When will China VI be implemented?

[VanFaith]

China VI is divided into two standards, each with its own implementation time, as follows: 1. China VI a. Starting from July 1, 2020, light-duty vehicles will be required to comply with the China VI a emission standard. 2. China VI b. Starting from July 1, 2023, light-duty vehicles will be required to comply with the China VI b emission standard. However, many provinces and cities have implemented it ahead of schedule. The implementation time may vary according to local regulations: 1. Guangzhou: Light-duty vehicles will implement China VI starting from January 1, 2019. 2. Jiangsu: All gasoline supplied will comply with China VI starting from October 1, 2018. 3. Guangdong: China VI diesel has been on the market since July 1, 2019. 4. Shandong: The China VI emission standard for motor vehicles will be implemented province-wide starting from July 1, 2019. 5. Shenzhen: China VI will be fully implemented in January 2019. Fuel vehicles with emissions below this standard will be restricted from sale, purchase, and road use.

I remember the China VI emission standards were implemented in two phases. The nationwide China VIa standard for light-duty vehicles officially started in July 2020, when many friends rushed to buy China V vehicles before the implementation. Then, by July 2023, the stricter China VIb standard was rolled out nationwide, with particularly stringent exhaust emission checks during this phase, requiring upgrades to catalytic converters. However, major cities like Beijing and Shanghai implemented it earlier, as early as 2019. When changing cars, it's important to pay attention to the manufacturing date, as registration requirements may vary by year, and it's even more crucial to check the environmental label when buying a used car. Nowadays, most new cars on the road are China VIb compliant.

From the perspective of automotive maintenance, the implementation timeline of China VI emission standards directly impacts repair parts availability. Nationwide, China VI-A took effect in July 2020, with an upgrade to China VI-B scheduled for July 2023. However, major cities adopted the standards earlier - my cousin working in Shenzhen's auto parts industry reported all new vehicles there already complied with China VI standards back in 2019. The most significant technical change was the addition of particulate filters, making exhaust system repairs considerably more complex than for China V vehicles. When maintaining older vehicles, pay special attention to parts compatibility. Never compromise by installing mismatched catalytic converters just to save costs, as this will inevitably lead to emission test failures during annual inspections.

China's Stage 6 emission standards are implemented in two phases: Stage 6a was rolled out nationwide in July 2020, and Stage 6b will be fully adopted in July 2023. As a used car appraiser in a small northern city, the most noticeable impact I've observed is the accelerated depreciation of Stage 5 vehicles. For instance, a brand-new Stage 5 car purchased in early 2020 lost 20% of its value within six months, as many consumers worry about difficulties in reselling later. The color of the environmental labels also differs, with green-label Stage 6 cars being more popular in restricted zones. If your budget allows, I recommend directly purchasing a Stage 6b vehicle, as it will undoubtedly have better resale value when you decide to change cars in the future.

As a veteran driver with 20 years of experience, I remember the China VI emission standard was introduced in the summer of 2020, initially called China VIa. Three years ago in 2023, it was upgraded to China VIb. However, enforcement was more relaxed in our fourth-tier city, with strict inspections starting half a year later. The impact is that we now have to refuel at major gas stations, as substandard fuel from small stations tends to clog the exhaust pipe. Once, I misfueled and triggered the malfunction indicator lamp—the mechanic said the aftertreatment systems in China VI vehicles are far more sophisticated. While new cars today do have lower fuel consumption, maintenance costs have risen significantly.

The China VI emission standard implementation timeline is clearly defined: China VIa in July 2020, followed by nationwide rollout of China VIb in July 2023. As someone focused on new energy vehicles, I've noticed this policy unexpectedly boosted hybrid models. Traditional fuel vehicles require additional exhaust treatment devices to comply, increasing both weight and cost. In contrast, plug-in hybrids easily pass inspections by meeting pure electric range requirements. Recently, I've been recommending hybrids to friends for car selection - they comply with emissions while eliminating range anxiety. Post China VIb, even pure fuel vehicles' engine sounds became muffled during acceleration, which engineers attribute to more conservative tuning for emission compliance.
