The BMW iFE.20, which claimed victory in the recent ABB FIA Formula E Championship race held in Saudi Arabia, is the first BMW racing car to employ a part made from renewable textile fibres – a cooling shaft made of flax.

“The flax cooling shaft that we use in the BMW iFE.20 is further proof of the hugely important role of BMW i Motorsport as a tech lab for the BMW Group,” said BMW Group Motorsport Director Jens Marquardt.

“We are consistently using Formula E as a platform for series development – in this instance for testing flax in extreme weather conditions. What’s particularly remarkable is the fact that in some areas this renewable material even has advantages over materials established in racing, such as carbon. Our ambition is to always use the best suited material for each part.”

Compared with carbon, flax has greater absorption and greater impact resistance, which can be advantageous on the street circuits on which Formula E takes place with their bumps and crash barriers. The same is true of contact with other cars during races.

Expansion of this concept to include other BMW Motorsport racing cars is currently already in the development phase.
