BYD Auto Business In 2003, BYD entered the automotive business by purchasing the Tsinchuan Automobile Company Limited (now BYD Auto Company Limited) and started to develop national own brand automobiles. Its automotive products include auto moulds and parts, high-end, medium-end and low-end fuel vehicles, dual mode electric cars and pure electric cars. Among these are traditional high quality fuel vehicles like the F3, F3R, F6, F0, S8, G3, M6, L3, G3R, S6, Song, Yuan and so on. BYD follows the Unique, Superior, Proactive and Leading approach in the NEV field. In 2015, BYD initiated its 7+4 Full Market EV Strategy , a strategy that aims to replace all fossil fuel consumption in the road transport field with electricity. From the initial new energy consumer vehicles, buses, taxis and forklifts, to the NEVs for such fields as road passenger transportation, coach, logistics vehicle, construction vehicle and sanitation vehicle, BYD keeps moving forward steadily. In 2017, BYD NEVs will further penetrate into the specialized fields of airports, ports, warehouse and mining, significantly enlarging its NEV footprint.
