The ID badge is there to distinguish the electric range while ICE cars are still available, come 2030/35 there will no longer be ICE cars being produced (in Europe at least), they won’t then refer to all their models as ID, how dull would that be, this isn’t Volvo you know!
, there will be no need to distinguish them, as all their cars will be electric they can start using model names only as the power train is a given, at the moment ID is purely marketing and allows the consumer to see easily what they are buying, the same will happen to the etron badge with Audi, they will drop it, Golf, Tiguan, Passat, A3 or whatever can all stay named as such, the ID power train will be developed and built into whichever model they wish, the Golf is not dead, there will be an electric GTI and R, mark my words.
