How to Distinguish Between China 5 and China 6 Standards When Buying a Car?

[StCharlie]

Methods to distinguish between China 5 and China 6 emission standards when buying a car are: 1. The China 5 emission standard is marked with a V; the China 6 emission standard is marked with a Ⅵ, both using Roman numerals. 2. The vehicle acceptance sheet includes the model, color, emission standard, engine number, and chassis number. 3. For used cars, the vehicle's complete model number can be used to check on the environmental protection website. 4. The vehicle's conformity certificate can be carefully reviewed, which includes the specific national standard number referenced during certification. China 5 reduces nitrogen oxide and particulate emissions by 25% and 80% respectively, resulting in an overall emission reduction of 10% to 15% for China 5 vehicles. China 6 imposes even stricter regulations on pollutant emissions.
