A car is most fuel-efficient on the highway when it is traveling at a moderate and consistent speed, typically around 50-60 miles per hour. This is because the engine is operating at its optimal efficiency at this speed, resulting in better fuel economy. Driving at higher speeds can decrease fuel efficiency due to increased air resistance, while driving at lower speeds may cause the engine to work harder and use more fuel. Therefore, maintaining a steady speed within the optimal range is key to maximizing fuel efficiency on the highway. **

The most fuel-efficient speed for a vehicle is typically around 50-60 miles per hour. At this speed, the engine is operating at its most efficient level, resulting in better fuel economy. Driving at higher speeds increases air resistance, which requires more fuel to maintain the same speed. Therefore, driving at a moderate speed is the most fuel-efficient option. **
