Something to keep in mind here is that after the end of 2024, a vehicle containing any critical battery minerals or components sourced from foreign entities of concern (Russia, China, Iran, and North Korea are currently listed) will be entirely disqualified for both halves of the credit.
Disclaimer that I'm pessimistic, but we truly do not even know if the Model Y will get the $80k SUV limit and here's my reasoning:
I couldn't find a single competitor to the Model Y -- in terms of size, seating, etc -- that approaches $80k. A Model Y LR was down below $50k in 2021 before the crazy price hikes, and neither the LR or P approach this limit even at the much higher prices. An $80k limit on vehicles of this type/size seems gratuitous and IMO doesn't make sense when even the highest end luxury small SUVs are still far below $80k.
I think it's possible the Model Y will be held to the $55k limit for "Other" vehicles along with the Model 3. The X could be called a real SUV and might get the $80k limit, but generally I suspect the higher limit is for very large SUVs and trucks that will require very large battery packs and consume tons of power -- the Cybertruck would also fit in that category.
I'll be surprised if the $80k limit is intended to subsidize ultra luxury fully loaded crossovers and small SUVs, because that's what would be required to hit $80k in a vehicle of this size, but I guess we'll see.
