The iFE.20 is the first BMW race car fielded by a works team with parts made out of renewable textile fibres – making it a pioneer for series production.
Compared with carbon, flax has greater absorption and greater impact resistance, which can be advantageous on the street circuits with their bumps and crash barriers, on which Formula E takes place. The same is true of contact with other cars during races.
The use of the material is being expanded to other BMW Motorsport race cars.
“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 an innovative 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.”
BMW i Andretti Motorsport and the iFE.20 got off to a successful start in Season 6 of the ABB FIA Formula E Championship with their victory in Saudi Arabia last November.
Briton Alexander Sims heads into the new year and the next race in Santiago, Chile, at the top of the driver’s standings, backed by a winning car.
