How much fuel does it take to run the car air conditioner overnight?
1 Answers
For vehicles with different engine displacements and tuning, the fuel consumption parameters when idling with the air conditioning on vary significantly. According to relevant tests, under one hour of idling with the air conditioning on: a 1.4L Volkswagen Sagitar consumed 2.5 liters of fuel, a 1.8L Honda Civic consumed 4.6 liters, and a 5.0L Range Rover consumed 6.6 liters. Here's the relevant explanation: Running the air conditioning in P gear does increase fuel consumption because the car's air conditioning compressor is driven by the engine. When the engine operates at low speeds, the proportion of power allocated to the air conditioning compressor increases, resulting in higher engine load.
