German racing series shifts to natural fiber application

German racing series DTM says the shift away from carbon fibers will be more cost-efficient, improve lightweighting and reduce the organization’s ecological footprint.

The German racing series Deutsche Tourenwagen Masters (DTM) reports that Bcomp (Fribourg, Switzerland), a manufacturer of lightweight solutions for the automotive industry, has been selected as a technical partner to boost sustainable lightweighting applications in motorsports. DTM says the partnership will open technical regulations to enable a material shift from carbon fibers to Bcomp’s natural fibers on mandatory composite parts for the 2020 season.

DTM says Bcomp’s powerRibs natural fiber has the same weight as the previously used carbon fiber parts, while reducing its ecological footprint, improving cost-efficiency and eliminating the risk of carbon fiber debris.

“With a high exposure to contacts, the DTM shoebox is a typical motorsport bodywork wear part that needs to be replaced or repaired after almost every race,” says Layla Wagener, sport and engineering specialist at DTM. “With Bcomp’s natural fiber technologies, we can achieve the same weight as with carbon fiber, while additionally taking advantage of the anti-splintering and environmental benefits. It is an ideal start to introduce Bcomp’s sustainable lightweighting solutions.”

Preceding the partnership, the first natural fiber DTM parts using Bcomp’s ampliTex and powerRibs fibers were successfully validated by BMW Motorsport and Audi Sport during the last DTM test in Jerez, Spain, and Vallelunga, Sicily. “Being a technical partner of the DTM enables us to showcase the full potential of our natural fiber technologies on the highest engineering level of touring car racing,” says Johann Wacht, Bcomp’s motorsport manager.

DTM says further application of natural fiber parts is in development and will be introduced by DTM and Bcomp throughout the racing season.  


  • The markets: Automotive (2021)

    Composites continue measured growth as the global automotive industry, driven by zero-emissions goals toward increased electrification, seeks to reduce vehicle weight and improve performance.

  • Auto composites quest: One-minute cycle time?

    Faced with high fuel prices and ever-more stringent restrictions on tailpipe emissions, automakers are taking composites into their own hands.

  • Composite flywheels: Finally picking up speed?

    A wave of new composite flywheel developments for bus, rail, auto, heavy truck, construction equipment, and power grid support promises fuel savings, improved efficiency and reduced emissions — i.e. sustainability in the global quest for more energy.
