Idling car’s fuel consumption with AC on for one hour measured

Did you ever get the tip to turn off the AC to increase the fuel efficiency of your vehicle? Well, it is true that switching on the air conditioner will reduce the fuel efficiency of the vehicle but what about the car using fuel while idling with the AC turned on? Well, here is a test done on video and it clearly shows how much fuel a vehicle uses while idling and the AC turned on.

The video uploaded by Arun Pawar shows the test. He starts the video by explaining how he got the idea after there was a power cut for more than two days. He planned to test how much fuel is consumed by the vehicle when it is idling with the AC turned on. This is a pretty interesting test as many of us have thought that AC consumes a lot of fuel while idling. Since most of us drive in the city traffic conditions, most of us stop at the traffic signals for long times and wonder how much the vehicle has consumed during that period.

To check how much fuel is consumed by the vehicle while idling, Arun Pawar filled the vehicle to the brim and drove back to his house. The car was kept on with a timer for an hour with the air-conditioner turned on. Depending on the fuel consumed by the vehicle in an hour, we can calculate the how much a vehicle can consume during shorter or longer intervals.

After returning to home, he kept the vehicle on idling for an hour and then added 20 minutes more. Post that, he drove the car to the same fuel station to fill the tank to brim. After filling the fuel to the brim and calculating the results, he found out that the Marui Suzuki Baleno petrol, consumed about 1.66 litre of fuel, which is worth Rs 130. Which means that keeping the vehicle turned on for an hour will cost around Rs 100. Small amount of fuel was consumed while driving the vehicle to and fro from his home to the fuel station. Arun Pawar says in the video that the distance between his home and the fuel station is about 8 km only.

The Maruti Suzuki Baleno used by the person for this test is powred by a 1.2-litre naturally-aspirated perol engine that generates a maximum power of 83 Bhp and peak torque of 115 Nm. It is the manual version of the car. Now depending on the engine size and the vehicle, the result may come out differently but it should not very different from this one. Also, it should be noted that during humid conditions or hot weather, the AC has to work extra to extra the moisture from the air and keep the cabin cool. So if you’re in a cold and dry condition, the AC will not have to work so much and will use less amount of fuel. So it dependent on the weather condition and of course, the vehicle itself.
