What are the differences between China 5 and China 6?
2 Answers
The differences between China 5 and China 6 are: 1. Different nitrogen oxide emission standards: China 5's nitrogen oxide emission standard is 0.18 grams per kilometer; China 6's nitrogen oxide emission standard is 0.16 grams per kilometer. 2. Different particulate matter concentration emission standards: China 5's particulate matter concentration emission standard is 0.0045 grams per kilometer; China 6's particulate matter concentration emission standard is 0.022 grams per kilometer. 3. Different non-methane hydrocarbon emission standards: China 5's non-methane hydrocarbon emission standard is 0.23 grams per kilometer; China 6's non-methane hydrocarbon emission standard is 0.18 grams per kilometer.
As a car enthusiast, I think the biggest difference between China 5 and China 6 emission standards is that the latter is more environmentally friendly. The China 6 standard imposes much stricter limits on pollutants. For example, nitrogen oxide and carbon monoxide emissions are nearly halved compared to China 5, which is crucial for improving urban air pollution. On actual roads, China 6 vehicles also include RDE (Real Driving Emissions) testing, which simulates real driving conditions to detect emissions rather than relying solely on laboratory data, making the results more reliable. Additionally, China 6 requires higher-quality fuel; regular 92-octane gasoline may not suffice, and 95-octane is needed to reduce particulate matter, but this is more engine-friendly in the long run. Overall, this upgrade can make street air cleaner and reduce the impact of smog on our breathing. As for the economic aspect, buying a new China 6-compliant car might be slightly more expensive, but it holds its value better, while prices for used China 5 cars are starting to decline. This is worth considering when choosing a car.
