How to distinguish between China V and China VI emission standards for cars?
2 Answers
Methods to distinguish between China V and China VI emission standards for cars are: 1. Check the vehicle's factory certificate; 2. Refer to the vehicle's environmental standard list; 3. Examine the vehicle conformity certificate. The differences between China V and China VI are: 1. Different carbon monoxide emission levels: China V allows 1000mg; China VI allows 700mg. 2. Different emission limits: China V's limit is 0.0045 grams per kilometer; China VI's limit is 0.25 grams per kilometer. China V stands for the National Fifth Stage Emission Standard for Motor Vehicle Pollutants, while China VI stands for the National Sixth Stage Emission Standard for Motor Vehicle Pollutants. Both standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot.
I usually rely on a few simple and practical life hacks to distinguish between China 5 and China 6 emission standards. First, I check the environmental label in the upper right corner of the car's windshield, which clearly states the emission standard category. China 6 labels usually have new numbers or updated dates. Alternatively, I look for information on the new car invoice or certificate of conformity, where China 6 vehicles are explicitly marked. When buying a used car, I pay special attention to this because I worry that China 5 vehicles might be banned in some restricted cities like Beijing and Shanghai. Another method is to use the vehicle's VIN number to check on government websites or apps—just enter it, and you'll get instant results. This is super useful for doing homework before buying a car to avoid being scammed. Another reliable way is to check the production date. The China 6 standard was fully implemented after 2019, so most new cars after that year meet the standard, while older models might still be China 5. In short, cross-check multiple sources instead of relying solely on verbal information. Only with accurate data can I drive with peace of mind.
