Does Using the External Air Recirculation Mode Consume More Fuel?

[JackAnn]

Using the external air recirculation mode without turning on the air conditioning or fan does not consume more fuel. It simply opens a flap to allow air to flow in, without any additional fuel consumption. As the name suggests, the external air recirculation mode draws air from outside the vehicle, cools or heats it through the car's air conditioning system, and then blows it into the cabin through the vents to ensure fresh air inside the vehicle. Additional Information: 1. Internal Air Recirculation Mode: The primary function of the internal air recirculation mode is to effectively block external dust and harmful gases from entering the cabin. It is useful when driving through areas with smoke, dust, strong odors, or in heavy traffic, as it prevents harmful exhaust fumes from preceding vehicles. Another benefit is maintaining cabin temperature. 2. External Air Recirculation Mode: This mode allows you to breathe fresh air from outside the vehicle. During long highway drives, the cabin air can become stale and uncomfortable, and opening windows may not be feasible. In such cases, using the external air recirculation mode can bring in fresh air. In winter, if the cabin becomes too warm with the heater on, you can turn off the fan and switch to external air recirculation to maintain a comfortable temperature while still getting fresh air.
