This must surely back up the notion that the car continues to use 18650, and hasn't graduated up to something newer.
(Yes there have been some pretty authoritative statements on the matter already)
It amazes me to think about the improvements that loom on the horizon for Model S/X - when its performance is now so incredible:
* front casting piece
* rear casting piece
* switch to 4680 cells
* structured pack
These improvements will all allow Tesla to "dial in" the exact performance improvements they want - acceleration, range, and profitability. Tesla might upgrade the range of the car a bit more, keep the acceleration the same, but make the car lighter, for better handling+range again, and a cheaper cost of construction. Will we see a reduction in retail price or just take more profit per vehicle? It's Tesla's choice... and possible they will add FSD as standard and keep the base price of the car the same at $79,900.
(While I'm here... it's my opinion that FSD will become standard on all Tesla vehicles at some point)
