How much does the Civic's fuel consumption increase when the air conditioning is on?

When the air conditioning is on, the Civic's fuel consumption increases by approximately 2 liters per 100 kilometers. Air conditioning fuel consumption: For a car that typically consumes 10 liters per 100 kilometers, turning on the air conditioning will increase fuel consumption by about 2 liters. The impact of air conditioning on fuel consumption is very noticeable, and different fan speeds also have varying effects. Principle of increased fuel consumption: The car's engine essentially powers the air conditioning compressor, so when the cooling air conditioning is turned on, the pressure on the car's engine increases, requiring more gasoline to burn for power. This is why sometimes when the cooling air conditioning is turned on while driving, the car's power feels slightly weaker—because the engine's pressure increases.
