For sure. Acoustics glass on the back lowers the overall noise from the outside The new fabrics inside make the waves bounce less The new suspension surely helps aswell But in terms of added isolation I don’t see anything by looking at the parts catalog I will also wait for used rear...

The stock tires for the highland are the Michelin e. Primacy. At least in Sweden. The regular primacy is quieter than the Pilot Sport 4 that are known to be very loud. So when the reviews says the Highland is much quieter, is the tires doing most of the lift imo Some reviews even saying the...

Thx for sharing your findings. I’ll will add similar deadening and some fiber ontop the wells aswell I found some images on how the Mercedes EQC has its isolation. It is perhaps the quietest EV.

this video shows How they sit inside the dry space ontop the metal. The video also shows some kind of felt around the front liners. I don’t tecal seeing those before maybe is a new addition ? This is from the parts catalog and MY seems to have these foam parts on front and back

I just changed to winter tires, here in Sweden we need to change during winter And those are usually much softer The car is very quiet now to the point I can hear the motor wine in the highway the noise that is most noticeable now is the low frequency brumming that seems to come from the...

Thx for sharing I have a tip that might help identifying spots I recorded the loud noise when driving at highway speeds on rough asphalt I then use a portable speaker that plays good bass and playback the noise I then place the speaker on different locations to find where the isolation is...

I think one could add padded sound absorbing behind the arch liners? I see that Audi does this on their etron Also an interesting video from Mercedes on how they do their sound isolation I saw I have similar foam blocks on the Wheel wells on my car aswell

Thx for sharing George! Im also into making ours 2020 sr+ more quiet. Im wondering if you could share more pictures of the install, specially on the wheel archs and under the seat. How it looks after.

What kind of material do you recommend besides ceramic fiber? I really don’t want to mess with that, I saw that you had tested different materials before? I’m looking into PU foam to absorbe the noise rather than MLV that is a blocker, but I’m not sure what is the best bang for the buck The...

The foam parts are under the sound isolation section of the catalog

The new parts catalog for the Model 3 Highland is online and I was surprised by the lack of noise damping. From the test drives posted online, the consensus is that the car is not that much quieter than the older models. What we can see is that they have added some sort of foam blocks in the...

Thank you for sharing your insights. It appears that the wheel wells are the primary source of noise.I own a 2020 SR+ model, and the only modifications I've made are the addition of softer premium tires and retrofitting dual-pane windows to the front. These changes significantly improved the...

I just made the swap and wanted to share my experience. I got two used windows from a -21 model that I found online (I have a 2020) Installing Removing the inner panel is easy, I followed this video. Remember to disconnect/connect the light at the bottom to lower the window before testing...
