What is the difference between the Tuyue National 5 and National 6 models?

[VonAlan]

The difference between the Tuyue National 5 and National 6 models lies in their exhaust emission systems: the Tuyue National 5 has higher exhaust emissions, while the Tuyue National 6 has lower exhaust emissions. Below is relevant information about emission standards: 1. China's National 6 vehicle emission standards are divided into National 6a and National 6b standards. The National 6a standard was officially implemented on July 1, 2020, and the National 6b standard was officially implemented on July 1, 2023. The National 6 vehicle emission standards are the strictest vehicle emission standards in China's history. 2. After the implementation of the National 6 standards, vehicle exhaust emissions will be reduced by more than 50% compared to the National 5 emission standards. Carbon monoxide, hydrocarbons, and non-methane total hydrocarbon emissions will decrease by 50%, and nitrogen oxide emissions will decrease by 42%. Overall, the National 6 vehicle emission standards are more stringent.
