What does the 'Guo Ji' in cars represent?

Car 'Guo Ji' represents the emission standards. The 'Guo Ji' classification is differentiated by letters, with I corresponding to Guo 1, II to Guo 2, III to Guo 3, IV to Guo 4, V to Guo 5, and VI to Guo 6. Currently, Guo 6 is being implemented, which is divided into two phases: Guo 6a and Guo 6b. In cities like Beijing and Shanghai, vehicles are required to meet emission standards higher than Guo 5. Therefore, when purchasing a new or used car, it is necessary to choose a vehicle with Guo 5 or higher emission standards, otherwise, it may not be possible to complete the transfer or drive legally. In second and third-tier regions, vehicles must meet at least Guo 4 emission standards, so when buying a car, one should choose a vehicle with Guo 4 emission standards. In some more remote rural areas, vehicles with Guo 3 and Guo 2 standards are still acceptable.
I used to research automotive emission issues, and the term "Guo Ji" actually refers to our country's emission standard levels, such as Guo I, Guo II, or Guo VI. It primarily controls the amount of pollutants in vehicle exhaust to reduce pollution and protect the environment. Specifically, Guo VI is currently the latest standard, which requires reductions in carbon monoxide, nitrogen oxides, and other substances. Automakers must use more advanced technologies, such as catalytic converters, to meet these requirements. This standard affects daily vehicle use, as higher-emission vehicles like those meeting Guo VI may not be subject to traffic restrictions in cities. If you're an environmental enthusiast, driving such a car can give you peace of mind. The emission standard level of a vehicle is determined by its manufacturing date, with Guo VI generally being implemented after 2019. Regular maintenance of the emission system can extend its lifespan and prevent malfunctions. In short, it's a crucial factor to consider before buying a car, as checking it in advance can help ensure a hassle-free driving experience.
Last time I bought a new car, I asked what this 'National Emission Standard' was. It's essentially the country's control standard for vehicle exhaust emissions. National I is the oldest, while National VI is the latest and most stringent, limiting pollutant emissions. This affects whether you can drive freely in cities—for example, some areas only allow National V or VI vehicles to be registered and licensed. From a practical perspective, choosing a car with higher emission standards might cost slightly more but comes with more environmental subsidies. Cars from different years have different standards, so check the compliance certificate before buying. Cars with better emissions are also healthier to drive, reducing the inhalation of harmful gases. If you're an average person like me, prioritize National VI when choosing a car to avoid future hassles, as policies are getting stricter. Regularly changing the air filter can also help.
