Does Using Air Conditioning on Highways Consume More Fuel?

[VanIsabella]

Using air conditioning definitely consumes more fuel than not using it. The difference in fuel consumption between using air conditioning on highways and regular roads is not significant. When driving on highways, it is recommended to use the air conditioning in external circulation mode. The reasons for using external circulation mode for air conditioning on highways are as follows: 1. Highways: When driving on highways, the windows are usually closed, preventing proper air circulation inside the vehicle. Turning on external circulation allows outside air to enter the vehicle, improving the freshness of the air inside. 2. Air Conditioning: During high-speed driving, external circulation has little impact on the effectiveness of the air conditioning. The weakening effect of using external circulation during normal air conditioning use is minimal. 3. Windows: Fogging on the windshield is mainly caused by high humidity inside the vehicle. Using external circulation continuously introduces fresh air, maintaining moderate humidity levels inside the vehicle and reducing the likelihood of fogging.
