How to Distinguish Between National 5 and National 6 Vehicles?

[Margaret]

Here is an introduction to the methods for distinguishing between National 5 and National 6 vehicles: 1. The relevant numbers in the emission standard column on the vehicle certificate: According to relevant laws and regulations, dealers must provide a certificate of conformity when selling a vehicle, and vehicles without this certificate cannot be registered. On the certificate of conformity, there is a section for the emission standard, which clearly indicates the emission standard number adopted by the vehicle. 'National V' indicates a National 5 model, while 'National VI' indicates a National 6 model. 2. The relevant numbers on the environmental information vehicle list: When purchasing a vehicle, in addition to the certificate of conformity, there will be an environmental information vehicle list in the accompanying documents. In the vehicle information section, there is a column labeled 'emission stage,' which will clearly and directly indicate whether the vehicle is National 5 or National 6. 3. The relevant numbers in the vehicle conformity certificate: When picking up the vehicle, there is another document called the vehicle conformity certificate, which contains many verification items. One of them is labeled 'exhaust emissions,' which directly states the standard number adopted for the 3C certification. 'GB18352.5-2013' refers to the fifth-stage emission standard, i.e., National 5, while 'GB18352.6-2016' refers to the sixth-stage emission standard, i.e., National 6. 4. The numbers queried on the Motor Vehicle Environmental Protection Website: Simply visit the Motor Vehicle Environmental Protection Website, click on the public query platform, and then enter the VIN (vehicle identification number) and the last six digits of the engine number to query the relevant vehicle information, including whether it is a National 5 or National 6 vehicle.
