What are the differences between China 5 and China 6 vehicle standards?
2 Answers
The differences between China 5 and China 6 vehicle standards lie in price variations and access restrictions. Specific details are as follows: Price variations: China 6 vehicles are more expensive than China 5 vehicles, primarily because China 6 vehicles are equipped with additional configurations to comply with policy requirements. Automakers also need to submit applications to relevant authorities and conduct various pollution tests, which increases costs and consequently raises the vehicle prices. Differences in access restrictions: With the implementation of China 6 standards, vehicles that do not meet the emission standards will face certain restrictions during operation. China 5 and below vehicles will be directly prohibited from road use due to non-compliance with emission requirements.
I just helped a friend choose a car a couple of days ago and happened to research China 5 and China 6 emission standards. Simply put, China 6 has much stricter exhaust requirements. For example, the CO emission limit is 30% lower than China 5, and particulate matter is also more strictly regulated. The testing methods are more realistic, checking emissions during high-speed driving. Vehicles must be equipped with OBD systems to monitor exhaust in real time, and the dashboard will light up if standards are exceeded. China 6 is further divided into two phases, a and b, and most new cars now meet China 6b. When buying used cars, pay special attention to emission standards—in major cities like Beijing, Shanghai, Guangzhou, and Shenzhen, China 5 vehicles might face relocation restrictions and could be ineligible for license plates.
