How much fuel does a 2.0T engine consume when idling with AC on for one hour?

With the air conditioning turned on and idling for 1 hour, a 2.0T engine typically consumes approximately 3-4 liters of fuel. When the engine operates in an idling state, the fuel consumption is related to the engine's own displacement. Factors affecting fuel consumption are as follows: 1. Rough roads increase fuel consumption: Poor road conditions or uneven surfaces force the vehicle to drive in low gear for extended periods, inevitably increasing fuel consumption; 2. Using the trunk as storage increases fuel consumption: Treating the trunk as a warehouse and stuffing it with all kinds of items, useful or not, increases the vehicle's weight. It's important to note that vehicle weight is directly proportional to fuel consumption. For every 10% reduction in vehicle weight, fuel consumption decreases by a corresponding percentage; 3. Incorrect driving habits can double or triple fuel consumption: Improper driving habits have the greatest impact on fuel consumption. During driving, especially in heavy traffic, at red lights, or when changing lanes, sudden acceleration and hard braking are the most common issues.
I often drive my friend's 2.0T car and notice that idling with the AC on for an hour consumes quite a bit of fuel, roughly between 1.0 to 1.8 liters. Specifically, idling alone burns 0.8 to 1.2 liters, while turning on the AC adds another 0.2 to 0.6 liters, totaling up to that range. The AC compressor requires the engine to work harder, which spikes the fuel consumption. This also varies depending on the car model and outside temperature—for instance, when it's extremely hot, the AC works harder, burning fuel much faster. Calculating the cost at 7 yuan per liter, it amounts to 7 to 13 yuan per hour. Doing this long-term isn’t just a waste of money; it’s also bad for the car, increasing engine carbon buildup and battery wear, leading to higher maintenance costs. Nowadays, my buddies and I turn off the engine if we’re parked for more than a few minutes, opting to roll down the windows for ventilation instead—it’s more economical, hassle-free, and eco-friendly. In short, if you want to save money on car maintenance, minimize idling and find alternatives for short trips.
