This is a fascinating insight into the rise of BYD, and how collaboration between the firm and the Chinese government have allowed it to overtake Tesla.

The estimated $30bn in tax exemptions since 2010, with the prospect of more to come means that the company has been a massive beneficiary of this. Equally, the fact that BYD sells 10 models for less than Tesla's cheapest car, gives it access to low-to-middle income consumers - the average BYD car is half the price of the average Tesla as a result of the extent to which the company is vertically integrated and the degree to which is makes its own batteries.

As a result, is it the case that the Chinese have stolen a march in the EV sector.
