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:

Hi Wallace,

We actually looked into this in anticipation of requests like yours. That and we were thinking of this for marketing purposes, etc... Because this is a safety feature of the car, it will not be something we can change on our own or at the dealer. What sound(s) would you use?

OK, I am expecting my smart Ed in May.  Anyone have a way to put "optional" sounds into the Pedestrian warning sound (code B53)?  It should be as easy as downloading a song (but I bet it isn't)?

I don't think you'll hear it inside the car. I drove the smart ED and a LEAF and I didn't hear it in either.  Better watch out for deer. Too, lol

I wonder how long it will be before someone can tell me which fuse to pull to turn that feature off.  I don't deal with pedestrians almost ever and I consider the quietness of an EV to be a positive selling point.  Making something quiet nosiy isn't a bonus for me.

Why not play a nice theme song to 'warn' people you're coming, like...

♫ "Here I come to save the day! That means a smart Car is on it's way!" ♫  lol

Mighty Mouse would be proud!
