The fifth Tesla Gigafactory worldwide devoted to producing its electric vehicles will be in the U.S. - India.

Construction of the new U.S. manufacturing facility might begin in four to five years but no decision has been made.

Projected demand for Tesla EVs in the U.S., which remains its largest and most lucrative market, was the main reason for Tesla deciding to go with the U.S. A factory in the east will allow for faster deliveries of Tesla EVs to customers there.

In August, Tesla CEO Elon Musk hinted the new gigafactory would most probably be in the northeast. Tesla's two other factories are in the West and in the central part of the country.

Tesla's Fremont, California, factory, which became operational in 2012, makes the Model S, Model X, Model 3 and Model Y. It remains the sole Tesla car factory in the U.S.

The Austin Terafactory, or gigafactory 5, is under construction in Texas.

The $1.1 billion Austin Terafactory will eventually assemble the Tesla Cybertruck electric pickup and the Tesla Model Y CUV starting 2021.

Tesla's intention to build a third U.S. EV manufacturing plant was revealed in documents filed recently with the U.S. Securities and Exchange Commission. An SEC form submitted by Tesla says the planned third factory will produce the Tesla Semi and the Tesla Roadster. It also reveals Tesla's plans are currently "in development."

Hints that the new factory will be located in the U.S. were made in August by Musk. At the time, he said a third production facility in the U.S. was "very likely."

"I think at some point there will be a third Gigafactory. I'd imagine it would be up in the Northeast. There's a mass amount of stuff to do. But, do I think, at some point, we will have a third plant located in North America? I think that's very likely."

There was also speculation Tesla might consider India as the location for its new gigafactory. Musk has, however, promised Tesla will enter the India market "next year for sure."
