How much does car air conditioning increase fuel consumption in summer?

[Kayden]

Normally, car air conditioning accounts for about 20% of engine power. For a vehicle with an average fuel consumption of 10 liters per 100 kilometers, turning on the air conditioning will increase fuel consumption by approximately 2 liters. Additional information: 1. Principle: Air conditioning operation consumes engine power, leading to increased fuel consumption and "reduced vehicle power." 2. Other influencing factors: The exact increase in fuel consumption also depends on the specific vehicle model, engine displacement, and even factors like speed and road conditions. 3. Ventilate before turning on the air conditioning: In summer, the interior temperature of the car is high. Turning on the air conditioning immediately after entering the car not only results in poor cooling efficiency but also increases the initial operating pressure on the engine. It is best to open all windows for ventilation first and then turn on the air conditioning.
