Tesla has revolutionized manufacturing with innovations like the Giga Press. "Gigafactories" are large-scale manufacturing facilities that use advanced automation and robotics. These factories are more efficient and cost less than traditional manufacturing methods.
The Model 2 will incorporate everything they have learned. Compare that to legacy major car manufacturing that have aging, scattered factories running old software for procurement and operations. Highly labor intensive. It's a logistics nightmare. Did you know the Fremont plant (ex-GM and ex-NUMMI) is the most productive auto plant in America?
According to Musk, the Model 2 will be built in the US at Tesla's Gigafactory in Texas, where the Cybertruck is assembled. The Gigafactory Mexico, which was initially rumored to be the first production site for the Model 2, will be ready after the car's launch, Musk said.
Time will tell how the Model 2 turns out. The Monterrey location was chosen in large part because of its proximity to Austin, and because of a large, educated work force.
