Chinese carmaker: Chinese carmaker BYD overtakes Tesla as world's most popular EV maker

The automaker is poised to surpass Tesla Inc. as the new worldwide leader in fully electric vehicle sales. When it does — likely in the current quarter — it will be both a symbolic turning point for the EV market and further confirmation of China’s growing clout in the global automotive industry.
