    With how quiet the car is, will it need to generate artificial sounds to let pedestrians know it’s there? Not sure if there’s any requirement for that but thinking for blind pedestrians or similar use case.

    Some jurisdictions require by law that EVs generate these sounds. Aptera will have the capability to comply with the law and also be a factor in having a safe car for pedestrians as well as occupants. Aptera will look out for everyone!

    In the US it’s actually a Federal requirement that all EVs and Hybrids produce some level of warning sound up to 30 kph/18.6 mph: https://www.federalregister.gov/documents/2018/02/26/2018-03721/federal-motor-vehicle-safety-standard-no-141-minimum-sound-requirements-for-hybrid-and-electric

    I work with a number of visually-impaired individuals and they’ve explained that what they hear from motor vehicles is, first and foremost, tire noise. With ICE vehicles the majority of engine noise is emitted from the rear of the vehicle, as exhaust: My VI friends say that they can tell if a car is ICE or EV only as it passes.

    Plus, as all ICEs make more-or-less the same sound, people can identify that sound as “engine noise”. With every EV making its own synthesized sound – and all of those sounds being different – it will be difficult for people to determine just what they’re hearing.

      When the SOL passed me “at a hi speed (mph not known) the in-wheel motors made a winding sound outside/around the vehicle. Granted this is just an alpha vehicle and the front aero covers were not on so the front wheel cover are open…. We shall hear/see…..end of 2021 where we on on this one!

    I hope they pay attention to noise deadening. The one thing I really don’t like about my Model 3 is how noisy it is, it has a tremendous amount of road noise. My Volt was much quieter and that was essentially a low end Chevy.

      The newer builds of the Model 3 are significantly quieter – and will be quieter, still, as they switch over to cast subframes. The addition of acoustic glass in the door and roof windows REALLY makes a difference.

    Yes, it’s a legal requirement in the US. Here’s what my Niro EV does. It has a speaker in the front bumper.

    How about a sonar Ping sound that increases in frequency as you get closer to any object behind.

    ping…….ping….ping..pingpingpinping

    It should not be hard to give us a choice of sounds.

    I would like to have a choice of the Jetsons car sound.

      I would like that very much, myself – although I fear it may be copyrighted, this video notwithstanding… https://youtu.be/LnT1VgeXOF0

      I’d pay for a Jetson car sound upgrade. 😆

    This is the AVAS (Acoustic Vehicle Alert Sound) of my Honda Clarity pulling into and out of the garage. The only place you can really hear it is when it’s indoors – and it cuts out at 12 mph. The 2020 models, though, have the same sound only significantly louder – and it plays until the regulation speed of 18.6 mph (30 kph) is reached. https://youtu.be/2kdb3D29Wmc

    I would just like to be able to upload a custom sound…

    With our Prius the main problem was when backing up. Toyota put a sound to let you know you were in reverse but it was not audible outside. So first I put in one of those little 12vdc beepers wired in parallel with the left backup light; however people still walked directly behind the Prius when I was backing up. So I went to Amazon and ordered the Wolo BA-70 that says: “Attention Please. This Car Is Backing Up.” repeatedly until you shift out of Reverse. This I was able to mount inside the bumper cover and again wired it to the left backup light. The result? People STILL walked behind me when I was backing up! Never underestimate the stupidity of the average human.

    That said however, I’ll probably put a Wolo BA-70 in the Aptera.

    Hi, I’d like to see that feature in the final product.

    It’s very easy to implement. So if you have other feature that easy, ask it here, hoping Aptera will take them in account.

    • Feature 1=

    I will have to drive (slowly) in small streets among pedestrians very used to abuse (their right of use the street).

    If pedestrians hear a horse coming behind them, they will have the reflex to move away.

    ( If a car is absolutely silent when it moves, then shit happens. )

    So I need a button that will generate that sound outside (accorded to my speed, kiticlop, kataklop’, dratakla’ …)🐴

    Easy, no ?

    Dumb question, but I just don’t know. Do all EVs make a slow speed sound as they slow down and speed up at every intersection? Seems like I have only heard a few compared to the number of vehicles I have seen on the road.

      That’s the current law for electric cars. I doubt the law applies to motor or auto-cycles.

      It didn’t exist in 2013 when my Chevy Volt was made, so that noise making law is fairly recent. (I love sneaking up on people in parking lots.😁) Instead, the Volt came with a special pedestrian horn that wasn’t so scary loud as the normal car horn.
