What are the differences between China VI and China V vehicles?

[LuciaMarie]

The differences between China V and China VI emission standards are as follows: Different emission standards: China VI emission standards are more than 30% stricter than China V. Excluding the influence of operating conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: China V standards were implemented nationwide on January 1, 2017. China VI standards have been implemented since July 1, 2019. Different principles: In China V, diesel and gasoline vehicles had different emission standards, but China VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: China V standards were issued by the Ministry of Environmental Protection. China VI standards were issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: China V is represented by "V," while China VI is represented by "VI." Different monitoring requirements for plug-in hybrid electric vehicles (PHEVs): Compared to China V, China VI has improved monitoring requirements for PHEVs, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China V standards are as follows: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM (particulate matter) per kilometer driven. China VI has two standards: China VIa and China VIb, as follows: China VIa standards: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM per kilometer driven. China VIb standards: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 mg of PM per kilometer driven. Affected by China VI emission policies, although China V vehicles can still be used normally without travel or license plate restrictions, their resale value will be significantly impacted. For truck owners, if they purchase a truck on loan for cargo transport, the depreciation of the vehicle after repaying the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China VI vehicles, which have a longer service life and more road rights, are more advantageous.
