What are China 6 and China 5 vehicles?
2 Answers
China 6 vehicles refer to cars that comply with the National Sixth Stage Emission Standards for motor vehicle pollutants, while China 5 vehicles refer to those that meet the National Fifth Stage Emission Standards. Below are the differences between China 5 and China 6 emission standards: 1. Different emission standards: China 6 standards are more than 30% stricter than China 5. Under the same driving conditions and test influences, gasoline vehicles under China 6 reduce carbon monoxide emissions by 50%, total hydrocarbons and non-methane hydrocarbons by 50%, and nitrogen oxide emissions by 42%. Additionally, China 6 standards introduce new regulations for PN (particulate number) particle emissions. 2. China 6 standards enhance monitoring requirements for plug-in hybrid electric vehicles. These requirements cover eight aspects: energy storage systems, thermal management systems, brake regeneration, drive motors, generators, plug-in EES (electrical energy storage), other input or output modules, and exemption requirements for certain plug-in components.
China V and China VI refer to the standard levels of vehicle exhaust emissions, just like different passing grades for students in different grades. China VI is currently the most stringent emission standard, implemented nationwide since 2020. It is much stricter than China V, especially with 40%-50% lower nitrogen oxide and particulate matter emissions. Most new cars you buy now are China VI b, as the nationwide upgrade occurred three years ago. When purchasing a car, check the phase number on the environmental label to understand, and annual inspections also test exhaust emissions according to this standard. China V vehicles face restrictions on relocation in some cities, and their resale prices are also affected. It is recommended to pay special attention to the registered emission level in your vehicle's information section.
