Tesla's main factory is located in the East Bay town of Fremont, in northern California.
Tesla bought the plant from Toyota in 2010. In the 1980s, it was operated as a joint venture between Toyota and GM and called "New United Motor Manufacturing, Inc." or NUMMI.
Tesla still maintains NUMMI's old test track, which features a pair of banked loops.

But the most notable factory in the world is perhaps Ferrari's complex in Maranello, Italy.
