BYD built its six millionth new energy vehicle (NEV) at its Zhengzhou factory today (Friday 24 November).
The Chinese term NEV encompasses hybrid, plug-in hybrid and BEV models.
BYD built its five millionth NEV just three months ago.
The nominated milestone six millionth NEV was a BAO 5 hybrid SUV from the Fangchengbao sub brand.
BYD also said it had set an October monthly sales record, selling 300,000 NEVs.
The automaker has adopted a dual approach of exports and local production to "accelerate the global presence of new energy passenger vehicles".
It now sells in 58 countries and regions, notably in Thailand where it plans a RHD factory, and Brazil.
