Mercedes Gives Its Electric Cars Pedestrian Warning Tones
Christoph Meier, a sound engineer at Mercedes-Benz parent Daimler AG (DAI), typically spends time making engine noise less jarring. For the carmaker’s new electric models, he’s had to do the opposite -- create sound.
For Daimler’s e-Smart city car, Meier and his team invented a “sonorous purring” that was pitched higher than conventional vehicles, while Mercedes’s 416,500-euro ($569,600) SLS AMG Coupe Electric Drive gets huskier tones to reflect its power.
“People expect some exterior noise from a vehicle, because we all grew up with the ‘vroom vroom’ of combustion engines,” said Meier, who oversees 250 people as head of powertrain acoustics at the Stuttgart, Germany-based company.
