What is the difference between China 5 and China 6 vehicles?
1 Answers
The differences between China 5 and China 6 emission standards are as follows: Different emission standards: China 6 emission standards are more than 30% stricter than China 5. Excluding the influence of working conditions and testing, gasoline vehicles reduce carbon monoxide emissions by 50%, total hydrocarbons and non-methane hydrocarbons by 50%, and nitrogen oxide emissions by 42%. Different implementation times: The China 5 standard was implemented nationwide on January 1, 2017. China 6 has been implemented since July 1, 2019. Different principles: In the China 5 stage, diesel and gasoline vehicles had different emission standards, but China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: The China 5 standard was issued by the Ministry of Environmental Protection, while the China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. Different letter representations: China 5 is represented by "V," while China 6 is represented by "VI." Different monitoring requirements for plug-in hybrid vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. They must not emit more than 68 mg of non-methane hydrocarbons, 60 mg of nitrogen oxides, or 4.5 mg of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b. Their limits are as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. They must not emit more than 68 mg of non-methane hydrocarbons, 60 mg of nitrogen oxides, or 4.5 mg of PM per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. They must not emit more than 35 mg of non-methane hydrocarbons, 35 mg of nitrogen oxides, or 3 mg of PM per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles can still be used normally without restrictions on driving or licensing, their resale value will be significantly impacted. For car owners, if they purchase a truck for freight transport on loan, 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 6 vehicles, with longer service life and more road privileges, have greater advantages.
