Musk said on the earnings call that "Giga Texas," located east of Austin, is on a similar timeline as the also under-construction "Giga Berlin."
"For Berlin and Austin, we do expect to start delivering cars from those from those factories next year," he said. "Because of the exponential nature of the scaling up of a manufacturing plant, it will start off very slow at first, and the output will become very large."
Within 12-24 months of the factory beginning initial operations, it will operate at full capacity, he estimated.
"That is a very fast period of time, especially for new technology," Musk said.
Construction at Giga Texas began over the summer. Site plans for the project outline a 7.9 million-square-foot manufacturing facility occupying 280 acres on the 2,100-acre property owned by Tesla at the intersection of SH 130 and Harold Green Road in southeast Travis County.
Musk also teased developments with the Cybertruck, which will be produced at Giga Texas.
"We always want to make the car we deliver be better than the car we unveil, and that's the goal with the Cybertruck. There's a lot of small improvements compared to what was unveiled. I think it's going to be better than what we showed," he said. "If all goes well, we'll be able to do some Cybertruck deliveries toward the end of next year, but it's difficult to predict. I would say there's probably a lot of deliveries in 22 and some deliveries toward the end of next year if things go well."
