Really good update from Austin by
Joe Tegtmeyer
Assembling the fourth casting machine, it looks like they can fit another 8 in after that. Each pair of stamping machines have capacity for 250,000 vehicles, so total capacity would be 2.5 million.
Also adding a new stamping machine and building the foundations for another one.
It looks like there are at least 3 lines of cell production installed
Three Model Y in final assembly (or perhaps complete after assembly).
More installation occuring all over the building.
