Audi stopped Q8 e-tron production in early 2025. I don't know how much allocation the US has had of the semi-replacement (S)Q6, and A6 was not launched at all.

Q4 is a bit weird, since it's just a more expensive ID. 4, and not exactly more premium. Actually less premium feel than the sister car Skoda Enyaq, but that's not available in the US.

They're a bit out-of-phase with BMW and Mercedes right now, who just opened the books on their new platform cars. Perhaps you could argue it was bad timing with the Q6 being a bit of an "inbetweener", but the PPE platform was delayed, to be fair.
