Go Inside The Factory Where Robots Build The Tesla Model S

A few months after Tessa Motors turned its first profit, analysts are expecting the electric car company to post a big loss in its Q2 earnings.

One key to Tesla's business is making and selling enough cars to keep itself in business.

In July, CEO Elon Musk said Model S production rate is ahead of schedule, and the company is now rolling out more than 400 new cars each week.

To see how it's hitting that rate, Wired went behind the scenes at Tesla's factory in Fremont, Calif., where it takes three to five days to build a Model S, according to VP of Manufacturing Gilbert Passin.

The process is smooth, efficient, and packed with robots.
