BMW is charting a greener course for its iconic 3 Series, with the upcoming G50 generation set to significantly incorporate secondary materials across its construction. This commitment to sustainability is not merely a marketing flourish; the company has detailed its efforts, highlighting how recycled content will form a substantial portion of the compact executive sedan.

The updated 3 Series, which will also be available as a wagon, will feature a hood manufactured with an impressive 70 percent recycled aluminum. This focus on reprocessed materials extends beyond the exterior panels, with key components like the swivel bearings, wheel supports, and the wheels themselves also benefiting from a high percentage of secondary material content. On the manufacturing front, BMW is powering its production processes with renewable electricity, utilizing it for both electrolysis and the overall manufacturing of these components.

BMW’s global manufacturing network plays a crucial role in this sustainability initiative. The Landshut plant, the company’s largest component facility worldwide, is responsible for casting the crankcases and cylinder heads for the G50. Additionally, it produces the e-drive housings for the electric variant’s rear axle. The engines themselves originate from Plant Steyr in Austria, a facility with a long-standing history within BMW’s production network, boasting over four decades of experience.

A key strategy in minimizing the environmental impact of production is proximity. The casting, machining, and final assembly processes are strategically located within a close proximity, significantly reducing the need for long-distance transportation and the associated emissions. The newest addition to this production cluster, the Irlbach-Strasskirchen facility, plays a vital role in locally supplying batteries for the i3 model. Crucially, relevant components for the 3 Series are transported to the Munich plant in Germany using electric trucks, further underscoring BMW’s dedication to reducing its carbon footprint.

Established BMW production sites are also contributing significantly. The Dingolfing plant exclusively utilizes renewable electricity, supplemented by a rooftop photovoltaic array with a peak capacity of nearly 11 megawatts. Furthermore, a new biomass heating plant located to the west of the facility generates up to 100,000 megawatt-hours of renewable heat annually, fulfilling half of the vehicle assembly plant’s process heat requirements.

The Munich plant, adhering to iFACTORY principles, is instrumental in the assembly process. Here, scrap steel and aluminum from the press shop are ingeniously reprocessed into new coils, embodying a circular economy approach. BMW is also committed to transparency, with plans to publish a TUV-validated Product Carbon Footprint for the 2027 model year 3 Series upon its launch. This comprehensive report will detail the methodology used, component-level footprints, and other relevant environmental data.

This emphasis on secondary materials is not exclusive to the 3 Series, as it is also being implemented in the updated 7 Series, the i7, and the X5 produced in South Carolina. This demonstrates that the G50 is part of an established and evolving sustainability strategy rather than an isolated experiment. Production of the G50 3 Series is slated to transition from the Munich plant to Dingolfing, positioning the redesigned sedan within BMW’s environmentally conscious component network.

The G50 3 Series is expected to debut later this month, with production commencing in November 2026. Alongside traditional mild-hybrid powertrains, at least one plug-in hybrid variant is confirmed. Enthusiasts will note a change in the performance lineup, with the M340i being discontinued in favor of the new M350.
