10. Natural fiber racing
One normally wouldn’t associate a high-performance racing car with flax fibers but Porsche has proven the sustainably farmed material’s mettle in one of the toughest endurance races on the planet — the Nürburgring 24-hour race.
Natural-fiber composite materials replace the metal and plastic injection molded components of the production sports car. In terms of weight and stiffness, the recyclable natural-fiber composite materials of non-structural components share properties similar to carbon-fiber composites (CFRP) and meet the same high safety and quality standards. Natural-fiber composites can be manufactured more economically and with less energy.
