Balloon Squeal Gone in 'Ds'?

Yeah, I had a P85D loaner, and didn't hear the squeal once. On the flip side you do hear the front motor constantly now under normal acceleration (under hard acceleration, you can't hear anything above the passenger screams). Under normal acceleration, you hear a quiet electric motor startup sound.
No balloon squeal in my P85D. As has been noted by others, all I hear in my P85D is front motor noise under heavy acceleration.

Also, I noticed there is no balloon squeal in the new high VIN S85 loaner I got today. In addition, I couldn't hear any noise from the motor (rear) at all under full throttle on the S85. They've really quieted things down.
Get er for a birthday gift...:wink:

For what it's worth, no squeal in our P85D, but we didn't experience a squeal in our P85 either...

It's good to get the sense that this has been dealt with. It's not a big deal but I love the quiet of my car. Anything that that detracts from it, is a negative. On that note, I had my winter tires removed today :smile:
Dancing with the notion of moving to a 'D'!
I had the ballon squeal sometimes in my P85. Then the DU was replaced, and it was even more frequent in the beginning, but then, the last months I haven't heard it at all. I suspected that a firmware updated fixed it.

But yesterday I got my P85D, and I hear a slight balloon squeal sometimes when launching.
