How much fuel is consumed by idling with the air conditioning on for 1 hour?

Idling a car with the air conditioning on for about 1 hour consumes approximately 2 liters of fuel. Here are the specific details regarding fuel consumption: 1. Fuel Consumption: Large-displacement motorcycles consume as much fuel as family cars. 2. Comparison: A fuel consumption of 6 liters per 100 kilometers, on the same route, a motorcycle consumes 1.6 liters, while an Octavia consumes 7 liters. Sports cars usually have much higher throttle inputs compared to street cars, leading to higher fuel consumption. The fuel consumption of a liter-class sports car during aggressive acceleration or high-speed runs is comparable to the combined fuel consumption of a 3.0L car. 3. Fuel: Both motorcycles and most cars use gasoline, so the energy from the fuel is the same. The relatively higher fuel consumption of motorcycles comes from high wind resistance, compact structures that leave no room for fuel-saving technologies, and design philosophies that emphasize high RPM power output.
Last time I was waiting at the gas station in my 2.0T car, I tested the fuel consumption out of boredom. With the AC on and idling for one hour, the trip computer showed about 1.8 liters of fuel consumed. This number can vary significantly between different vehicles - a small-displacement car might only need 1.2 liters, while a large-displacement SUV could consume up to 3 liters. Two key factors determine this: first, the power of the AC compressor (maximum cooling consumes 30% more fuel than minimum fan speed); second, the engine's age (my friend's decade-old car burns half a liter more than mine under the same conditions). Actually, the biggest issue with idling with AC isn't the fuel cost, but carbon buildup - I now avoid it whenever possible.
