How Much Does Using Air Conditioning Increase Fuel Consumption in Summer?

[Sullivan]

For most household cars with engine displacements typically ranging from 1.3 to 2.5 liters and fuel consumption between 6 to 10 liters per 100 kilometers, using air conditioning generally increases fuel consumption by 10-15% of the original rate. Therefore, fuel consumption per 100 kilometers increases by 0.6 to 1.5 liters. Factors affecting fuel consumption include: 1. Rough roads consume more fuel: Driving on congested or uneven roads in low gear for extended periods inevitably increases fuel consumption. 2. Using the trunk as storage increases fuel consumption: Loading the trunk with unnecessary items adds weight to the car, and since vehicle weight is directly proportional to fuel consumption, reducing weight by 10% can decrease fuel consumption by several percentage points. 3. Incorrect driving habits can double or triple fuel consumption: Poor driving habits have the most significant impact on fuel consumption, especially during traffic jams, at red lights, or when changing lanes, where rapid acceleration and sudden braking are most common.
