So, as of November 2015, Tesla lost almost $20,000 per car that they sold. According to this article below, it is an increase of $4,000 per car since the previous quarter! This is partially due to the poor economies of scale in the mass-production of electric cars. Musk wants you to believe that he is an upcoming competitor to the Big 3 - except while he sells around 50,000 cars a year, GM is selling 9 million. So yeah, Musk wants to increase the production capacity at his car and battery-making plants. Hence, the Model 3 hype campaign, which, really, at this stage is based on promise and hype to raise the necessary capital. It doesn't mean that he can actually make money at it, or that he will even come through with the orders. Tesla has always come short on production promises.

How is Musk able to keep losing so much money on a technology that is so obviously inefficient, and still keep the lights on his factories? He sells emissions credits to the California government. Taxpayers indirectly subsidize every cent of that $20,000 loss.
