What Fuel Consumption is Considered Fuel-Efficient?
1 Answers
Depending on the engine displacement of different vehicle models, the fuel consumption considered fuel-efficient will also vary with the engine size. For example, for models with an engine displacement below 2.5 liters, a comprehensive fuel consumption of around 7L/100km is generally considered fuel-efficient. Additionally, whether a vehicle is fuel-efficient also depends on factors such as its weight and category. Some fuel-saving tips include: for manual transmission models, coasting in neutral as much as possible while ensuring safety; cleaning carbon deposits in the engine; maintaining engine speed between 2000-2500 RPM, as higher speeds can overload the engine; improving fuel quality to ensure complete combustion in the engine; and maintaining a consistent speed while driving to avoid sudden stops. The safest and most fuel-efficient driving method is maintaining a steady speed in a straight line. The most fuel-efficient speed for small-displacement vehicles is between 60 to 80 km/h, while for medium-displacement vehicles, it's 80 to 100 km/h. In congested streets, try to maintain a safe distance from the vehicle ahead, gently lift the accelerator, and reduce the frequency of braking to minimize fuel consumption.
