w30fe refers to the fuel economy of a vehicle. Introduction to Fuel Economy: Fuel economy refers to the ability to complete a unit of transportation work with minimal fuel consumption. Introduction to Economic Indicators: There are three evaluation indicators for economy: fuel consumption per unit distance traveled, fuel consumption per unit of transportation work, and distance traveled per unit of fuel consumed. In China, testing primarily focuses on the first indicator. Differences in Fuel Economy Indicators: The fuel economy indicators for gasoline are related to engine characteristics, vehicle weight, speed, various motion resistances such as air resistance, rolling resistance, and climbing resistance, as well as transmission efficiency and gear reduction ratios. Therefore, numerical values often differ from actual conditions.
