What Do China V and China VI Vehicles Mean?
2 Answers
China V and China VI vehicles refer to the automotive emission standards, which regulate the content of harmful gases such as carbon monoxide, nitrogen oxides, and particulate matter emitted from vehicle exhaust. The China V standard sets the nitrogen oxide emission limit at 0.18 grams per kilometer, particulate matter concentration at 0.0045 grams per kilometer, and non-methane hydrocarbon emissions at 0.23 grams per kilometer. The China VI standard reduces the nitrogen oxide emission limit to 0.16 grams per kilometer, particulate matter concentration to 0.022 grams per kilometer, and non-methane hydrocarbon emissions to 0.18 grams per kilometer.
I did quite a bit of research on China 5 and China 6 emission standards when I changed my car. Simply put, these are national vehicle emission standards - the higher the number, the stricter the requirements. China 5 is the fifth-phase standard implemented nationwide in 2017, while China 6 is the sixth-phase standard introduced in two stages (a and b) starting from 2019. The main differences lie in exhaust emission limits - China 6's nitrogen oxide limits are over 40% lower than China 5's, plus it added real-world driving emission testing. I personally chose a China 6 compliant car. Although it cost a few thousand yuan more, I considered better resale value in the future. Many major cities have already started restricting China 4 and China 5 vehicles, so I was concerned about potential driving restrictions if I bought a China 5 car. However, China 6 vehicles are more particular about fuel quality and require gasoline from certified gas stations.
