This is probably an odd question, but many of you here already own EV's so maybe you can answer it for me. My neighbor has a Lexus battery/electric hybrid and when he is driving in or out of the neighborhood and it is running on electricity, it make a very audible whine. It is actually much louder when the ICE engine is running vs the electric motor. But I do not recall fully electric cars being loud like that... Any explanation? I think that I read from the reviews here that the Hummer is actually fairly quiet.

I think I saw somewhere that there is an audible noise transmitted out of the Hummer up to 25mph. I know it is a requirement for EVs in Europe to help people, especially thought with sight impairment, know that an electric car is driving nearby.

Yes it's a law in the United States that EVs have to make a pedestrian alert noise up to 19-25 MPH so those hard of sight can hear the vehicle approaching.

The laws have gotten stricter over time and newer cars have to be louder, as compared to older ones. My Mach E (2021) is louder than my Bolt (2017) and also beeps when it is in reverse.

I got my first EV in November, a 2021 Mache E, and I hate the fake noise. I covered the speaker with cardboard but it is still too loud. I am planning to put a volume control on the speaker so I can turn it off, or lower the volume when I want. It will probably be off most of the time.

I bet the Hummer will be just as easy to modify. It is just a speaker. If you don't like it, replace the speaker with a resistor, cover it with cardboard, or put a volume control on it like I am going to do. You can't cut the wire to the speaker because then you get an error about the speaker being disconnected.

It's a simple fuse in the fuse block... no need to do any wire edits....
