In a move towards enhanced sustainability, BMW is integrating natural fibre composites into its upcoming production models. After extensive research and development, the BMW Group has created these composites from organic materials. These materials have successfully passed stringent homologation tests, proving their suitability for roof structures.
The lightweight composites, which are flax-based, were developed in collaboration with Bcomp, a Swiss cleantech firm. This partnership aims to reduce future CO2e emissions. BMW holds a stake in Bcomp through its venture capital arm, BMW i-ventures.
The shift to natural fibres is driven by the need to lower CO2 emissions and reduce the carbon footprint. Tests have shown these composites are ideal for both interior and exterior components. Replacing conventional carbon fibre parts with these new materials could cut emissions by up to 40% across BMW’s future models.
These parts have already been utilized by BMW M Motorsport in the 2019 Formula E season. Similar components have also been used in the BMW M4 DTM and M4 GT4, replacing traditional carbon fibre elements. Since 2022, BMW has become an official partner for BMW M Motorsport in the BMW M4 GT4.
These parts will be tested for durability at the 24-hour race on the Nürburgring. They will be used in future BMW M series vehicles as well.
