BMW expands its Research and Innovation Center to charge the quiet EV revolution

• BMW’s Aeroacoustics and Electric Drive Center features the world’s quietest wind tunnel for precise EV noise testing.
• Engineers use advanced tools like acoustic cameras and laser vibrometry to refine acoustics and vibrations in EVs.
• The facility’s labs develop high-voltage batteries and inverters, advancing electric vehicle technology with premium quality standards.

The science of silence: BMW opens new Aeroacoustics Center in Munich to propel EV innovation

BMW has taken a major step in EV innovation with its new Aeroacoustics and Electric Drive Center (AEC) in Munich. 

The centrepiece of the AEC is the world’s quietest wind tunnel. The background noise level is as low as 54.3 dB(A), that’s softer than a quiet conversation. With this silence, engineers can accurately measure and minimise wind and road noise. Road noise has long been a comfort issue for EVs, which lack the masking sounds of traditional engines.

Inside the AEC, advanced tools drive precision. A 216-microphone acoustic camera maps tiny noise sources. Laser vibrometry measures vibrations across the vehicle’s surface without touching it. Developers can even isolate wind and rolling noise to refine each component.

Daniel Böttger, Head of Complete Vehicle Development at BMW AG, celebrates the site:

“Quiet is premium. Our focus is on meeting the premium standards of our vehicles. An important part of this is acoustics — particularly for quiet electric models.”

Beyond acoustics, the facility is accelerating the future of EV technology. It includes prototype labs for building high-voltage batteries and inverters, essential components for electric motors. Clean-room conditions ensure these parts meet the highest quality standards.

BMW has found success in its EV focus, reporting a significant rise in EV sales this year. By combining groundbreaking aeroacoustics with EV innovation, BMW is setting new standards for silent, premium EVs.
