How does the speed at which you travel affect fuel consumption?

Question

DentroTest · Accepted Answer

There is a direct relationship between speed and fuel consumption: at higher speed, the engine has to work at a more demanding rate to overcome aerodynamic drag, which grows with the square of the speed. As a result, the vehicle burns more fuel to maintain that pace. That is why it is correct to say that higher speed means higher consumption. Claiming that speed has no influence ignores the laws of physics of motion, and holding that higher speed means lower consumption describes an inverse relationship that does not occur under normal driving conditions.
