Super cool look behind the scenes at the Tesla factory by National Geographic Megafactories in 2012 before the Model S began production.

The episode includes interviews with Elon Musk, JB Strauble, Franz Von Holzhausen, and Gilbert Passin (while he’s riding a bike around the factory). It also looks at the design studio in L.A., showcases how the assembly line robots are programmed, and drills down into most aspects of the Model S.
