I don’t know if it is something they did lately in Q2 or something with all the 2021 models but I just switched from a 2020 to a 2021 and me and everyone else that has been in the new car have found it to be quite a bit more quiet than the old one. I also did not think my 2020 was louder than the other 2020 models I tried so I don’t think it had something wrong.
Is there any information on Tesla doing something for sound insulation apart from the double glass windows? Because this seems like it would be something more than that.
The 2021s also have a new version of the MXM4 tire (T1 version vs T0). There's not much out there about it but it's possible the tire is quieter also
