How many more years can a National IV emission standard vehicle be driven?

[LePeyton]

As long as the vehicle is in good condition, a National IV vehicle can continue to be driven, but some cities may impose driving restrictions on National IV vehicles. China has clear regulations that do not set a mandatory retirement period for private passenger vehicles, only stipulating "guided retirement" after reaching 600,000 kilometers. Additionally, light trucks and heavy trucks have a mandatory retirement period of 10 years, which can be extended up to 5 years, meaning the maximum mandatory retirement period for National IV trucks is 15 years. The National IV emission standard was implemented in 2011 and lasted until the introduction of the National V standard in 2018. Vehicles produced between 2011 and 2017 generally comply with the National IV standard. The National IV standard requires emissions of various pollutants to be approximately 50% lower than those of the National III standard. The National IV emission standard is China's fourth-stage motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, vehicle emissions are controlled and reduced to levels below the specified standards.

How long a China IV vehicle can still be driven really depends on local policies! In big cities like Beijing and Shanghai, where traffic restrictions are the strictest, China IV vehicles might gradually be banned from entering central urban areas in the next five or six years. However, third- and fourth-tier cities have far fewer restrictions—my old China IV Jetta has been running smoothly in a small county for fifteen years and still passes annual inspections. Regular maintenance is a must, and never remove the catalytic converter—passing emissions tests is the key. As long as it passes inspections and stays in good condition, driving it for another seven or eight years shouldn’t be a problem. Still, it’s wise to keep an eye on local environmental regulations, as some cities have already started expanding restricted zones for China IV diesel trucks.

I've been running a repair shop for over a decade, and owners of National IV vehicles often ask about this. Currently, there's no mandatory scrapping period for private cars—the key is passing the annual inspection. The core lies in three maintenance points: clean the fuel injectors every six months to prevent carbon buildup, don't slack on air filter replacements, and change aging spark plugs promptly. With increasingly strict tailpipe emission tests during inspections nowadays, I've seen many National IV vehicles fail due to faulty oxygen sensors. As long as emissions meet standards without black smoke, driving normally for a decade or more is entirely feasible. However, truck owners should note—multiple provinces have started restricting National IV diesel vehicles from entering logistics parks.

Just bought a used China IV car and feeling anxious? Actually, there's no need to worry at all. Currently, 90% of regions across the country still issue green labels normally for China IV vehicles. My own 2013 Focus passed the inspection last year after replacing the catalytic converter. The key lies in driving habits: avoid short trips with cold starts and immediate shutdowns, take a monthly highway drive to clear carbon deposits, and using 95-octane gasoline actually improves fuel efficiency and reduces knocking. As long as you're not commuting in the core areas of first-tier cities, it can easily last beyond 2030. There are still many premium China IV cars circulating in the used car market.

To be honest, how long a China IV vehicle can last largely depends on where you drive it. In provinces like Hainan that are pushing for full electrification, the phase-out will definitely be faster. But here in my repair shop in a western mountain town, many 2008 China III trucks are still hauling goods in the hills. Currently, the government mainly restricts diesel trucks, while gasoline passenger cars are less affected. Last week, I helped a customer inspect a 2009 Corolla - after replacing the oxygen sensor, its emission readings outperformed some China V vehicles. My advice? Install a vehicle monitoring app to track combustion efficiency in real-time. Timely repairs when issues arise are far better than unnecessary worries.

From the perspective of a 1995 automotive editor: Judging from the phase-out cycle of China III vehicles, China IV vehicles can definitely last until 2030. However, policy trends are changing. Cities like Beijing, Shanghai, Guangzhou, and Shenzhen have already restricted the licensing of China IV trucks, and Jiangsu stopped approving operating permits for China IV diesel vehicles last year. The good news is that the Ministry of Environmental Protection has clearly stated that it will not ban privately-owned China IV gasoline vehicles. What really needs attention is the inventory of spare parts. For example, our magazine's old Tiguan had to wait three months last year for a replacement OEM ECU. It is advisable to set aside sufficient maintenance funds, and choosing older vehicles with metal fuel tanks tends to be more durable.
