After natural fiber composite materials have proven their value on the route, you will finally find yourself on the way to the production cars of the BMW Group. Years of F&E and the tests have paid off – these renewable materials have now reached so -called “series production”, for which industry speaks: they are ready for the real world, not just racetracks.
This composite materials developed in collaboration with Swiss Clean-Tech company BCOMP, which tick all boxes on a flax basis, including the hard homologation standards for structural parts such as roofs. BMW has been working with BCCOR for years and has even invested in the company through BMW i ventures, which tells them how seriously they take this whole sustainability.




Light construction has always been a BMW specialty, and this new material not only cuts weight, but also CO₂ emissions. The exchange of conventional carbon fiber in the roof of the next generation model can report to around 40%, reportedly, the production -related CO₂. Before you even go into how much easier this stuff is to recycle or dispose of it.
The first test requirement for this technology? Of course motorsports. BMW M started its Formula program in 2019, and the M4 DTM and M4 GT4 have been in the following information since then. Bomp has even been an official partner of BMW M Motorsport since 2022.
Next comes the real proof: the 24 hours of nürburgring, where these materials are enforced on the BMW M4 GT4. As BMW M boss Franciscus van Meel puts it, “natural fiber composite materials are an essential element of innovative light solutions in motorsport”. Translation: You are fast, green and shortly before the mainstream.
And yes – turn the slogan from BMW M – what was born on the track, shortly before that to take to the street.
