I think Model Y will use a rear casting, my question is how fast IDRA can build new casting machines and the priorities which determine how machines are used, Also any redesign of Model 3 for castings and 4680 batteries, might need significant engineering resources.I would find it odd for Tesla to build a new assembly line for the Model 3/ Y and not use Gigacastings.
Previously I did think Berlin might do a Model 3 with front/rear castings and a 4680 structural battery. Which could still happen.
I'm reflecting in part on the Model S/X refresh which continued to use 18650 batteries and made minimal changes to the body design.
As it stands Model 3 might be good enough for now, and the priority might be to design new models.
Also perhaps the new facility is for Model Y only and existing lines in the factory which can build 3 and Y will build more Model 3s
Otherwise you are right, more body shop robots would be needed if castings were not used.
