performance across different driving conditions. The next meaningful milestones identified in the announcement are the planned Neue Klasse iX3 deliveries and the continued rollout of Gen 6-equipped vehicles; production capacity and independently certified range figures remain unspecified.

Frequently Asked Questions

What did BMW announce about its Gen 6 batteries?
BMW announced that its sixth-generation high-voltage batteries had entered mass production at its Shenyang facility in Liaoning province, China. The project involves an investment of 10 billion yuan, approximately $1.49 billion, and a planned floor area of 240,000 square meters. The batteries combine large cylindrical cells with battery-system integration, an 800-volt architecture, and sixth-generation electric-drive technology. BMW said the batteries will initially power the Neue Klasse iX3 and i3, supporting the company's next phase of electric vehicle production in China.

How far did the Neue Klasse BMW i3 50L travel on one charge?
The long-wheelbase Neue Klasse BMW i3 50L traveled 1,213 kilometers without recharging during a road test reported by BMW.
