The high-pitched whine during acceleration...

[J in MN]

Oh well, I hear "whirrrrrrrrrrrfff". Yes, a bit like a balloon letting out air through a kazoo... :redface:

At 4:08, most of the tone is 1000 Hz, and then it ramps up to about 1125 Hz at the end. At 5:00 it starts at 1000 Hz, drops to 980 Hz, then ramps up to 1125 Hz.

I'm not Doug, but I drove the same car you did and we-all heard the noise very clearly and repeatedly.

Maybe you weren't putting the pedal onto the floor?

Hmm. I definitely punched it several times. Did have the roof and windows open for most of it. Maybe that drowned it out.

I think these are different noises. Under high acceleration, I hear a very pure, high pitched tone, octaves above High C; I'm guessing about 4kHz. When really floored, I barely hear another pure harmonic. It's the car singing to me! Definitely not "balloon" noises.

You can here it pretty well in my test drive video (no music on, shotgun mic):

First time I've actually heard what people are talking about in these videos. Thanks for sharing.

It is definitely there but only for a short time and at the start of max acceleration. Don't really hear it when playing music.

Yikes, that sounds pretty terrible in that video. I have my first test drive Monday, I'll have to see if I can duplicate it.

 

[cinergi]

Yeah, I have it. And I'm kinda hating it. Like, really hating it. :crying:

Look forward to it. I've heard a variety of reports about whether it's still audible. Even during the Get Amped tour videos it wasn't always audible under maximum acceleration, but I've heard recent reviews that mention a sound from the "power electronics". So I'm curious as to what you will find.

Serious? Bad?

 

[kevincwelch]

I didn't notice it in any of my test drives, but I didn't really gun it at any point. Is it something in both the P85 as well as the S85?

 

[Doug_G]

If I had to guess, the whine is coming from inductors or transformers in the drive inverter. There's a fair bit of electromotive force in a coil when you put a lot of current through it, and that can cause the windings to vibrate if they have any wiggle room at all. This could easily be variable from unit to unit.

 

[archibaldcrane]

I'm curious if it is in the standard models without the inverter.

I like it. It's turbine-like and represents the new motive force Tesla is all about.

If I'm driving with music off and enjoying the serenity, it gets interrupted with that noise when I'm doing stuff like accelerating onto the highway from a ramp. With a silent interior (music off) it's very very noticeable. I need more time with it but it really "upset" me when it happened. I'll report back after having dealt with it several more times. And BTW it doesn't require flooring it to cause it. It just only happens inside a certain window of the speed you're traveling.
Would be very curious to know if it happens in the non-perf version.

Cinergi - It bothered me a lot during my test drive in DC (Performance). I've been hanging on the forums for word that it is no longer an issue. I'm really sorry you have it. Rumor was, a while ago, that TM was working on it (it being an electrical connector(?)) but I haven't read anything recently. I do indeed hope this is something they can quell. My perf arrives in, hmmm, January.

 

[dsm363]

I've noticed it but doesn't really bother me as much. When I floor it the acceleration grin overwhelms any noise I hear. I do hope they are able to fix it as I can see how it might bother people.

 

[cinergi]

So I brought this up with the ownership team and they're telling me it shouldn't be occurring and will be scheduling service to take a look at it. I'll report back when I know more.

Every S has an inverter. The Performance has a hand-wound / higher quality inverter.

So let's call complaints about it "The Whine Whine". >;-P

I definitely heard it in the Blue non-Perf during the Chicago Get Amped. I did not hear it in a later test drive of the Grey Perf at Santana row, interestingly. Though maybe that car did have it, and I somehow missed it while talking to the Tesla rep or something.
