What is the difference between National 4 and National 5 vehicles?
2 Answers
The differences between National 4 and National 5 vehicles are: 1. Different emission standards: National 4 vehicles comply with the National Phase IV Motor Vehicle Pollutant Emission Standards; National 5 vehicles comply with the National Phase V Motor Vehicle Pollutant Emission Standards. 2. Different pollutants emitted: The main pollutants emitted by National 4 vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter; The main pollutants emitted by National 5 vehicles include nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. Methods to determine whether a vehicle is National 4 or National 5: 1. Check the original and duplicate copies of the environmental inspection compliance label; 2. Visit the Motor Vehicle Environmental Protection Website and enter the vehicle model and engine model in the New Vehicle Compliance Query System to check.
As an ordinary person who drives frequently, I feel the biggest difference between National 4 and National 5 vehicles lies in their environmental performance. National 5 vehicles emit lower levels of pollutants, such as nearly halving nitrogen oxide emissions, which contributes significantly more to air quality protection. I remember a few years ago when restrictions were implemented in the city near my home, National 4 vehicles were often restricted in many central urban areas, while National 5 vehicles didn't face this issue. Additionally, National 5 vehicles typically have slightly lower fuel consumption, saving some money on fuel in the long run, and enjoy certain policy advantages, such as easier access to new energy subsidies. However, the new car price for National 5 vehicles might be slightly higher, but from a long-term perspective, investing in environmental protection is still more worthwhile.
