Windows Down vs. AC: What’s better for Truck Efficiency?

In the summer, fuel prices rise right along with the mercury in your thermometer. Consequently, you want to ensure that you are getting the best possible fuel efficiency for your truck. While saving money is one priority, staying cool is another! You know that running the AC can use up fuel faster, but is driving with the windows down any better for your fuel efficiency? Trick Trucks is here to break down the pros and cons of each approach.

Driving with the windows down

Most people would guess that driving with the windows down would be a more fuel-efficient way to keep cool in your truck. And to a certain extent, they would be right. Rolling down the windows does not tax your engine the same way the air conditioning does, and so, theoretically, this improves your fuel efficiency. However, there are a few factors to take into consideration when you drive with the windows down. Your truck is designed to be as aerodynamic as possible in order to reduce drag. When you roll the windows down, this can make your truck less aerodynamic because the air no longer has a clean line to travel over. At higher speeds, the drag on your truck could increase so much that it actually decreases your fuel efficiency more so than if you were running the AC at that speed. Generally speaking, for highway driving or driving at speeds above 40 miles per hour, it is better to keep your windows rolled up.

Driving with the AC on

As we’ve established, when you are driving at higher speeds, it is actually better for your fuel efficiency if you forego the windows and use your AC instead. But that doesn’t change the fact that the AC does use up fuel in your truck. If you prefer to drive with the AC on, you should reserve that for times when you are driving over 40 miles per hour. For slower speeds or stop-and-go driving, it is more fuel efficient to turn off the AC and roll your windows down instead.

In order to optimize your truck’s fuel efficiency in the summer, you have to find a balance between using the AC and driving with your windows down. But so long as you know your speed, it is easy to determine which option is best at a given time.
