Tesla had to do this. They've filled the order backlog of customers who were willing to pay more than $35K. They still have many on the list who are only willing to pay the original $35K. So it's sell at $35K, cut production, or park the unsold cars in a lot. Happens all the time in automotive.
Big question is, does Tesla make a profit at that price?
$8K more for 50% more battery. Or $24K for an entire large battery. Big markup there.
