Some of the features include premium audio and radio streaming, navigation, climate control, Bluetooth, internet web browsing etc.

According to VP of Manufacturing Gilbert Passin, it takes three to five days to build Model S.

Tesla Motors plant, how it works?

With such smooth production and supply, a question definitely arises on the production line of the company, how it build its cars, what technology its uses etc.

To answer all these questions, Wired went behind the scenes at Tesla’s factory in Fremont, Calif.

Tesla Motors Inc (NASDAQ:TSLA)’s manufacturing plant is 5.5 million square feet automotive facility packed with robots. As you enter the facility one can see coils of aluminum ready to be carved into sheets that will be used in making panels for the Model S. At the plant, one central facility assembles all the panels, starting with underbody. Then all the panels are glued by a synchronized ballet of robotics. Panel are joined using adhesives, self piercing rivets, cold metal transfer, conventional resistance welding and also using a new delta spot welding system.

After the body of the vehicle is assembled, robots paint the full body within specialized clean rooms. Then the body of Model S is transported to another segment of the plant using automated transport method, which incorporates magnetic strips with floor used as tracks.

Model S from Tesla Motors Inc (NASDAQ:TSLA) may not be a most luxurious or swiftest vehicle around, but its manufacturing plant is definitely state of the art.
