How to Identify China IV and China V Vehicles?
4 Answers
Check the vehicle's environmental protection label, which has clear markings on the back. Below are the differences between China IV and China V: Exhaust Emissions: Compared to previous standards, China V regulations reduce nitrogen oxide (NOx) emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles compared to China IV. Emission Standards: The China V emission standard reduces nitrogen oxide (NOx) emissions by 28% compared to China IV, and the combined hydrocarbon and nitrogen oxide (HC+NOx) index is lowered by 23%. For diesel vehicles, particulate matter (PM) concentration is reduced by 82%, and the new particulate number (PN) testing is specifically targeted at diesel vehicles, with PN standards only applicable to diesel vehicles.
As a car owner, I usually rely on those official labels to identify China IV and China V vehicles. The key is to check the emission standard markings on the vehicle nameplate and the environmental protection logo on the registration certificate - they clearly print the emission standard codes. For example, China IV is marked as 'GB IV' or similar, while China V is 'GB V'. My old car was purchased in 2015, and I later learned from research that most new vehicles produced after July 2017 were upgraded to China V standard, while earlier models were mostly China IV. This identification method proves quite practical, especially during annual inspections when staff directly verify this information. I've also picked up a useful tip: for vehicles manufactured around 2016, it's best to check manufacturer specifications or environmental protection department databases, as some models might have adopted the new standard earlier. Don't cut corners - carefully review the vehicle manual or Certificate of Conformity to avoid transfer issues later.
When choosing a used car, I pay special attention to the emission standards because China IV vehicles face severe restrictions in some cities. By checking the environmental information page on the registration certificate, such as 'Emission Standard: China V' or 'China IV,' it becomes clear at a glance. Last time I was car hunting, I specifically asked the seller to send me photos of the documents. Combined with checking the VIN on the environmental bureau's official website, I easily avoided buying an older model with high emissions. With current strict policies, China V used cars command higher prices and can also save on environmental taxes. Remember, don’t just take the seller’s word for it—seeing is believing. If necessary, bring a car-savvy friend along for the inspection to protect your rights.
I value environmental protection, so identifying China IV and China V vehicles is basic knowledge. The China V standard is stricter, which can reduce exhaust pollution and benefit environmental health. Checking is quite simple: there is an environmental label on the vehicle's windshield or door frame, indicating China V or China IV. Most vehicles after 2017 are China V, while older ones might be China IV. I often remind people to prioritize China V vehicles and drive fewer high-emission cars to protect our home's air quality.
