There is no better way to achieve maximum fuel consumption efficiency than driving long distances with minimal pressure on the accelerator and performing each action as smoothly as possible. Therefore, highways are the best roads for spending the least amount on fuel, especially if they have stretches that demand little, have no slopes or few steep inclines, and are not very uneven.

Defensive driving is one of the secrets to getting the most out of highway driving. Transportation professionals are always aware that, in anticipating maneuvers that other vehicles might make or that they might need to deal with, such as drivers cutting in front and hitting the brakes, not a drop of fuel will be wasted because they will avoid heavy last-minute acceleration or braking which would later make it necessary to recover speed quickly.

One ally of transportation drivers, especially on roads with several lanes in each direction, is cruise control, a system that allows a speed to be set and the vehicle to maintain that speed automatically. Over the last few years, the Adaptative Cruise Control (ACC) has been extended, such that in addition to maintaining a stable pre-set speed, it can automatically apply the brakes when approaching another vehicle and then accelerate to recover the cruising speed.
