What is the difference between China National Standard V and VI for vehicles?

[MackenzieFitz]

The difference between China National Standard V and VI lies in the emission standards, with China VI being more stringent. The differences between China V and China VI are as follows: 1. Emission standards: Compared to China V, the China VI standard reduces nitrogen oxides by 77%, particulate matter by 67%, introduces a limit requirement for particle number (PN), and tightens the durability requirements for emission control devices and onboard diagnostic systems (OBD). China VI also proposes stricter compliance supervision requirements, including type inspection and information disclosure, production consistency checks, new vehicle inspections, in-use vehicle compliance checks, and simplifies the compliance determination method. 2. Price: China VI vehicles are equipped with additional components compared to China V vehicles. In addition, automobile manufacturers incur extra costs from various tests for vehicle type approval and production, which results in China VI vehicles being significantly more expensive than China V vehicles.
