Does fuel consumption increase when driving at high speed?
Preventive and Efficient Driving – Observation and Fuel Saving
Explanation
The consumption of **fuel** increases when driving at **high speed** for several reasons:
- From **80 or 90 kilometers per hour**, the vehicle consumes much more fuel. This is because at higher speeds, the engine needs more energy to maintain the pace, which increases fuel consumption.
- Additionally, when driving at high speed, the vehicle faces more **air** resistance. Most of the fuel is used to overcome this resistance, which also contributes to the increase in consumption.
- Maintaining a **constant speed** and avoiding sudden changes in speed is key to efficient consumption. However, at high speeds, it is more difficult to maintain this consistency, leading to higher fuel expenditure.
Therefore, whenever driving at high speed, fuel consumption will increase.
