Singing at 65-70 mph

[ColdCase]

I’m not sure I’m in the right section, but let me ask this here before chasing my tail with more test drives. I drove a Macan 4 on a highway and observed it singing between 65 and 70 mph. It is similar to tire noise or remote control model motor noise. Anyone else?

The Macan had 21 inch Michelins. I’m not sure what driving mode the SA selected but It was a mode that will gently slow a bit when the throttle pedal is released, not a coast mode. The singing was louder on deceleration. The SA thought that stretch of highway was noisy, so I didn’t pursue it. I’ve since driven my other cars on that stretch and they were quiet, no songs. So I now have second thoughts. But before I go back and drive another sample I thought I’d check in here if this is a known issue. My forum search didn’t find anything.

Tires will make noise. sometimes it's more noticeable than other times. Try not to let it consume you... This is the exact reason why I opted for sport sound and Burmester stereo.

What is your tire PSI set to?

This was a fresh dealer demonstrator. I'm pretty sure they set these up properly, after all it is a Porsche center, but I didn't double check. I know it is hard to tell over the web but I've been a car enthusiast for 50+ years. This was similar to tire noise in some ways.

Ah, you mean the brake recuperation / regen. the noise is normal.

With EV cars it’s easy to notice “sounds/noises” never heard before.

Perhaps for Porsche's system, but this car was singing annoyingly during a specific speed range at cruise and on/off throttle, just more noticeable off throttle. If thats normal for a Macan, it is going to be a deal breaker.

But I think I'm hearing here that this just may be a one off car. There are several discussions about noisy tires elsewhere, however.

As background, if it matters. I've been driving a Mini SE EV for near four years. So I'm familiar with how a BMW tech based EV drives, sounds, and feels. I don't recall the Mini singing to me. As the tires wear there is more and more noise, but thats across the board and not at a narrow speed range.. The VW ID.4 Pro I test drove awhile back doesn't sing nor the one my sister owns. Small sample size I know.
