2 Answers
China 4, China 5, and China 6 all refer to vehicle emission standards. Below are the specific details: China 4 Emission Standard: Issued by the Ministry of Environmental Protection on April 15, 2005. Gasoline vehicles began implementing it on July 1, 2010. Diesel vehicles were implemented by vehicle type and region. The final nationwide implementation date for diesel vehicles was July 2013. China 5 Emission Standard: Announced by the Ministry of Environmental Protection on September 17, 2013. Starting from January 1, 2018, all motor vehicles nationwide fully implemented the China 5 emission standard. Currently, Beijing, Shanghai, and Guangzhou have already taken the lead in implementing the China 5 emission standard for gasoline vehicles. China 6 Emission Standard: Starting from July 2021, the China 6 emission standard for heavy-duty diesel vehicles will be fully implemented, marking the comprehensive entry of domestic vehicle standards into the China 6 era, basically achieving alignment with developed countries in Europe and America.
I'm an ordinary person who loves driving, and I'm quite familiar with the concepts of China 4, China 5, and China 6. These are actually China's vehicle emission standards. China 4 represents the fourth stage, China 5 is the fifth stage, and China 6 is the latest sixth stage. The higher the number, the stricter the emission requirements, making it more environmentally friendly. For example, the China 6 standard is currently the strictest, significantly reducing harmful substances in vehicle exhaust, such as particulate matter PM2.5 and nitrogen oxides, making driving more eco-friendly and healthier. When buying a car, pay close attention to this. Some big cities only allow China 6 or China 5 vehicles for registration, so don’t end up with a lower-standard car and run into trouble. I recommend checking the vehicle's environmental compliance list or conformity certificate, which clearly states the emission level. Choosing a higher-standard car not only supports the national Blue Sky Action but also saves fuel and money, makes maintenance easier, and avoids frequent breakdowns that could ruin your travel mood. In the long run, higher-standard cars hold more value in the used car market, giving you confidence when it’s time to upgrade.
