In regions where the China VI emission standards have been implemented, the deadline for registering China V vehicles is the date when the local China VI standards take effect. Some areas may have extended grace periods for China V vehicle registration. In regions where China VI standards have not yet been implemented, China V vehicles can still be registered as usual. Below are the differences between China V and China IV standards: Different nitrogen oxide (NOx) emission standards: China IV vehicles have a NOx emission standard of 0.25g/kW. China V vehicles have a NOx emission standard of 0.18g/kW. Different particulate matter (PM) concentration emission standards: China IV vehicles have a PM emission standard of 0.025g/kW. China V vehicles have a PM emission standard of 0.0045g/kW.
