Tesla delivers first China-made cars from $5bn Shanghai factory | Technology | The Guardian

First 15 Model 3 electric cars go to employees and US firm will ramp up production in 2020

Tesla has delivered the first vehicles it has made in China, marking a major milestone in the electric car maker’s global expansion efforts. The first 15 Model 3 cars to roll off the line at the US car maker’s Shanghai factory went to customers who were Tesla employees and were handed over in a ceremony at the plant on Monday.

Tesla will ramp up production during January, marking the start of a full-on assault on the world’s largest car market. It has taken less than a year from the start of construction of the $5bn (£3.8bn) Shanghai factory in January to the delivery of the first vehicles.

I don't know when Tesla sleeps but he does crank out the production.
