BMW is set to integrate natural fibre composites into its production models, marking a significant step in its sustainability efforts. The company has invested years in research and development to create these innovative composites, made from organic matter. These materials have demonstrated their ability to meet the rigorous standards required for roof structures, as proven in homologation tests.
The flax-based lightweight composites were developed in partnership with Bcomp, a Swiss cleantech company. This collaboration is a key part of BMW’s strategy to lower CO2e emissions in the future. BMW i-ventures, the company’s venture capital arm, holds an investment in Bcomp.
The transition to natural fibres is crucial for reducing CO2 emissions and lowering the carbon footprint. These composites have been proven suitable for a range of applications, from interior to exterior components. Reports suggest a potential 40% reduction in overall emissions by replacing traditional carbon fibre parts with these new materials across the BMW lineup.
The technology has already proven its mettle, appearing in BMW M Motorsport’s Formula E program in 2019. Following this, the parts have also been used in the BMW M4 DTM and M4 GT4 models. BMW has been an official partner for BMW M Motorsport since 2022, specifically for the BMW M4 GT4.
Further testing will occur during the BMW GT4 24-hour race at the Nürburgring, ensuring the parts can withstand the demands of impact and mechanical stress. These components from BMW M Motorsport and Bcomp are slated to be implemented in upcoming BMW M series vehicles.
