One-half of a million electric cars would be quite an achievement
The production will be mostly at Tesla's factory in Fremont, California, but by that time a small mount production of the Tesla Model 3 could start in China too.
In 2018, Tesla produced 254,530 cars, which was 152% more than in 2017.
"Tesla made 0 cars in 2011, but will make around 500k in 2019"
"Meant to say annualized production rate at end of 2019 probably around 500k, ie 10k cars/week. Deliveries for year still estimated to be about 400k."
Deliveries in 2018 amounted to 245,506 (up 138%), so an increase to 400,000 would translate to about 63% growth, year-over-year.
We guess that Tesla is already able to produce roughly 8,000 cars per week (S, X and 3), which is not too far off from the 10,000 weekly target required to hit 500,000.
