And as far as I know, the polestar is designed as an EV too.

There is no body designed around the constraints of routing exhaust or transmission elements. It is just an empty box.
The first polestar built off of a dedicated EV platform will be the polestar 3.
My Polestar 2 has a glass roof too. I think it's part of the "plus" pack?
