Why Does the Car Lose Power When the Air Conditioner is On?

[LeOlive]

Reasons for power loss when the car's air conditioner is on: The car's air conditioner is driven by the engine, and the power of the air conditioning compressor comes from the car's engine. Therefore, running the air conditioner consumes some power, making the car feel sluggish and underpowered when accelerating. This is a normal phenomenon. The car's air conditioning compressor is driven by the engine. According to the law of energy conservation, when the engine burns the same volume of gasoline, the power efficiency is higher when it only provides propulsion compared to when it both provides propulsion and drives the air conditioning system. For vehicles with larger displacements, the impact of the air conditioner may be less noticeable. So, it's certain that using the air conditioner in summer affects the car's power, but there's no need to worry.
