This post is created for a discussion under another post.

The content of my original post was about a dicrepancy of the manual claiming the car having laminated side windows and the actual car having only tempered glass. It was noticed by another Chinese owner and I extended the discussion. Part of my original post was:

“...... Our newest finding is about the glass.When some people complained about the level of noise when driving on highways, people checked their windows and found out they are only single tempered glass although in the driver's manuals it clearly stated that "The windshield, panoramic roof and door side windows have laminated glasses. Laminated glass is reinforced,..." Even the sales were saying the windows would be laminated glass -- I specifically remembered that because I asked that during a test driving session. Wonder if the cars shipped outside of the country has the same issue?Our glass were manufactured by Fuyao, with a product code 43R000055 meaning its a single tempered glass. Is it the same situatiion in Sweden, UK or the US?”

I wonder if this issue is global and involves all the car that has been delivered. If so, there is something we should speak with the polestar management about since laminated glass are indeed are a lot better to only tempered glass. Please speak your mind under this post. Also participate in the poll to determine on the reality of this issue

Good point! Here the text from the user manual:

Crikey, this is a bit worrying and a very poor bit of mis-selling if it has been consistently done... Mine arrives next week.

I asked a Dutch guy to check the glass in his side windows and they are also ‘tempered’ so i assume all the P2’s in The Netherlands are delivered with the cheaper tempered glass in the door-windows and not the promised laminated glass (which was announced as ‘better protection against break and improved soundproofing’). Which is dissapointing from Polestar.

(Btw: the Dutch glass has the same Fuyao productnumber as in China)

My money is that this is a simple mistranslation that's slipped through - it should say tempered, not laminated. Laminated is substantially heavier and more expensive. On the other hand, tempered glass doesn't provide any soundproofing, so... worth picking up with them, but all that will happen is an apology, a correction to the website and a legal thing pointing out that all specs are subject to change (standard Ts & Cs).

I am afraid you are right 😢

Honestly I don’t think I’d want laminated side windows on a car that’s already exceptionally quiet (you can probably do more for noise by opting out of 20” wheels). Tempered glass is lighter (range), and actually stronger, but shatters efficiently and generally without sharp edges when it takes a good hit, meaning you can break it in an emergency. Laminated glass is good for thicker windows you definitely don’t want shattering in your face with glass flying at you (like the windshield), but is more susceptible to dings/cracks. A lamination layer does not make the glass “stronger” per se (the opposite, actually), but if something does happen it just sticks to the film instead of falling apart. Tradeoffs.

That may be true and an advantage(?) but i quote two others in a thread about this topic:

“Laminated side glass is permitted in Europe - it's a feature on many high end vehicles (Volvo, Audi, Mercedes)”

“Double paned windows actually do make a difference. In fact Tesla, responding to complaints about noise in the cabin of the Model 3, is now adding double-paned side glass as part of a refresh for the M3. Quieter, upscale cars, often do have double-paned side glass windows.”

And Polestar self said this about their laminated glass: “better protection against break-ins and improved soundproofing in the passengers cabin”

Considering the manual talks about dangers of exhaust fumes in one section (!) I think it was written by some school kid on work experience.

I own other cars that make mention of features in the manual that never made it to production too... they caveat with the standard ‘errors and omissions accepted’ and unless your sales documents make specific mention, the manual could say it converts to a submersible if you ask Google nicely yet you’ll get nothing more than ‘please disregard that section’ if you question it.

Completely agree, unless you're in the habit of throwing steel balls at the side windows of your car 😉, laminated side windows are unnecessary, particularly where wind noise is already whisper quiet as it is in the P2.

Admittedly, apart from some 'spirited overtakes' 🤫 I haven't taken mine up to very high speeds yet, but in the 60-70mph range wind noise is way less of a factor than tyre noise and what the road surface is.

Actually, I disagree. I understand it depends on what you're coming from. In my case I'm moving from a Volvo V90 T8 (a PHEV with similar power to the P2 but most of that power comes from a turbocharged AND supercharged engine). Something I noticed during my test drive is that the P2 is noticeably louder than the V90 and of course this mostly comes from road noise. Laminated side windows would be a real help in keeping it quiet.

For me, when we test drove the Polestar 2, the most disappointing thing (range aside) was the amount of tyre noise, even on the standard 19" wheels. The car is some way noisier than my old Ampera and no quieter than the Kona even though that has proper tyres on (we binned the supplied Nexens three days after the car arrived). I was hoping for rather more serene silence but basically the wheels are too big for a quiet ride.

I would think that budget sound isolation would be a bigger factor than the wheel size. When I change my current car's wheels over to winter tyres with studs, the road noise goes up, but not all that much, the sound insulation is just that much better.

The road noise I heard during the test drive is one of the reasons I recently changed my polestar winter wheel order to nordic friction tyres rather than studded.

Apologies for the ignorance, but why are large wheels/tires noisier than small ones?

'Not an expert, but a smaller rim means a larger tire sidewall height as the overall diameter of the wheel needs to be the same, regardless of rim size.

With a larger tire sidewall height, there's likely more ability to absorb the high-frequency vibrations coming from a less than perfect road surface and the fact that tires have knobby bits that also produce a high-frequency sound.

So that's my speculation.

A lot of it depends on the tread pattern and stickiness of the rubber. But in general the more rubber (tire patch) you are putting on the road and then pulling up off the road, the more noise will be generated.

i thought the explanation was more that the longer side wall of smaller rimmed tires helps to absorb/dampen the noise coming from the tire/road interaction?
