How to distinguish between China V and China VI vehicle emission standards?

[McDante]

The methods to distinguish between China V and China VI vehicle emission standards: 1. Check the vehicle conformity certificate, environmental protection information accompanying vehicle list, or vehicle qualification certificate, which will clearly record the vehicle's emission standard; 2. For new cars, the salesperson will provide a vehicle acceptance form containing information such as model, color, emission standard, engine number, and chassis number. For used cars, the complete vehicle model can be checked on environmental protection websites; 3. Usually there is an identification plate below the co-pilot's door. Relevant labels showing the complete vehicle model may also be found in places like the lower left corner of the windshield, driver's door pillar, left side of the instrument panel, engine compartment, door stickers, door frame base, or glove compartment.
