Tesla Motors’ bustling Fremont factory could roughly double in size under a long-range plan filed with city officials, as the automaker seeks to dramatically expand production of its luxury electric cars.

As reported by the sfchronicle.com the new buildings could be added near the plant’s paint shop. Formerly run by a joint venture between General Motors and Toyota, the plant now employs 6,200 people building Tesla’s popular Model S sedan and Model X SUV. And with Tesla Model 3, late next year, the company needs room to expand.


Tesla has set a goal of building 1 million cars per year by the end of 2020, even though the company last year built just 50,500. And Musk said this spring that Tesla might be able to reach its million-car goal by fully utilizing its Fremont factory, its massive battery Gigafactory near Reno and a collection of other properties Tesla has amassed in Northern California.

After receiving around 400,000 reservations for the Model 3 earlier this year, Tesla announced its plans to achieve a production rate of 500,000 cars per year at the factory by 2018. That’s close to the same output that the plant had when it was being operated by Toyota and GM.

While Musk said that Tesla’s overall production could increase to 1 million vehicles by 2020 and while it’s not clear if all vehicles will be produced at the Fremont factory, he did say that he sees a path to the plant allowing for a total output of 1 million cars.
