Model S/X packs are assembled at Fremont, and are never processed through GF1.
To workaround tariffs for S/X, a model that is similar to Tillsburg (Europe) , could be set up ...
Right now it is S/X sales that are suffering from the 55% tariffs
Edit(Add)..For Model 3, might as well start simplified production line (the one under tent) .. that took 2-3 months to setup. For this as well, until stamping press etc are all in place, send the parts over from Fremont & Sparks
(production line with Kuka robots might we easier to set up ) .. than the rest of the parts ... ~ cheers
