Modeled on nature: New MAHLE fan for e-vehicles

MAHLE is presenting a world first at the IAA Transportation 2024 in Hanover: a bionic high-performance fan which makes commercial vehicles significantly quieter. The fan was developed for particularly demanding fuel cell and battery electric vehicles. When optimizing its ventilation blades with the use of AI, the MAHLE engineers took inspiration from the wings of an owl: One of the quietest birds in the world, the owl’s plumage has a noise-reducing effect. The bionic fan blades can reduce the fan noise of a truck by up to 4 dB(A) – this is equal to more than halving the sound output.
