2 Answers
Methods to distinguish between China V and China VI vehicles: 1. Query on the Motor Vehicle Environmental Protection Website; 2. Inquire at the Vehicle Management Office; 3. Check the vehicle's environmental protection label; 4. Examine the vehicle's factory certificate. China V and China VI refer to standards established to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China, aiming to prevent pollution from exhaust emissions of compression-ignition and gas-fueled ignition engine vehicles, protect the ecological environment, and safeguard human health. The differences between China V and China VI include: 1. Different implementation times: China V standard was implemented in December 2017; China VI standard was implemented in December 2014. 2. Different sulfur content regulations: China V standard stipulates no more than 10mg per kilogram; China VI standard stipulates no more than 50mg per kilogram.
Having driven for over a decade, I'm well-versed in distinguishing between China 5 and China 6 emission standards. The most reliable method is checking the vehicle's nameplate, usually located in the engine compartment or door edges, which displays the environmental label marked 'China V' or 'China VI'. When buying used cars, I always ask sellers to show the registration certificate or conformity certificate, as these documents print the emission standard. Another way is to check the manufacturing year: most vehicles produced after July 2019 are China 6, while earlier models are typically China 5. VIN code checks are even more convenient—just scan with a car app for instant details. Never rely solely on dealers' claims; verifying personally saves trouble. China 6 has stricter emissions, reducing environmental impact, especially avoiding driving restrictions in big cities. I recommend making it a habit to glance at the nameplate before getting in the car.
