China National V emission standard vehicles first started production in 2012. 1. National V is an emission standard, which is stricter than National IV: it requires fewer pollutants to be emitted, making it more environmentally friendly. From the vehicle's perspective, it mainly involves more complex emission control systems and increased costs.
