Which is China V, v or vi?

v is China V. China V and China VI refer to emission standards, where higher numbers are better, indicating greater environmental friendliness. Specific details are as follows: 1. The difference between China V and China VI: The difference lies in China VI using a better three-way catalytic converter, making its emission standards stricter than China V, resulting in lower pollution levels from engine exhaust. The maximum sulfur content in China V standard gasoline is 10mg/kg, while for China VI standard, it is 50mg/kg. 2. The difference between China V and China VI for vehicles: The distinction is in the emission standards, with China VI standard gasoline having a maximum sulfur content of 50mg/kg, compared to 10mg/kg for China V.
When I previously researched automotive emission standards, I found that V and VI represent the classification of European emission standards, which correspond to China's national standards in the domestic market. V refers to Euro V, which is directly equivalent to our National Standard V (Guo Wu). It was the mainstream configuration a few years ago—for example, my old car is Guo Wu, which is fuel-efficient but has slightly looser environmental limits. VI corresponds to Euro VI, the newly introduced National Standard VI (Guo Liu), which imposes stricter carbon emission requirements. Many new cars now adopt this standard. When buying a car, it's important to pay attention to this indicator because it affects traffic restrictions. For instance, in my city, Guo V vehicles sometimes face road restrictions, while Guo Liu cars have smoother access. I recommend checking the vehicle manual or environmental compliance list to confirm and avoid purchasing a non-compliant car that could impact daily commuting.
From a technical perspective, I have experience with automotive emission standards. The difference between V and VI lies in the numerical level: V represents the Euro V standard, equivalent to China's National V, with higher emission control parameter limits such as nitrogen oxides. VI upgrades to Euro VI, i.e., National VI, which has much stricter standards, especially with fewer particulate emissions. In my daily repair work, I've seen many cases where National V vehicles have lower maintenance costs, but National VI is more environmentally friendly and quieter. When choosing, it's essential to consider local regulations—for example, tier-one cities have already prioritized implementing National VI, so VI (National VI) is more cost-effective in the long run. I recommend checking the vehicle registration details with the DMV or consulting a professional to avoid misunderstandings.
