What is the National VI Standard?

[OCarson]

National VI Standard refers to the National Stage 6 Motor Vehicle Pollutant Emission Standards. Under the current circumstances, the National 6 emission standard is divided into National 6A and National 6B stages. Compared to the National 5 emission standard, the National 6 standard imposes stricter requirements and more rigorous limits on pollutant emissions. Additional information: Impacts of the National 6 Emission Standard: 1. Impact on the sales of imported vehicles: The Euro VI emission standard for imported vehicles will conflict with the National 6B emission standard, which will affect the sales of imported vehicles. 2. Challenges for domestic brands: The stricter National 6 emission standard increases R&D costs for domestic brands, leading to corresponding price increases for their vehicles. 3. Boosts the activity of the pure electric vehicle market: The implementation of the National 6 emission standard will inevitably increase the activity of the pure electric vehicle market and boost its sales. 4. Significant impact on the used car market: The National 6 emission standard may cause many potential buyers of used cars to adopt a wait-and-see attitude, severely affecting the resale value of National 5 models.

The China VI standard refers to the sixth phase of the national emission standards, commonly known as China 6. I remember when I bought a car last year, the salesperson specifically highlighted this point, emphasizing that the vehicle was China 6b compliant—both eco-friendly and up to standard. The China 6 standard primarily targets vehicle exhaust emissions, setting very low limits for pollutants such as nitrogen oxides and particulate matter, which are harmful to the air. It is divided into two phases, a and b: phase a was introduced in 2019, and phase b was fully implemented in 2020, much stricter than the older China 5 standard. As an ordinary car owner, I suggest everyone pay attention to this label when buying a new car. China 6-compliant vehicles not only pass annual inspections more easily but may also save on fuel costs in the long run and have higher resale value. Don’t be fooled into buying an older-standard car—it might face driving restrictions or rapid depreciation, which isn’t worth the extra cost.

Speaking of the China VI standard, my understanding is that it's the sixth-stage national emission regulation, an environmental protection measure implemented by the government. I pay close attention to this issue because it directly affects both the environment and our health. The standard requires automakers to improve their technology, significantly reducing PM2.5 and hydrocarbons in vehicle exhaust. With fewer emissions, big cities see less smog, and the risk of lung diseases decreases. Implemented in 2019, the China VI standard's Phase B is even stricter, accelerating the popularity of electric vehicles. Now, driving on the road means fewer emissions and cleaner air, with more blue skies in cities. We should all support this change—choosing China VI-compliant vehicles helps the planet breathe fresher air and benefits future generations.

China VI, simply put, is the China 6 standard, the sixth edition of national vehicle emission regulations. It sets upper limits for pollutant emissions, such as requiring nitrogen oxides to be 50% lower than China 5. Technologically, this has driven automakers to upgrade engines and exhaust systems, employing high-efficiency catalytic converters to meet the standards. Currently, most vehicles on the market comply with China 6b, reducing pollution while also lowering fuel consumption. The implementation of China 6, starting in 2019, has significantly cleaned up new vehicles, making them pass environmental inspections with ease.

Looking at market impact, the China VI standard is the sixth-stage emission regulation system. At its initial implementation in 2019, China VIa prompted inventory clearance of China V vehicles at discounted prices, allowing consumers to purchase at lower costs. Subsequently, with the mandatory enforcement of China VIb, older used cars depreciated, while new car prices remained stable with higher resale value. The entire industry accelerated its shift towards energy-saving technologies, boosting new energy vehicle sales. As an observer, I believe opting for China VI-compliant vehicles is wiser—at least avoiding urban driving restrictions and saving on maintenance hassles.

China VI is essentially the National 6 emission standard, representing the sixth stage of national emission requirements. The sixth stage is significantly stricter than the fifth, aligning with international standards such as Euro 6. Since its implementation in 2019, it has aimed to control air pollution by reducing tailpipe pollutants. The future trend may likely introduce China VII, making China VI vehicles the current stepping stone for environmental compliance. Using such vehicles ensures peace of mind during inspections and reduces concerns over policy restrictions, making it a convenient choice.
