What is the difference in fuel consumption between China V and China VI?
3 Answers
China VI gasoline contains 10% more ethanol in its additives, which is equivalent to 10% less gasoline content. Under the premise of maintaining the same vehicle configuration, it can be said that China VI has higher fuel consumption, but China VI gasoline is also relatively cheaper. The following is a related introduction: 1. Emission standards: As global environmental pollution problems become increasingly severe, countries around the world are implementing stricter emission standards, which is greatly beneficial for protecting the Earth's environment. 2. Exhaust treatment: Under strict emission standards, automakers will actively develop new technologies to reduce engine exhaust emissions.
The difference in fuel consumption between China V and China VI mainly stems from the upgrade in emission standards. The China VI standard is stricter, requiring lower pollutant emissions, which indirectly drives automakers to optimize engine efficiency. For example, China VI vehicles commonly adopt direct injection technology or turbocharging systems, achieving more complete combustion and directly reducing fuel consumption. Meanwhile, the introduction of the WLTP test cycle, which is closer to real-world driving conditions than the NEDC used for China V, provides more accurate and realistic fuel consumption data. In actual driving, China VI vehicles average 0.5 to 1 liter less fuel consumption per 100 kilometers, especially in urban traffic congestion where start-stop systems play a significant role. Overall, fuel efficiency improves by approximately 5-10%, saving money while being environmentally friendly, making upgrading to a new vehicle a wise choice.
As an ordinary car owner who has driven two generations of vehicles, I do feel that the fuel consumption under the China VI emission standard is indeed better. My previous China V car consumed over 8 liters per 100 kilometers, but after switching to a China VI model, it dropped to around 7.5 liters, saving money on my daily commute. The difference isn't noticeable day-to-day, but it adds up to several hundred yuan in fuel savings annually. The start-stop system helps a lot in city driving, and highway performance is smoother too. While the emission standards target pollution, technological advancements have made the overall system more efficient—saving on fuel costs while reducing air pollution, making driving more pleasant.
