What does China 5 and China 6 mean?
2 Answers
China 5 and China 6 refer to the national motor vehicle emission standards, which are respectively: 1. China 5 standard: The fifth stage national motor vehicle pollutant emission standard, with emission control levels equivalent to the fifth stage emission standard currently implemented in Europe; 2. China 6 standard: The sixth stage national motor vehicle pollutant emission standard. China 5 requires that the carbon monoxide emissions of gasoline vehicles should not exceed 1 gram per kilometer, while China 6 requires that the carbon monoxide emissions of gasoline vehicles should not exceed 0.5 grams per kilometer. The emission standards include: China 1, China 2, China 3, China 4, China 5, and China 6. Automobile emission standards refer to the limits on harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and carbon smoke emitted from automobile exhaust.
China 5 and China 6 are emission standard codes set by China for automobiles, specifically designed to control tailpipe pollution. As someone who has been driving for many years, I used to drive an older China 3 vehicle and felt the exhaust fumes were very strong, especially during traffic jams when it felt suffocating. After switching to a new China 6 car, I’ve noticed significantly cleaner emissions, and the air in the city seems better too. The government promotes these standards to reduce smog and harmful gases—the higher the standard, the stricter the restrictions. In cities like Beijing, China 6 vehicles often face no driving restrictions, making them much more convenient. If you’re considering buying a car, I’d recommend prioritizing a China 6 model. Although the new car might cost 10,000 to 20,000 yuan more, it’s worth the money in the long run for both environmental benefits and fuel efficiency.
