BMW Reaches Series Production Milestone with Natural Fiber Composites

BBG News

Summary

  • BMW to use flax-based composites in future production models
  • Debuted in BMW M4 GT4 during Nürburgring 24-hour race

BMW has now reached the point where it can mass-produce materials made from natural fibers, which is a significant leap forward in moving towards more eco-friendly manufacturing methods for its upcoming vehicle models. This technology was developed alongside the Swiss clean-tech company Bcomp and has already demonstrated durability and performance in racing environments like Formula E and the BMW M4 GT4. The use of these natural fiber composites by BMW signifies a dedication to lowering CO2 emissions, with preliminary tests indicating reductions as high as 40% compared to standard carbon fiber components.

The use of natural fibers in structural components such as roof panels has been verified, meeting tough safety standards. Instead of using carbon fiber-reinforced plastic (CFRP), BMW is switching to eco-friendly flax-based composites. This change not only makes production more environmentally friendly but also takes into account the sustainability of parts at their end of life. This innovation is a result of years of research and testing in motorsports, where lightweight materials must withstand extreme performance demands.

The new material is planned to debut in future BMW M vehicles and will be subjected to rigorous testing at the challenging 24-hour Nürburgring race, reflecting BMW M’s credo: “Race-bred. Street-tamed.
