How much does using air conditioning affect fuel consumption compared to not using it?

[MaggieDella]

Using air conditioning can consume 20% to 40% of the fuel in the car. Here are some related expansion materials: 1. Relationship between air conditioning and engine displacement: The larger the engine displacement, the more fuel is consumed when using air conditioning. 2. Relationship with speed: If driving on the highway, using air conditioning does not consume much fuel, whereas in urban areas with slower speeds, fuel consumption increases. 3. Relationship with outdoor environment: According to professional surveys, the higher the outdoor temperature, the higher the fuel consumption. 4. Fuel-saving methods: In summer, when driving, you can first open a row of windows to let out some hot air before turning on the air conditioning. This saves fuel and cools the car quickly. Additionally, not carrying too much in the trunk and reducing the vehicle's weight can also help save fuel.
