Smart Fortwo ED Purrs
Should an electric vehicles pedestrian warning system emit a sound that's more or less in tune with the performance of the vehicle?
I Get a Huskier Tone
Daimler seems to think so and, as such, fitted the Smart Fortwo Electric Drive with a pleasant "sonorous purring" sound, while electing to give the Mercedes-Benz SLS AMG Electric Drive a huskier tone.
Christoph Meier, a sound engineer at Daimler, is the man responsible for choosing the EV sounds. Meier says the Smart ED has a higher pitched noise, which he likens to "sonorous purring." Meanwhile, the brutally powerful AMG ED gets a huskier tone.
Daimler is on the side of the fence that thinks EVs need noise. As Meier stated:
"People expect some exterior noise from a vehicle, because we all grew up with the 'vroom vroom' of combustion engines."
Like it or not, regulators across the globe are expected to make these pedestrian warning sounds mandatory, so what kind of sound would you prefer? A gentle, soothing one? Or something more robust?
