Unlike MB and Audi, BMW are invested in electric tech and have already been for a while with the i3 (both full and hybrid trims) and also the X series hybrid SUVs. So for them battery tech is a "solved problem". They already have a production capacity of 2.5m/yr and likely will keep the same capacity in the gas-electric transition.

Not that the GTR was absurdly expensive, but i don't think that car changed the perception of Nissan much.
Also both Audi and MB have hybrid and full EVs (well VW who own Audi, and share the same platforms).
it's more of a cost-efficient, tuner friendly car that's loaded with tech, that can take-on pretty much anything, while offering the reliability of a Nissan.
far too many people keep hyping numbers of Tesla's preorders or even sales of S & X while completely ignoring they don't even come close to equaling single lines of some other brands who do this year in year out
But Mercedes, Audi, BMW, etc., have an incredible amount of brand demand too. They'd have even more if they cut out their entry-level cars and only sold flagships like Tesla has done up to this point.
The reality is building a desirable car brand is not that hard. Just make absurdly expensive cars that few people can own and you're halfway there. Then slowly introduce more affordable models.
