Heat rejection of sunroof top glass

[CTruck_BMW]

Does anyone know the heat rejection (IR rejection) if the top glass on the Model S? I know they switched to a new one a few months ago that lets 5X more light yet with same heat rejection.

Many people from the MX group measured it as 98% IR rejection, same for some Model 3 measurments. Does anyone know for sure what the IR rejection is for Model S?

I can say with the 2020 Model 3, we had to put a shade under the glass to survive the brutal Texas summers. It was roasting our scalps. With the 2023 Model S with the darker glass version, we don't need the shade.

Wish there is a documenter IR reflection % somewhere.
