BMW GINA fabric

Hi, guys!
Does anybody know what exactly material BMW used for its GINA?
Is it a kind of sustainable material? And what about the fire resistance?

i read somewhere that it’s neoprene based…dunno what exactly it is.

Since it is in Germany I would think that it may have to be fireproof. It is a prototype so it may be exempt from Germanys fire-proof material laws (sofas and other things must be fire retardant).

my guess is that it’s a polyurethane-covered spandex.

That’s what Wikipedia says too…

If you can still find an issue of car styling 186 they talk about it in there.
