Does driving with your windows down really save more fuel than using your car’s air conditioner? 🚗💨
You’ve probably heard the advice before: turn off the AC, roll down the windows, and save gas. But there’s a catch — and it has a lot to do with how fast you’re driving.
In this video, we break down what actually happens to your car when you use the air conditioner versus driving with the windows open. We’ll look at how AC puts an additional load on a conventional engine, why open windows can increase aerodynamic drag, and why the better choice can change depending on your speed.
We’ll also take a quick look at the history of automotive air conditioning and explain why the old “windows down saves fuel” rule isn’t quite as simple as it sounds.
So, when you're driving around town, should you open the windows? And what about when you're cruising down the highway?
The answer might surprise you.
