Tesla would then plan to have around a 1 million car per year production rate in 2020.
Reaching the 2020 target of a million cars per year would make Tesla Motors about the 20th largest car maker by production volume.
In 2015, BMW had a production volume of about 2.25 million.
In 2020, Tesla would be nearing the production volume of Mazda and Mitsubishi.
