What are the differences in power between National V and National VI?
3 Answers
There is no difference in power between National V and National VI. The main differences are: 1. Different carbon monoxide emissions: The carbon monoxide emission of National V is 1,000 milligrams; the carbon monoxide emission of National VI is 700 milligrams. 2. Different emission limits: The emission limit of National V is 0.0045 grams per kilometer; the emission limit of National VI is 0.25 grams per kilometer. National V, fully known as the National Fifth Stage Motor Vehicle Pollutant Emission Standard, and National VI, fully known as the National Sixth Stage Motor Vehicle Pollutant Emission Standard, both regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot emitted from vehicle exhaust.
As a tech enthusiast, from an engine optimization perspective, the power difference between China V and China VI standards isn't significant. China VI has stricter emissions, so automakers incorporate more advanced technologies, such as improved fuel injection systems and particulate filters to clean exhaust. This might make the initial acceleration slightly smoother, but the horsepower output remains as strong as China V because turbocharging has been adjusted, and fuel consumption is actually more efficient. I've driven the same model for comparison, and the acceleration response is almost identical with no noticeable lag. The difference lies in the China VI engine being quieter with less vibration, but the emission components are more complex, potentially leading to higher maintenance costs later. No need to worry about power—technological upgrades ensure performance doesn't drop but actually improves, with no impact on daily driving while reducing pollution emissions.
I drove a China 5 standard car for several years before, and after switching to a China 6 standard one, the power difference is almost negligible. The acceleration is still smooth, and the horsepower is sufficient at high speeds, with hardly any noticeable difference. The main distinction is that the China 6 car is more environmentally friendly and consumes slightly less fuel, saving me a few dozen yuan on gas each month. However, the interior noise has reduced, making the ride more comfortable. The maintenance cost is a bit higher, as the emission system tends to clog and requires regular cleaning, which is time-consuming and costly. Power isn't a major issue, and my driving habits haven't changed. The key point is that after the national policy promoted the China 6 standard, car purchase options have increasingly leaned towards energy-efficient models.
