What are the differences between China VI and China V?

[OJasper]

China VI and China V mainly have the following differences: 1. The biggest difference between China V and China VI vehicle emission standards is the stricter control of pollutants. 2. The China V emission standard is the national fifth-stage motor vehicle pollutant emission standard. According to the China V vehicle emission standard, it reduces nitrogen oxide and particulate emissions by 25% and 80% respectively, controlling vehicle pollution to some extent. 3. After the implementation of the China VI standard, vehicle exhaust emissions will be reduced by more than 50% compared to the China V emission standard, with the primary purpose of reducing the pollution of exhaust emissions on the atmospheric environment.

From an environmental perspective, China 6 and China 5 are both vehicle emission standards, with China 6 being significantly stricter than China 5, mainly in terms of pollutant limits. For example, China 6 reduces nitrogen oxide emissions by nearly half compared to China 5, and particulate matter is also substantially reduced, directly decreasing air pollution from exhaust. Having driven for over a decade, I've seen the phased implementation of China 6 starting in 2019. Nowadays, most new cars are China 6 compliant, while older China 5 cars depreciate quickly in the used car market due to traffic restrictions in some cities. In the long run, China 6 vehicles are more environmentally friendly, benefiting urban air quality and helping people inhale less exhaust. Although China 6 models are more expensive initially, they are more responsible for the environment and society in the long term, making this change worth supporting.

As an average car owner, I compared National V and National VI standards when changing cars. National VI vehicles are usually priced slightly higher, possibly by a few thousand yuan, but offer better fuel efficiency due to optimized engine performance. There's little difference in daily maintenance, but National VI's OBD system is more intelligent, enabling real-time emission monitoring to avoid fines. Policy-wise, National VI has clear advantages in major cities like Beijing and Shanghai with fewer traffic restrictions. National V used cars are cheaper but may face future limitations. I believe National VI is worth the extra cost for safer driving.

From a technical perspective, China VI upgraded exhaust treatment systems like particulate filters to reduce black smoke emissions. It imposes stricter requirements than China V with more realistic testing standards such as the WLTP method. Maintenance changes are minimal but parts are slightly more expensive.

From an economic perspective, the China 6 emission standard vehicles hold their value better, especially in major cities due to policy support. China 5 vehicles depreciate quickly with more subsidies for new cars. Traffic restrictions affect daily commuting, making China 6 vehicles more convenient.

In daily use, the driving experience of China 5 and China 6 standards is similar, with smooth acceleration, but China 6 has lighter exhaust odor, making it more pedestrian-friendly. With fewer policy restrictions and strong practicality, I think choosing China 6 is better for future compatibility.
