I think many of us are guilty of thinking only of us and maybe our passengers when talking about the smart or any car for that matter. How does the car handle? How much stuff can I fit inside? What gas mileage does it get? But, how often do we think about the pedestrians and the safety aspect around not only keeping the driver and their passengers safe, but those on the outside of the car. This is ESPECIALLY important when talking about an electric car and how insanely quiet they can be at speed. This is why Daimler AG has engineered the “sound box” or “Pedestrian warning sound (code B53)” into the all new smart electric drive. As you can see from the pic, it’s a small black box that is located behind the right headlamp assembly. This is what truly gives the smart electric drive it’s sound. Without it, it would be so very quiet, that pedestrians would have a near impossible time hearing it coming should they not be looking.
Here are the sounds from full acceleration to constant driving to braking and smooth driving:
