What is the China VI standard equivalent to?
2 Answers
China VI represents the China 6 emission standard, which mainly refers to the vehicle exhaust emission standards. China began implementing the China 6 emission standard on July 1, 2019. The China 6 emission standard increases the exhaust emission requirements by 50% compared to the China 5 standard. Here is an introduction to the China 6 emission standard: 1. The China 6 emission standard is divided into China 6a and China 6b. According to national regulations, starting from July 1, 2020, all light-duty vehicles sold and registered must meet the China 6a limit requirements. From July 1, 2023, all light-duty vehicles sold and registered must comply with the China 6b limit requirements. 2. The China 6 emission standard is more in line with China's actual national conditions. The carbon monoxide content in the China 6b standard is reduced by half compared to the China 5 standard, and the carbon oxide content standard is also reduced by about half. The early implementation of the China 6 standard is also very helpful for environmental improvement.
I specialize in automotive emissions research. The China VI standard is actually the sixth phase of the National Vehicle Emission Standards, which has been gradually implemented since 2019 with extensive coverage, applying to most cities nationwide. Its core objective is to establish strict upper limits for tailpipe emissions—for instance, nitrogen oxides and particulate matter emissions are reduced by nearly 40% compared to China V, significantly improving air quality. This not only impacts new vehicle manufacturing, requiring automakers to upgrade technologies such as adopting more efficient catalysts and particulate filters, but also affects daily vehicle use—China VI-compliant cars require higher-grade gasoline to avoid DPF clogging issues. In the long run, as the new standard becomes widespread, the resale value of China V vehicles will decline. It is recommended that car owners prioritize China VI-compliant models to ensure environmental compliance and hassle-free mobility.
