What are the methods to distinguish between China V and China VI standards for passenger cars?
2 Answers
The methods to distinguish between China V and China VI standards for passenger cars are: 1. Check the relevant content on the vehicle's compliance certificate; 2. Review the environmental information accompanying the vehicle list; 3. Log in to the Motor Vehicle Environmental Protection Network for inquiry; 4. Verify the national standard number referenced in the vehicle conformity certificate, as the standard number and corresponding year can indicate whether it is China V or China VI. The differences between China V and China VI standards for passenger cars include: 1. Different implementation times: China V standard was implemented in December 2017; China VI standard was implemented in December 2014. 2. Different sulfur content limits: China V standard allows no more than 10mg per kilogram; China VI standard allows no more than 50mg per kilogram. 3. Different PM fine particle limits: China V standard allows 4.5mg per kilometer for particulate matter; China VI standard allows 3mg per kilometer for particulate matter.
I remember when I changed my car last year, I was thinking about how to distinguish between China 5 and China 6 standards. The key is to check the vehicle's environmental label, usually marked as 'China V' or 'China VI' on the nameplate under the hood or the vehicle's certificate. The China 6 standard is much stricter, with significantly lower pollutant emissions—for example, the carbon monoxide limit is reduced by about 30%, which noticeably improves air quality. When buying a car, the salesperson also reminded me to check the production date; vehicles produced after 2020 are mostly China 6 compliant, especially the China 6b version, which can adapt to future stricter traffic restrictions, ensuring no issues in big cities. I usually check the VIN code after getting in the car, using the official website tool for a quick verification to avoid pitfalls. In daily driving, China 6 vehicles have slightly higher fuel consumption but are more environmentally friendly, and regular exhaust emissions tests are also more hassle-free.
