Extra layer of UV/IR filtering in the glass because with a glass roof it can get extremely hot inside under the sun and this is used to help mitigate that consequence. Edit: Its not just Tesla though, you see it on other glass roof vehicles, sun roofs. You can see it strongly on higher enc luxury cars like Mercedes (theirs look more blue/purple), especially in the morning with a light film of condensation.
It's to keep the ~~UV~~ IR (thanks caj\_account) rays out. They no longer have this on any of their models afaik.
Should be IR not UV, UV generally cannot penetrate the surface well, but IR cuts through everything. Edit: basically every time I ride in a 3/y in san diego uber and burn my scalp off...
Damn it, you're totally right. Not sure what I was writing.
no worries dude :)

It’s just a lot for all the endless demand I heard. Similar to their new promo for 0% at 72months and no money down for leases. Endless demand.
My 2018 Model 3 Performance has this. It's only visible when wet. Drive through people comment on it every time it's raining.
Older models had glass that turned that color in rain etc. I don't think that's a new car.
Partially false. Untreated soda lime glass is still nearly transparent for UV light between 350-400 nm ([source](https://www.researchgate.net/figure/Transmittance-spectra-of-a-regular-soda-lime-glass-control-glass-and-a-soda-lime-glass_fig2_317383431). Those are ionizing radiation and can cause cancer
How’s car glass untreated SLG? This is such a reach just to force yourself into the old conversation acting all smart and useful. Windshields block 94% UVA and all UVB rays. Side windows block 71% https://pmc.ncbi.nlm.nih.gov/articles/PMC12037386/
Really? That’s window tinting applied from the factory.
The conversation is about treatment to glass so yes it is very relevant. Your own source indicates that using tempered glass blocks only 21% of UVA (fig. 1), this is the range i was talking about. Also, the useful blocking of UV occurs at the middle layer, not at the surface, so your comment of UV being absorbed at the surface is completely wrong. I also dont have to act smart when I have a PhD in physics...
My comment says UV cannot penetrate well. Where did I says absorbed at surface go away typical redditor. I have a PhD also. I know what I’m saying.

"UV generally cannot penetrate the surface well" your comment word for word. It does penetrate the glass surface well as the transmission is over 90% on the 2 sides. It seems that your dissertation committee should not have let you pass.
Fuck off dude
Totally freaked me out when snow on the roof turned these colors.
I have a 2026 Model S and noticed this the other day while washing it. Kind of concerned me a little when I saw the red hue. I thought I might have applied something to the glass that created an adverse chemical reaction. It “went away” once I dried the car…thank goodness. This helps explain what I saw. Thank you, OP.
Somehow musk has reinvented glass and now it rusts
