The car’s make, model, engine size, weight, and aerodynamics, among other things, all affect what speed is most fuel-efficient for it. The most fuel-efficient speed range is typically thought to be between 45 and 65 mph (or 70 and 105 km/h) or mph (or kph). However, this can differ from car to car.
The point where car engines perform most effectively frequently occurs at a moderate speed. At very low speeds, the engine may not operate as efficiently, and at very high speeds, the quantity of drag (air resistance) significantly increases, requiring more power to overcome it.

Cars are frequently built to be fuel-efficient at average highway speeds, which explains why driving on the highway frequently results in higher fuel economy than in cities. However, improvements in engine technology, aerodynamics, and gearbox design have enabled fuel efficiency advances over a variety of speed ranges.

It’s important to keep in mind that actual road conditions could be different and that other elements like traffic, elevation, weather, and driving habits will affect how efficiently your automobile uses fuel.
