As a vehicle speed increases, its fuel efficiency tends to drop. Many drivers believe that driving faster helps save time, but it also leads to higher fuel consumption.
Maintaining the right cruising speed puts less strain on the engine and helps in using fuel more efficiently.
This is why keeping your speed balanced is considered essential for better mileage, especially during daily commuting and regular city driving.

Why Does Fuel Mileage Drop at High Speeds?
When a car is driven at very high speeds, the engine has to work much harder. At higher speeds, air resistance increases significantly, forcing the engine to burn more fuel. Additionally, rapid acceleration and frequent braking further add to fuel consumption. Driving fast also reduces the overall efficiency of the tyres and the engine, which gradually leads to lower mileage and higher running costs.

Low Vehicle Speed Can Also Be a Reason
Driving at very low speeds is also not ideal for fuel efficiency. Staying in lower gears for long periods puts extra load on the engine and increases fuel consumption. Frequent stop-and-go driving in traffic further reduces mileage.
Maintaining the correct gear and a steady speed allows the engine to operate more efficiently, helping save fuel and proving beneficial in the long run.
The Right Vehicle Speed for Better Mileage
For most cars, maintaining a speed between 50 and 80 kmph is considered ideal for achieving better fuel mileage.
At this range, the engine operates efficiently with minimal stress, resulting in lower fuel consumption. Smooth driving habits, timely gear shifts, and avoiding sudden acceleration play a crucial role in improving efficiency.
Keeping the vehicle’s speed under control not only helps enhance mileage but also improves overall safety and extends the car’s lifespan, making it a smart choice for everyday driving.
