Racing cars with body parts made from renewable raw materials

The Porsche 718 Cayman GT4 Clubsport MR will tackle this year’s Nürburgring 24-hour race featuring a complete body kit made of natural-fibre composite materials for the first time.

Since early 2019, Porsche manufactured the two doors and the rear wing of the small series racing vehicle out of a natural-fibre mix, sourced primarily from renewable raw materials. Now for the first time, the front and rear aprons, the front spoiler, front and rear lids as well as the mudguards and diffuser including the aerodynamic fins are also made of this regenerative material. These materials replace the metal and plastic injection moulded components of the production sports car. In terms of weight and stiffness, the recyclable natural-fibre composite materials of non-structural components share properties similar to carbon-fibre composites (CFRP) and meet the same high safety and quality standards. Natural-fibre composites can be manufactured more economically and with less energy.

Farmed flax fibres serve as the basis of the sustainable natural-fibre composite material – without conflicting with food crops. This development began in 2016 with collaboration between Porsche, the Federal Ministry of Food and Agriculture (BMEL), the Fraunhofer WKI and the Swiss company Bcomp. At the 24-hour race, the team Four Motors joins forces with Project 1 Motorsport to take the natural-fibre 718 Cayman GT4 Clubsport MR through its first test at race speed.
