However, when driving at higher speeds, especially above 80 kilometers per hour, it is advisable to keep the windows closed and turn on the air conditioning. In this case, it is essential to avoid opening the windows in order to concentrate the fresh air in the vehicle and avoid waste.

If you open the windows with the air conditioning on and the car is traveling above 80 kilometers per hour, resistance is created which has a negative impact on fuel consumption. Numerous tests have shown that you can save up to 35 euros per tank of fuel on a long distance journey by using the window trick.

Tips to save on consumption
However, it is also advisable to follow other tips to save fuel and at the same time use the vehicle’s air conditioning to cool down on hot days.

It is not recommended to accelerate and decelerate frequently because these two movements require a lot of energy from the vehicle and therefore fuel consumption increases significantly. Another tip for saving fuel is to drive at as constant a speed as possible to avoid sudden braking and the resulting loss of fuel consumption.

As we have seen, using the window trick to reduce fuel consumption is simple and allows you to use the air conditioning while enjoying the coolness inside the vehicle. If you follow the other tips as well, you’ll save even more on fuel consumption and spend less money on fuel, which is important given the dramatic increases that have occurred recently.
