Which is Better: China National V or China National VI Emission Standards?

[KinsleyFitz]

China National V and China National VI emission standards each have their own advantages. Vehicles meeting National V standards offer significant discounts and are more affordable, while National VI-compliant vehicles face fewer restrictions and can be registered anywhere. Below is additional information: 1. Introduction to National V: The China National V Motor Vehicle Pollutant Emission Standard, also known as "National V Standard," has an emission control level equivalent to the Euro 5 standard currently implemented in Europe. The European Union has enforced this standard since 2009, imposing stricter limits on nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM) from motor vehicles. Each upgrade from National I to National IV has reduced single-vehicle pollution by 30% to 50%. 2. Differences: The new standard can reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that new vehicles can reduce annual nitrogen oxide emissions by about 1,000 tons. Additionally, China's National V emission control level is equivalent to the Euro 5 standard currently in effect in Europe.
