How to Distinguish Between China IV and China V Standards?
2 Answers
Methods to distinguish between China IV and China V standards are as follows: 1. For vehicles that have already obtained the environmental protection inspection compliance label, the emission standard can be checked on the original or duplicate copy of the label. Alternatively, you can log in to the Motor Vehicle Environmental Protection Website and enter the vehicle model number and engine model in the New Vehicle Compliance Query System. 2. According to the national plan, the China VI emission standard is scheduled to be implemented on July 1, 2020, just three years after the full implementation of the China V standard. In key regions such as the Beijing-Tianjin-Hebei area and its surrounding regions, the Yangtze River Delta, the Fenwei Plain, the Pearl River Delta, and the Chengdu-Chongqing region, the China VI standard will be implemented ahead of schedule. 3. The China VI standard raises the threshold by nearly 50% compared to the current China V standard and is slightly stricter than the current international strictest emission limit—the Euro VI standard. Once officially implemented, the China VI standard will become the world's most stringent motor vehicle emission standard.
I'm often asked by friends how to distinguish between National IV and National V vehicles. As someone who has driven for many years, I think the most straightforward method is to check the vehicle's manufacturing date. Generally, National V standard vehicles started to be gradually promoted after 2013, with nationwide mandatory implementation mostly after 2017, so new cars produced after 2015 are mostly National V. Additionally, you can check the environmental label—the small sticker on the windshield clearly states whether it's National IV or National V. When buying a used car, I always ask the seller to show the registration certificate or purchase invoice, which includes the date and emission standard. The benefit of National V is stricter emissions, such as reducing NOx and CO2 by more than half, leading to better air pollution control. This also helps avoid driving restrictions in some cities—for example, National V vehicles can drive freely in Beijing, making daily commutes smoother. Overall, these details give me more peace of mind when choosing a car and help me avoid unnecessary expenses.
