Chinese automobile company Chongqing Changan said it would stop selling combustion-engine cars in 2025 and would instead invest some 100 billion yuan ($15.1 billion) to advance a new energy strategy , Reuters reported Oct. 19. Chongqing Changan is among the first Chinese companies to completely shift away from petrol-engine cars to less polluting technologies. In an effort to combat air pollution, China set a goal to have electric and plug-in hybrid cars comprise a fifth of auto sales by 2025.
