Is VI China 5 or China 6?
2 Answers
China VI refers to the China 6 emission standard. In the China 6 emission standard, it is divided into two emission standards: China 6a and China 6b. Definition of China 6 Standard: The National Sixth Stage Emission Standard for Motor Vehicle Pollutants is 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," to prevent pollution from exhaust emissions of compression-ignition and gas-fueled ignition engine vehicles, protect the ecological environment, and safeguard human health. Composition of China 6 Standard: It includes two parts: "Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China 6)" and "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China 6)."
As a long-time car owner, I've personally experienced the transition from China 5 to China 6 emission standards, where VI typically represents China 6. My old car was China 5 compliant, purchased before 2017, with relatively lenient exhaust emission requirements. Last year, I upgraded to a China 6 vehicle, which is noticeably more fuel-efficient and produces less air pollution. The China 6 (VI) standard imposes stricter limits – for example, CO emissions are reduced by half compared to China 5, with additional particulate matter testing especially for diesel vehicles. While daily driving feels similar, the environmental benefits are significant. If you're unsure about your vehicle's standard, the simplest method is to check the engine compartment label or the certification mark on your vehicle documents – look for 'C6' or 'VI' to identify China 6 compliance. New cars now universally meet China 6 standards, while older models might still be China 5, which could affect registration policies.
