As early as 2019, some automakers began producing China 6 models. By mid-2020, all automakers had ceased production of China 5 models, and all newly launched models were China 6 compliant. More information about China 6 emissions is as follows: 1. China 6 Emission Standards: The emission limits for China 6A are: carbon monoxide 700mg/km, non-methane hydrocarbons 68mg/km, nitrogen oxides 60mg/km, PM fine particles 4.5mg/km, etc.; China 6B: carbon monoxide 500mg/km, non-methane hydrocarbons 35mg/km, nitrogen oxides 35mg/km, PM fine particles 3mg/km, etc. 2. Impact After Implementation: After the implementation of the China 6 standard, it will only affect the registration of new China 5 vehicles. Already registered and annually inspected China 5 vehicles will not be affected in normal use.

















I clearly remember seeing China 6 emission standard vehicles emerging by the end of 2019, as I was to buy a new car back then. When visiting several 4S stores, the salespeople were actively promoting these new emission standard vehicles. They explained that China 6 was implemented to protect the environment, with the national standard being rolled out in two phases: China 6a officially starting in July 2020, and a full upgrade to China 6b by 2023. The benefits included cleaner emissions and reduced air pollution, though the prices were slightly higher than older models at the time, and there was an adjustment period for the power performance. Looking back now, buying a China 6 vehicle was definitely worthwhile—it's more environmentally friendly and safer for long-term driving. I recommend paying attention to the production date marked with 'CN6'.

As a car enthusiast, I've been closely following the rollout of China 6 vehicles: automakers began R&D in 2018, with models gradually hitting the market for trial in 2019. Technically, the standard is divided into China 6a and China 6b—the former was fully implemented by July 2020, while the latter becomes mandatory in 2023. Key upgrades include optimized exhaust treatment systems, such as improved catalytic converters that reduce PM2.5 emissions. Having test-driven early versions at auto shows, I noticed slightly altered throttle response but better fuel efficiency. This iteration reflects environmental trends, with automakers planning ahead. For buyers, I recommend checking official websites or vehicle certificates to confirm compliance with the new standards.

In major cities like Beijing and Shanghai, China 6 vehicles were introduced as early as the beginning of 2019 due to local policies implementing emission standards ahead of schedule. Nationwide, July 2020 marked the official starting point, and now virtually all new vehicles comply. Having personally experienced this transition, I noticed significant regional time differences—always check local implementation timelines before purchasing. While these standards are beneficial for reducing pollution, pay attention to the production date when to avoid confusion.

China VI vehicles were introduced in response to the national call for environmental protection, implemented in phases starting from 2020, first with China VIa and then China VIb by 2023. I care about this topic because it promotes clean technologies, such as reducing nitrogen oxide emissions and improving air quality. Automakers across regions have been launching new models since 2019, with subsidies encouraging the purchase of new energy or China VI-compliant vehicles during car purchases. As an environmental supporter, I believe that switching to new standard vehicles early can benefit society, and in the long run, the costs are offset by fuel consumption optimization.

If you're to buy a new car, China VI models have been rolling out since 2019, mainly divided into China VI A and China VI B versions. I recommend choosing products from 2020 onwards, as they meet national standards and are safer. In practice, pay attention to the vehicle identification and production date. Major brands usually had trial production as early as 2018, and currently, buying a China VI B model offers the best value with strong future compatibility. When purchasing, consider emission performance—don't just focus on price. Options that are fuel-efficient and environmentally friendly are more cost-effective in the long run.
