Fuel economy and air conditioning

August 13, 2009

I know summer is sadly coming to a close for many of us, but let’s face it, the weather hasn’t exactly been typically warm this year. However, the next few days (in western

Pennsylvania, at least) promise to bring us some more seasonably hot weather.

I tend to be anti-air conditioning. I’m always cold.  Unless it’s very hot, I usually prefer to drive with the windows down. Then I end up wondering if I’m being more or less fuel efficient.

It’s fairly common knowledge that using your car’s air conditioner zaps your fuel efficiency. However, I’ve also heard that driving with your windows down creates more drag on your car that can also reduce your fuel efficiency.

I came upon this Slate article this morning that gives the rundown of how using the AC versus driving with your windows down can affect your vehicle’s fuel economy. It’s worth a quick read if you’re interested.

Of course, if it’s a 95 degree day, my guess is that you — and me, too! — will care more about not melting into the seat than fuel economy and will most likely turn on the air.
