Fuel Saving Tips: Opening windows in the city is beneficial, drive with AC on on the highway; Know details

Fuel Saving Tips: In today’s time, amidst rising fuel prices, every car owner wants better mileage. In such a situation, the question often arises whether it is better to walk with the windows open or keep the AC on. There is no direct answer to this, as it completely depends on your driving speed and conditions.

City (less than 40 km/h): Open windows, keep AC off
If you are traveling at 30–40 km/h in city traffic, opening the windows is a better option. Aerodynamic drag is very low at this speed, due to which there is no additional pressure on the engine. On the contrary, when running AC, the engine has to use more power to run the compressor, which increases fuel consumption. So, if the weather is fine then driving with the windows open in the city is good for mileage.

Highway (above 80 km/h): Keep windows closed, AC on
The situation changes as soon as your speed goes above 60–80 km/h. At high speeds, open windows force air into the car, creating a “parachute effect.” This drag effect pulls the car backwards and the engine has to work harder. In this situation, it is better to close the windows and run the AC, because this makes the car run smoothly and saves fuel.

Understand with easy example
Think of it like you’re running with an umbrella. If you walk slowly, the umbrella has no effect, but if you run fast, it pulls you back. Open windows in a car also have a similar effect at high speed. Therefore, for better mileage, always take decisions according to the speed and keep the tire pressure of the car correct.

Drive smooth and avoid acceleration
Smart driving is choosing the right option at the right time. Open the windows in the city and use the AC on the highway—this simple mantra is good for both your pocket and the car.
