Maintaining consistent speeds is a driving practice that can significantly enhance a vehicle's fuel efficiency. When a driver accelerates and decelerates frequently, the engine has to work harder, which often leads to increased fuel consumption. In contrast, driving at a steady speed allows the vehicle's engine to operate more efficiently, optimizing fuel use. This is especially true at moderate speeds, where vehicles are designed to balance power and fuel economy effectively.

In addition to smoother acceleration and deceleration, maintaining consistent speeds reduces the likelihood of unnecessary increases in RPMs, which can also contribute to higher fuel consumption. Therefore, practicing steady driving habits, such as using cruise control on highways when safe, further enhances fuel efficiency and reduces overall emissions.
