In March 2025, the  was taking its first steps to qualify and apply sustainable carbon fiber composites into its W16 race car. At the end of September 2025, the Azerbaijan Grand Prix saw the debut of this bio-based carbon fiber composite material — rear brake duct wheel shields which were developed using a novel resin that includes 30% bio-based materials.

This marked the the first time the team used this kind of material on a technically performant component in race conditions. Applying these materials to the rear brake duct wheel shields — with their intricate aerodynamic surfaces — demonstrates the technology can withstand the extreme conditions of Formula One racing, and supports its potential for widespread adoption across the sport.

“This project with Syensqo [Brussels, Belgium and Alpharetta, Ga., U.S.] highlights our commitment to reduce our environmental impact while maintaining the highest standards of performance,” says Alice Ashpitel, head of sustainability. “The fact that these materials have been derived from byproducts associated with the creation of bio-diesel is an added benefit and indicates the power of advanced sustainable fuels.”

Syensqo’s bio-based resin technology supported the W16 race car project. “By replacing traditional petroleum-based components with those derived from renewable sources, we are not only introducing circularity in our product design but also paving the way for future innovations,” notes Rodrigo Elizondo, president of Syensqo Composite Materials.
