What is the difference between National 4 and National 5 vehicles?

[SanGriffin]

National 4 and National 5 vehicles differ in the following aspects: 1. Price difference: National 5 vehicles are equipped with additional components compared to National 4, and automakers incur extra costs from vehicle declaration, various tests, and production, resulting in National 5 vehicles being significantly more expensive than National 4 vehicles. 2. Road access rights and entry restrictions: Many local policies impose traffic bans on vehicles with lower emission standards, and some older vehicles with outdated emission standards may even be completely prohibited from road use, leading to restricted access or limited driving areas. 3. Residual value difference: Due to factors such as scrapping deadlines, road access restrictions, and entry limitations in certain areas, vehicles with the same condition but different emission standards may have vastly different residual values. Additionally, vehicles with excessively low emission standards are harder to sell.

When it comes to the difference between National IV and National V vehicles, as someone who frequently pays attention to urban air quality issues, I feel the main changes are largely environmental. National IV vehicles have less stringent emission standards, emitting quite a lot of pollutants when driven, such as particulate matter and nitrogen oxides, which are particularly prone to worsening smoggy days. National V vehicles are much stricter, controlling emissions much better and significantly reducing air pollution, making it feel like they contribute more to the surrounding environment when on the road. The government's push for this standard aims to protect health, and now many cities' traffic restriction policies favor National V vehicles. When I changed my car, I prioritized choosing a National V vehicle, and I've also heard that it encourages more people to switch to new energy vehicles. In the long run, fewer emissions mean cleaner air and an improved daily experience.

From a technical perspective, the differences between National IV and National V standards are most evident in the engine and aftertreatment systems. National IV primarily uses basic catalytic converters with relatively lenient emission limits. In contrast, National V imposes stricter requirements, mandating advanced technologies like SCR systems or DPF traps, which significantly reduce harmful gases and particulate matter. These systems require periodic additions such as AdBlue during operation. This design enhances overall vehicle efficiency, offering better durability during maintenance despite higher initial costs. Based on my daily experience with vehicles, National V engines are better optimized, slightly improving fuel efficiency. These differences also affect used car values—simply put, the technological upgrades make daily driving greener and more stable.

Having driven for many years, I've experienced both National IV and National V vehicles, with the biggest differences noticeable in practical details. National V cars are generally quieter and smoother, with fuel consumption similar to or slightly better than National IV models, and significantly reduced engine vibration for a more comfortable drive. The upgraded emission controls mean fewer restrictions in urban areas and much easier resale as used cars. While there aren't major practical issues with National IV vehicles, choosing National V during the transition period is more reliable as environmental regulations continue to tighten.

From an economic perspective, comparing China IV and China V standards: China V vehicles have a slightly higher purchase price, but their better fuel efficiency and lower maintenance costs may offset this. In the used car market, China IV vehicles depreciate faster due to outdated standards, resulting in lower resale values. China V vehicles retain their value better and are easier to resell. If you can utilize policy subsidies when purchasing a China V vehicle, it becomes more cost-effective. In the long run, the overall cost balance makes China V vehicles more economical and hassle-free.

The policy promotes the adoption of the China 5 standard to phase out highly polluting vehicles. China 4 vehicles emit more pollutants, significantly impacting the environment, while China 5 vehicles notably reduce pollution, supporting sustainable development. On a societal level, this drives technological advancements in the industry, paving the way for electrification. Daily cooperation is crucial for improving air quality, and urban traffic restrictions also become fairer. The long-term transition is the direction of progress.
