What is the difference between National V and National VI?
4 Answers
The differences between National VI and National V are as follows: 1. Different durability mileage: Compared to National VI, National V increases from 80,000 kilometers to 160,000 kilometers. 2. Different particulate matter particle numbers: Compared to National VI, National V gasoline vehicles have 25% stricter nitrogen oxide limits, and diesel vehicles have 28% stricter nitrogen oxide limits. 3. Different sulfur content: The upper limit of sulfur content in National VI standard gasoline is 50mg/kg, while the upper limit in National V standard gasoline is 10mg/kg. 4. Different implementation times: The implementation time for the National VI standard was December 2014, while the implementation time for the National V standard was December 2017.
I've been driving for several years, and the main difference between China 5 and China 6 lies in emission control. The China 6 standard is stricter, requiring vehicles to reduce more harmful gas emissions, such as carbon monoxide and nitrogen oxides, by about 20% to 50%. This is better for the environment, improving urban air quality and reducing smog days. After the transition from China 5 to China 6, most new cars are equipped with advanced filters like GPF, making the exhaust smell lighter and the startup noise lower when driving. However, the cost may be slightly higher, with new car prices increasing by a few thousand yuan. When considering a car change, you need to factor in your budget and urban traffic restriction policies. Currently, China 6 cars have more stable second-hand value, making them a better long-term investment.
From a technical perspective, I understand that China 5 was the emission standard from several years ago, while the upgraded China 6 is more stringent. China 6 is divided into Phase A and Phase B, with Phase B being even stricter, requiring the installation of new systems like particulate filters to treat exhaust emissions. China 5 vehicles have looser emission limits, making them more prone to issues like black smoke or failing emission tests. After switching to a China 6 vehicle, I noticed a slight improvement in fuel efficiency, as system optimizations allow more distance per liter of fuel. Technological advancements are also pushing automakers to develop hybrid vehicles. Future maintenance might involve checking filters, but it shouldn’t be hard to adapt. For car owners, choosing a China 6 vehicle is more worry-free, especially since it significantly improves the pass rate during annual inspections.
Buying a China VI vehicle costs a bit more than a China V model, with a higher new car price, but currently, the government offers subsidies and tax reduction policies to encourage upgrades. The resale value of China V used cars is dropping quickly, making them harder to sell, especially in cities with license plate restrictions where they are more likely to face limitations. The difference in standards mainly lies in the strictness of emission controls, with China VI better meeting stringent regulatory limits. From an economic perspective, long-term fuel savings reduce expenses, lowering fuel costs. The decision to switch vehicles requires a cost-benefit calculation, and choosing China VI ensures longer worry-free usage.
