How to Distinguish Whether a Car is China 6 Compliant?

[OwenLynn]

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 driving 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: The China 5 standard was implemented nationwide on January 1, 2017, as the fifth stage of national motor vehicle emission standards. China 6 was implemented starting July 1, 2019. Different principles: Under China 5, 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. 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 electric vehicles: Compared to China 5, China 6 improves monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulatory aspects. China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b, as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles can still be used normally without restrictions like traffic bans or license plate limitations, their resale value will be significantly impacted. For car owners, if they purchase a truck for freight transport with a loan, the vehicle's depreciation 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, which have a longer lifespan and more road rights, are more advantageous.

To determine if a car meets China 6 standards, which is a top priority for family-oriented car owners like me, focus on the environmental information label. This label is usually affixed to the windshield or door and clearly states "China 6" if compliant. For new cars, check the sales contract and invoice for the standard specification—don’t rush to sign; verify carefully. With used cars, extra caution is needed: inspect the environmental section of the vehicle registration certificate, the official record. Cars manufactured after mid-2019 are generally China 6b compliant. Bringing a car-savvy friend along can help avoid purchasing a falsely labeled vehicle. Additionally, the DMV system can instantly confirm compliance during registration—a hassle-free and reliable method. During routine maintenance, ask technicians; their emissions system checks can provide supplementary confirmation. Remember, China 6-compliant cars are better for air quality and offer peace of mind while driving.

To distinguish China 6 vehicles, focus on several key points: first, check the emission standard label on the vehicle nameplate; second, refer to the environmental protection vehicle accompanying documents; third, look for the 'China 6' mark on the new vehicle's factory certificate. For used cars, check the registration certificate. Additionally, most new vehicles manufactured after 2020 comply with the China 6b standard. The VIN can also be used to verify the standard on the official website.

With 20 years of driving experience, I can tell you that identifying China 6 standards doesn't need to be complicated. Just check the environmental information card in the vehicle documentation package - the standard is clearly stated there. If you can't find the nameplate under the hood, refer to the duplicate of the conformity certificate. For new cars, salespeople will proactively provide the standard certification. When buying used cars, always check the environmental section in the green registration book - China 6 vehicles will have clear markings. Note that China 6 has two phases: a and b, with b being more stringent. Before purchasing, it's safest to visit the vehicle management office for consultation to avoid fines or registration issues.

Confirming that a vehicle meets China VI standards is beneficial for environmental protection, speaking from the perspective of air quality concern. You can check the emission status by entering the VIN code on the official website or app. The nameplate and environmental label clearly display the China VI logo. The new vehicle certificate must indicate the standard. During daily use, emission data can be verified through the OBD interface. China VI vehicles have excellent emission reduction effects, so prioritize selecting such vehicles when purchasing.
