What are the differences between National 5 and National 6 vehicle emission standards?

[PaigeRose]

Here are the differences between National 5 and National 6 vehicle emission standards: 1. Price difference: National 6 vehicles are more expensive than National 5 vehicles, mainly because National 6 vehicles need to comply with policy requirements by adding more configurations. Automakers also need to submit applications to relevant departments and undergo various pollution tests, which increases costs and leads to higher vehicle prices. 2. Access restrictions: With the implementation of National 6 standards, vehicles that do not meet the emission standards will face certain driving restrictions. National 5 and below vehicles may be directly prohibited from road use due to non-compliance with emission requirements.
