How to Distinguish Between National V and National VI Standards for Sedans?
2 Answers
The National V emission standard is marked with the Roman numeral "V", while the National VI emission standard is marked with "Ⅵ". When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes details such as the model, color, emission standard, engine number, and chassis number. For used cars, you can check whether it meets National V or National VI standards by searching the vehicle's complete model number on the environmental protection website. Here are several methods to determine whether a car meets National V or National VI standards: 1. Check the vehicle's environmental label: The simplest and most direct method is to look at the vehicle's environmental label, which clearly indicates the standard on the back. 2. Query on the Motor Vehicle Management Center website: Visit the Motor Vehicle Exhaust Pollution Supervision and Management Center website to check. 3. Visit the Vehicle Management Office: Bring the vehicle registration certificate (either the original or a copy) to the Vehicle Management Office for inquiry. 4. Check the vehicle's factory certificate: For new cars, you can refer to the vehicle's factory certificate, but generally, this document is kept at the Vehicle Management Office. Therefore, when buying a new car, it is advisable to make a copy for your records. 5. Roughly distinguish based on the vehicle's registration year: Make an approximate distinction based on the year the vehicle was registered.
As a frequent driver, I find the easiest way to distinguish between China 5 and China 6 emission standards is by checking the vehicle's production year. From experience, the China 6 standard wasn't nationally implemented until 2017, so if your car was manufactured in 2017 or later, it's most likely China 6 compliant. When purchasing a car, don't forget to check the manual or the nameplate under the windshield – the emission standard is usually stated there. China 6 vehicles have stricter pollution controls, emitting significantly fewer pollutants than China 5 vehicles, with particularly higher requirements for nitrogen oxides, making them more environmentally friendly. In such cases, I also like to check the VIN (Vehicle Identification Number), which can be found on the registration certificate. You can input this at the vehicle management office or on online platforms to get detailed information. Don't underestimate this distinction – China 6 vehicles have easier registration processes, higher resale values, and face fewer traffic restrictions in big cities. It's also good to stay updated on policy changes, as places like Beijing and Shanghai have already mandated China 6 standards. When buying a new car, always confirm with the salesperson to avoid future hassles.
