What are the differences between China V and China VI?
2 Answers
Both China V and China VI refer to emission standards, and they mainly differ in the following aspects: 1. Sulfur content: The maximum sulfur content for China VI standard gasoline is 50mg/kg, while for China V standard gasoline, it is 10mg/kg. 2. Implementation time: The China VI standard was implemented in 2014, while the China V standard was implemented in 2017. 3. Particle count: Compared to China VI, China V gasoline vehicles have a 25% stricter limit on nitrogen oxides, and diesel vehicles have a 28% stricter limit on nitrogen oxides.
As someone who has been driving for over a decade, the main difference between China 5 and China 6 lies in the emission requirements. China 6 is the national sixth-stage emission standard, which is significantly stricter than China 5. For example, the carbon monoxide limit is nearly halved, and real-world driving emission tests have been added to ensure vehicles emit fewer pollutants during daily driving. I opted for a China 6-compliant car when I upgraded last year, and it feels smoother in terms of responsiveness, though maintenance costs are slightly higher, especially with the occasional need to clean the particulate filter. Overall, China 6 cars are more environmentally friendly and have better long-term resale value. China 5 cars may face driving restrictions in some areas or impact used car prices, so I’d recommend choosing China 6 to avoid hassle. After driving for so long, you’ll understand—policies change constantly, and keeping up with environmental standards is the way to go.
