In regions where China VI has not been implemented, China V vehicles can be registered. However, in areas where China VI has already been implemented, China V vehicles cannot be registered. The emission control level of the China V standard is equivalent to the fifth-stage emission standard currently implemented in Europe. Compared to the China IV standard, the sulfur content in China V standard gasoline is reduced by 80%. Differences Between China V and China VI: The China VI emission standard requires lower carbon monoxide content in vehicle exhaust, lower non-methane hydrocarbon content, lower nitrogen oxide content, and lower PM (particulate matter) content. Compared to the China V standard, the China VI standard is more stringent. Implementation Timeline of China VI: The implementation of the China VI emission standard will be divided into two phases. Starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the China VI standard 'a' limit requirements. The second phase will begin on July 1, 2023, when all light-duty vehicles sold and registered must comply with the China VI standard 'b' limit requirements.
