Is National VI the same as China 6?
4 Answers
National VI is China 6, which is the latest phase of China's automotive emission standards. The China 6 standard was released in 2016 and was planned to fully replace the current China 5 standard starting from July 1, 2020. The full name and designation of the China 6 standard is: "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China 6)" (GB18352.6—2016). Here is some relevant information: 1. The China 6 standard is also formulated with reference to the EU emission standards and has introduced a phased implementation plan. The first phase, China 6a, will replace the China 5 standard starting from July 1, 2020; the second phase, China 6b, will replace the China 6a standard starting from July 1, 2023. 2. The China 6 standard was released by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine on December 23, 2016, and June 22, 2018, respectively. The implementation of the China 6 standard will impose stricter requirements on emissions such as carbon monoxide, nitrogen oxides, and hydrocarbons.
When I was researching car purchases recently, I learned that 'Guo VI' is actually another name for the China 6 emission standard. The government started implementing this new standard in 2019 with the aim of reducing vehicle exhaust pollution and improving air quality. Guo VI is divided into two phases: China 6a and China 6b. The former is relatively more lenient, while the latter has stricter requirements, particularly for particulate matter and nitrogen oxide limits. Most new cars on the market now comply with the China 6b standard. When buying a car, you can check the environmental label or the manual for the identification—if it shows 'Guo VI,' it means it's a China 6-compliant vehicle. After optimizing the powertrain, the fuel consumption won't increase much, and it's much more environmentally friendly. As an ordinary driver, I think adhering to this standard is great—it helps us protect the environment and makes urban air cleaner. Don’t forget to check local policies, as some cities restrict older, high-emission vehicles from being driven.
I have extensive experience in automotive maintenance. China VI is the national standard for Stage 6 emission regulations, which has been implemented since 2019. I often encounter vehicle owners asking about this during inspections. It is divided into the China VIa transition period and the China VIb strict phase. A vehicle with the China VI label indicates it has passed the test and meets the new emission standards. The inspection method is simple—just check the label under the hood or the environmental protection certificate; the attached symbol will make it clear. Nowadays, new vehicles are basically equipped with China VI standards by default, reducing PM2.5 generation. During maintenance, be careful not to modify the exhaust system, as it may violate regulations. I believe this standard also benefits the extension of vehicle lifespan by reducing pollution and minimizing mechanical wear.
I care about environmental issues. China VI is indeed the abbreviation for China 6, which is the sixth-stage emission policy introduced by the country. It was announced in 2016 and implemented in phases starting in 2019. It is divided into phases a and b, with the 6b target reducing pollutants in exhaust emissions by 80%, effectively controlling smog and the greenhouse effect. Supporting China VI-compliant vehicles can reduce health risks and promote society's transition to clean energy.
