Does using the car's air conditioning with the windows closed save fuel?

Any driver attentive to details has already heard or noticed that activating the air conditioning increases fuel consumption. fuel of any automobile.

This happens because the cooling system compromises part of the vehicle's power, which starts to demand greater fuel consumption to keep it in operation.

To try to reduce this effect, some drivers defend the practice of driving with the windows closed. According to these people, keeping the windows closed improves the aerodynamics of the vehicle, which makes it easier to drive.

Still according to the defenders of the practice, this lighter driving would reduce the pressure caused by the car's cooling system, reducing fuel consumption.

But, does driving with the windows closed reduce fuel consumption?

The answer to this question can vary greatly, as it will depend on how and where the vehicle will be used.

In the case of drivers who travel only on urban roads, at speeds below 60km/h, it is correct to say that keeping the windows closed while the air is on makes no difference.

However, when the car is used on roads, the premise of the relationship between improved aerodynamics and reduced fuel consumption is confirmed, at least in parts.

This is because vehicles generally travel at speeds greater than 100km/h on highways and, at that speed, any effort means a great improvement in the vehicle's aerodynamics, which translates into lower fuel consumption. fuel.
