At what speed is the most fuel-efficient?
1 Answers
The most fuel-efficient speed for sedans is between 60km/h and 90km/h. Cars are most fuel-efficient when traveling at their economic speed. Generally, on highways, exceeding the economic speed leads to increased fuel consumption as speed increases. Methods to save fuel: Minimize the use of brakes. Driving in a 'start-stop' manner is particularly fuel-consuming. When approaching intersections or downhill sections, you can release the accelerator in advance to allow the car to decelerate naturally and stop, which is more fuel-efficient. Reduce the car's load. It is advisable to remove unnecessary items from the car. If the load is reduced, fuel consumption will naturally decrease slightly. Ensure normal tire pressure. If the tires are abnormal, it can also increase fuel consumption. Therefore, if any tire abnormalities are detected, they should be checked promptly. This not only saves fuel but, most importantly, ensures driving safety. Control the optimal engine speed. While driving, the engine speed of most fuel-injected cars is most efficient between 2200 and 2500 rpm. Regardless of the gear, maintain the engine speed around 2200-2500 rpm. Too low a speed makes the car sluggish, consumes fuel without moving, and damages the engine, while too high a speed increases unnecessary fuel consumption and also harms the engine.
