GT3 version when, though?
Never, because F1 team which nobody asked for or wanted. Audi's whole thing was sports cars.
Also I bet VW's bean counters are happy they can just point to the Temerario and say "this is our GT3 offering now if you want to buy one, go there instead".
As for this car, it's nice there's a new mid-engined supercar from Audi in any capacity, but it looks terrible imo. The Concept C was already a little odd but looked mostly ok, this is just a straight-up Minecraft car. Looks like it came out of the 3D printer in Marathon or something.
No joke I think the new Ferrari Luce looks better than this one. (I actually don't even hate how that car looks lol unlike most people). But they really took the R8, one of the best looking cars of its time, and said "nah cube on wheels" and put this crap out.
Also I hate that it's got a limited LaFerrari style production run instead of just being a regular Temerario twin. So that also hurts its non-existent prospects of ever being turned into a race car.
I really feel like every single major car company is having a massive identity crisis trying to figure out this whole electric car thing, it's really only Hyundai that's doing it well imo. Audi threw out all of their sporting credibility with enthusiasts by going to F1 and killing all of their gas-powered performance models, Dodge killed their V8 and are trying to scramble to revive it, Porsche killed a bunch of their non-911 models and are scrambling to revive them, Jaguar went crazy and threw out literally their entire brand, Ferrari put out a Telsa rival as their first electric car instead of a more traditional supercar, and so on.
