Tesla Motors’ first mass-market car, the Model 3, will begin rolling off the line on Friday, two weeks earlier than planned, Elon Musk, the company’s chief executive, said late Sunday.
Mr. Musk said on Twitter that production would increase quickly, with 100 Model 3s produced in August and 1,500 or more in September. He said that he expected the company to be able to produce 20,000 per month beginning in December.
The Model 3 is a critical test for Mr. Musk and his ambitious plan to turn Tesla into a producer of mass-market electric cars.
