Front motor noise with hard acceleration.

[Bfitz510]

P3D with 600 miles. Since day 1 I’ve noticed that with hard acceleration I can hear a very high pitched noise coming from the front motor. It isnt very loud at all and can only be heard with the stereo off. It sounds like a the ringing you get in your ear sometimes, and goes away when I let off the accelerator. Is this normal for the front motor? TIA

It's probably normal. Is there any similarity to the sound you get with heavy regen braking?

Yes it is pretty similar to regen noise.

Ok, then it's just the electric motors doing their thing. You should eventually get used to it, unless, of course, it's a frequency that gives you a headache.

I hear this a lot cruising over 75mph and in hard accel in general. Seems normal.

Normal. Mine does the same when I get on it. Think of it as an EV exhaust note.

Normal - might be the inverters screaming. Honestly I wish it made more noise - I think the sound of the gearbox sounds pretty cool under hard acceleration.

Normal. Sounds just like an electric golf cart.

That is the ice breaking sound
