How to Distinguish Between China 5 and China 6 Standards?

China 5 and China 6 standards can be distinguished by: 1. Checking the vehicle's factory certificate; 2. Referring to the vehicle's environmental standard list; 3. Reviewing 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, officially known 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 permissible levels of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot emitted from vehicle exhaust.

I've been in car repair for many years, and from the perspective of emission standards, the difference between China 5 and China 6 is quite significant. China 5 was the standard from a few years ago with relatively lenient limits. For example, the nitrogen oxide emissions under China 6 are much stricter, almost half of China 5's; the testing methods are also different—China 6 uses the WLTC cycle to simulate real driving conditions, unlike the more idealized NEDC used for China 5. Additionally, the vehicle monitoring system requirements under China 6 are stricter, with OBD capable of real-time monitoring of emission anomalies. When buying a car, I recommend prioritizing China 6 because many cities like Beijing and Shanghai now restrict China 5 vehicles from being registered. China 6 vehicles can also save some fuel costs and are more environmentally friendly. Regular maintenance can also extend the car's lifespan and prevent obsolescence due to outdated standards.

As a frequent driver, I often get confused between China 5 and China 6 when choosing a car. The China 6 emission standard is cleaner with less pollution, and its fuel consumption is slightly lower than China 5, saving some money in the long run. Cities have stricter restrictions, and China 5 vehicles cannot be registered in some areas, while China 6 doesn't have this issue. Just check the vehicle's environmental protection list for G5 or G6 codes. Before buying, I compare several models, and China 6 vehicles have faster power response but are slightly more expensive. It's best to consult a professional shop to avoid buying old stock. Now, the policy promotes the stricter China 6b standard, making travel more reassuring.

I care about environmental protection, the core difference between China VI and China V lies in air protection; China VI has stricter limits, reducing particulate emissions and decreasing smog; the tests are more realistic, with stronger pollution control during actual driving; choosing China VI vehicles can help improve urban air quality; the promotion significance is great, encouraging everyone to upgrade. A simple way to distinguish is to look at the new vehicle emission label.
