What is the China VI Vehicle Standard?

[DeAndrew]

China VI standard, officially known as the National Sixth Stage Emission Standards for Motor Vehicles, refers to the standards formulated to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China, aiming to prevent environmental pollution caused by exhaust emissions from compression ignition and gas fuel ignition engine vehicles, protect the ecological environment, and safeguard human health. The implementation of the China VI emission standard is divided into two specific phases: 1. Phase One: Starting from July 1, 2020, all sold and registered vehicles must comply with the China VI A standard. 2. Phase Two: Starting from July 1, 2023, all sold and registered vehicles must comply with the China VI B standard; some cities will implement the China VI light-duty vehicle emission standard ahead of schedule.

The China VI vehicle standard refers to the sixth-stage national motor vehicle emission standard in China, which sets stricter exhaust emission rules to reduce air pollution. I remember seeing in the news that it was fully implemented starting in 2020, with a phased transition divided into China VIa and China VIb. Simply put, this requires newly manufactured vehicles to significantly reduce emissions of pollutants such as carbon monoxide, nitrogen oxides, and particulate matter, making it much stricter than the previous China V standard. This benefits ordinary people greatly, especially in large cities, as it improves air quality and reduces the risks of smog and respiratory diseases. I often remind friends to pay attention to this standard when buying a car, because China VI vehicles are more environmentally friendly and can retain their value for longer. Although electric vehicles are developing rapidly, the China VI standard also drives technological advancements in gasoline vehicles, such as adding particulate filters and catalytic converters, helping to achieve carbon neutrality goals and making transportation greener overall.

As an average car owner who just upgraded to a China 6 compliant vehicle last year, the salesperson explained that this standard aims to make exhaust emissions cleaner and more environmentally friendly. Specifically, it requires new vehicles to pass stricter tests during production, such as reducing nitrogen oxide emissions to extremely low levels—even more stringent than European standards. Opting for a China 6 compliant car offers numerous benefits: while the initial price might be higher, it saves money on maintenance, is eco-friendly, and helps avoid urban driving restrictions in some cities. My personal experience with a China 6A phase vehicle shows significantly reduced exhaust odor and lower noise levels in city driving. Additionally, it's worth noting that China 6B phase imposes even stricter requirements, potentially accelerating depreciation of older vehicles in the used car market. In short, always check for the environmental label confirming China 6 compliance when purchasing—it’s a long-term investment in both health and the environment.

The China 6 standard is the sixth-stage emission regulation for new vehicles in China, aiming to reduce harmful gas emissions and pollution. To put it plainly, since 2019, new vehicles must pass rigorous tests before leaving the factory, such as Real Driving Emissions (RDE) tests, to measure whether PM and NOx levels in the exhaust meet the standards. Compared to China 5, it imposes stricter limits, forcing automakers to adopt more advanced engine technologies, such as installing high-efficiency filters. This standard is divided into two tiers, A and B, with Tier B having higher requirements, which can significantly improve the environment but may slightly increase costs. In the long run, it drives the industry toward cleaner development.
