What is the China VI Standard?
2 Answers
China VI is the China 6 standard. The following is an introduction to China 6 vehicles: China VI: Full name: National Sixth Stage Emission Standards for Motor Vehicle Pollutants, which refers to the emission standards for vehicle exhaust. Currently, China is implementing the China 5 emission standard; the China 6 emission standard is 40%-50% stricter than China 5, comparable to U.S. standards, and can be considered one of the most stringent emission standards globally. The China 6 emission standard is implemented in two phases: China 6a and China 6b, with China 6b being stricter than China 6a. Implementation Requirements for China VI: According to national requirements, the China 6 standard is implemented in two phases. Starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the "China 6a" limit requirements; from July 1, 2023, all light-duty vehicles sold and registered must comply with the "China 6b" limit requirements.
After driving for over a decade, I finally grasped the China VI emission standard. It mandates cleaner vehicle emissions by strictly limiting pollutants like carbon monoxide, hydrocarbons, and particulate matter. Compared to the previous China V standard, it imposes significantly stricter exhaust pipe emission limits—approximately 30% lower. Nowadays, 4S dealerships strongly recommend China VI-compliant models since non-compliant vehicles can't be registered in urban areas. Mechanics emphasize using genuine filters during maintenance to avoid malfunctions. Environmentally beneficial, it noticeably improves urban air quality with fewer hazy days. Long-term, it pushes automakers to develop high-efficiency engines but accelerates older vehicle phase-outs, potentially impacting used car values. Remember its nationwide rollout in 2019, implemented in phases across provinces.
