There is no unit sales number in the 10-K that would back-up the astounding Chinese revenues. Actually, I could not find any unit sales number at all in the annual report, and it wasn’t for a lack of trying. The usually quite reliable EV-Sales blog (its author, Jose Pontes, has been portrayed here), says that 7,548 Tesla cars were registered in China in 2016. Last data point is November 2015, when EV-Sales said that 4,125 Tesla cars were registered in China. According to that, Chinese customers would have registered a generous 68% more Tesla cars in 2016 than in the dismal 2015.
