Thermopane windows?

We don't know. R1 has double pane, at least up front. I haven't sat much in the rear seats of my R1T to know. Might check later today....

Shouldn’t ever be judged as a deal breaker. There are multiple ways to reduce NVH. Those who use double pane glass do it because windows are closer to ears. That allows them to skim on insulation everywhere else. Just because one brand uses it, don’t assume it to be the better car. Work in the wind tunnel—even minute changes to surfaces and cutlines—can reduce noise. Some brands skip this because it’s time consuming and expensive. Example, first generation MB CLA has terrible wind buffeting even with all windows closed; despite being rounded and low slung.

Laminated front side windows are pretty common on a lot of vehicles, even the mainstream ones. I think our 2017 Mazda has it too.

R1 has laminated glass on the windshield, roof, and front sides. Rear sides and rear glass is tempered.

I would be surprised if R2 doesn't have the same setup - it's become pretty standard for new cars in the last few years.

A lot of it has to do with safety rules that were changed around that time so this was one way car manufacturers could address it. But laminated is not technically required so there might be other solutions I don't know about.

FMVSS 226 Ejection Mitigation preventing passenger ejection through side windows during rollovers or side impacts.

Interesting. I didn't know about this. But some vehicles included this in higher trims only. So noise reduction was likely a bigger factor for some of the vehicles.

More than just sound insulation, thermal insulated glass would be great feature to have on the windshield where the majority of the heat comes in.

I have this on one of my vehicles and it is very noticeable difference to keep the cabin temperature down in the sun/when hot. While I have not experienced it with this vehicle, I was told that it also help keep the heat in the cabin in a very cold weather (I live in SoCal so its never really cold).

In either case, thermal insulated windshield (and potentially the glass roof) would make controlling the cabin environment much less demanding and reduce the HVAC drain on the battery as well.

To keep the price of R2 down, it should be an option rather than a standard equipment.

Double pain windows for the Rivian would only help after they address the external noise issue created by the present design of the front driver and passenger windows. The sharp angle of the window reduces the ability in reducing wind noise. Look at all other cars. A sweeping angle is preferred

Yeah, but it looks cool. lol

Eh. Not every R1 has this problem. It's more about controlling variances on the production line—fitment/alignment of doors and how well the seals are installed. And some of the cases aren't because of the doors, but misalignment of the trim piece between windshield and roof. In short, tolerance stacking and quality control.

Design engineering should take information from manufacturing and quality control to instill continuous improvement. I have seen many an engineer not "use" the product or design they propose and end up redesigning the part because a failure from a difficult assembly

That is just one of the things they could do but not the only thing—to ensure whatever rolls off the production line is everything they intended on the "drawing board". Mine rolled off the line and was delivered with all four doors out of alignment. And even then there was no wind noise like some described of theirs. While I didn't have the issue, the misaligned doors for sure isn't what the designers and engineers had in mind (because SC agreed they were out of spec and corrected them, for free, well after the 1 year adjustment period). That points squarely at the manufacturing side of the equation—that practices over there need to tighten up. And RJ's recent posts suggest they've implemented new tech to address that for R2 production.

You insist the shape of the windows are solely responsible for the noise issue. That would mean every single car produced would have his inherent problem. That is clearly not the case.

Have any of the actual in the vehicle reviews mentioned double pane windows?

Oh, ok
