What do China V and China VI mean for vehicles?
3 Answers
China V for vehicles refers to: the National Fifth Stage Emission Standard for Motor Vehicles, which requires particulate matter emission limits to be below 0.0045g per kilometer. Additionally, it mandates reductions in the emissions of gases such as carbon monoxide, hydrocarbons, and nitrogen oxides from exhaust. This standard is equivalent to the fifth-stage emission level for light-duty vehicles implemented in Europe. China VI for vehicles refers to: the National Sixth Stage Emission Standard for Motor Vehicles, which sets particulate matter emission limits between 0.025g and 0.060g per kilometer. Overall, the pollutant emission limits are 40% to 50% stricter compared to China V. It also stipulates that if a vehicle's emissions-related components fail or are damaged within 3 years or 60,000 kilometers, leading to excessive emissions, the automobile manufacturer is responsible for all costs related to repairs and replacement of parts, effectively safeguarding the rights of vehicle owners.
China V and China VI refer to our country's control standards for automobile pollutant emissions. The number represents its level - the higher the number, the stricter the standard and the greater the protection for air quality. China VI can be considered the most advanced emission requirement currently, tightening pollutant limits by nearly half compared to China V. For example, controls on carbon monoxide and nitrogen oxides have been doubled. Nowadays, newly purchased vehicles must basically meet China VI standards, though China V vehicles can still operate on roads, albeit with potentially greater depreciation in used car prices. Each upgrade reflects our efforts in advancing automotive environmental protection technologies, as winning the Blue Sky Defense Battle depends on every detail.
I personally pay a lot of attention to environmental protection, so I'm particularly concerned about vehicle emission standards. China 5 is the fifth-stage emission standard fully implemented in 2017, while China 6 is the stricter sixth-stage standard launched in 2019. Simply put, China 6 imposes more stringent regulations than China 5, requiring lower levels of pollutants in vehicle exhaust. For example, China 6 vehicles are equipped with a GPF (Gasoline Particulate Filter) for exhaust treatment, which is not mandatory for China 5 vehicles. Nowadays, more and more China 6 vehicles are on the road, which are more environmentally friendly to drive. In the future, they may also enjoy policy benefits, such as exemptions from driving restrictions in some cities for China 6 vehicles.
