What does Guo V1 mean?

In fact, it is not "Guo V1" but "Guo VI". "Guo VI" refers to China 6, which stands for the "National Sixth Stage Emission Standards for Motor Vehicles". It includes "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)" and "Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)". Details of the China 6 standard: The China 6 standard references both the Euro 6c standard for emission limits and the OBD and evaporative emission requirements of the North American EPA Tier 3 standard, making it known as the "strictest standard in the world". According to the China 6 emission standard, carbon monoxide, hydrocarbons, non-methane hydrocarbons, and nitrogen oxide emissions from light-duty gasoline vehicles will be reduced by approximately 50% compared to the China 5 stage, and particulate matter emissions will be reduced by about 40%. For heavy-duty diesel vehicles, nitrogen oxides and particulate matter will be reduced by more than 60% compared to the China 5 stage. Implementation timeline of the China 6 standard: The China 6 standard was implemented starting in 2020 and is divided into two phases: Phase 1, effective from July 1, 2020. Phase 2, effective from July 1, 2023, requires all vehicles sold and registered to comply with the China 6B standard.
I researched this when buying a new car before. China V is actually China's fifth-stage vehicle emission standard, meaning the country requires stricter control of pollutants emitted by vehicles, such as carbon monoxide and hydrocarbons, which must not exceed the limits. It's much better than the China IV standard. I remember it was introduced around 2017 with the aim of protecting air quality and environmental health. Nowadays, buying China V vehicles is quite common. During vehicle inspections, these cars are required to be equipped with efficient catalytic converters, making the exhaust cleaner. I've been driving a China V car for two years myself and haven't noticed much change in fuel consumption, but the mechanic mentioned that maintaining the emission system is crucial, like regularly changing the air filter, otherwise it might affect performance. In the long run, it promotes industry progress, so everyone should try to choose vehicles with higher emission standards.
