Do You Use More Gas with Windows Down or AC On?
When driving, there are two main ways to cool down your car: rolling down the windows or turning on the AC. But which one uses more gas?
Using the AC
The AC system is powered by the car's engine, so it will always use more gas than rolling down the windows. The amount of gas used will vary depending on the outside temperature and the speed at which you are driving. However, studies have shown that using the AC can increase gas consumption by anywhere from 5% to 20%.
Rolling Down the Windows
Rolling down the windows does not require any additional energy from the engine, so it will always use less gas than using the AC. However, rolling down the windows can also create drag, which can reduce the car's fuel efficiency. At higher speeds, the drag created by open windows can actually offset the savings in gas consumption.
The Verdict
In general, rolling down the windows will use less gas than using the AC, especially at low speeds. However, if you are driving at highway speeds, the drag created by open windows can negate the savings.
