How to Distinguish Between China 5 and China 6 Vehicles When Buying a Car?
2 Answers
Methods to distinguish between China 5 and China 6 vehicles when buying a car include: 1. Refer to the vehicle's factory certificate; 2. Check the vehicle's environmental standard list; 3. Review the vehicle conformity certificate. The difference between China 5 and China 6 emission standards lies in the carbon monoxide emission levels: China 5 allows 1000mg, while China 6 allows 700mg. China 5, fully named as the National Fifth Stage Motor Vehicle Pollutant Emission Standard, and China 6, the National Sixth Stage Motor Vehicle Pollutant Emission Standard, both regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot emitted from vehicle exhaust.
I did a lot of homework before buying a car, and distinguishing between China 5 and China 6 emission standards isn't actually that difficult. The simplest method is to check the vehicle's Certificate of Conformity or compliance certificate, which directly states the emission standard type. If you're a beginner, you can directly ask the dealer or seller—they'll clearly tell you whether the car meets China 5 or China 6 standards. Another reliable way is to check the door label or VIN code information, as some models display it clearly there. Also, don't forget to look up the vehicle's production date online—most new cars produced after 2019 are at least China 6 compliant, especially in big cities where only China 6 vehicles are allowed for new registrations. Getting this right is super important—otherwise, you might end up buying a China 5 car only to find out you can't register it locally, which would be a hassle. Plus, China 6 emissions are cleaner and more environmentally friendly, so choosing the right one helps reduce air pollution a bit, making it totally worth it.
