And if you do a lot of highway driving, you'll get better MPG by using the AC versus opening windows because of the reduced wind resistence.

Perhaps not if you just pop the moonroof (tilt up) if so equipped, and maybe also open the side windows a crack.

What would you say is the break even speed for windows down versus using A/C?

That's something that will change with every car, but it seems like I've heard anywhere from 50 MPH to 65 MPH. Above that, use the A/C.

I would hazard to say that was not the case with any car I have had.

Why do you say that?

Because every car I have had has gotten better gas mileage with the windows down and the A/C off than the windows up with the A/C on.

So you've actually calculated your highway MPG with and without windows open and with and without the AC on. What was the difference in MPGs based on your calculations?

I have friends who live in downstate IL (I live near Chicago) so going to see them I usually drive most of the trip on the Interstate. Usually going there in the heat of the day I would drive with the A/C on but coming home well after dark I would drive with the windows open in the cool of the night. At times I would test this theory by filling it up at each end and checking the mileage. IIRC it was slightly more than 1 MPG difference.
Now my dad lived out of state (about 450 miles away) and I had a car that if I drove windows open I could make the trip in one tankfull. But with the A/C on I would have to stop for gas maybe 10-15 miles sooner.

This comparison between Honda Fit & Hyundai Accent was pretty good. I only read the latter parts of the thread & didn't see any comparisons of the MPG of both cars.
My wife's 2008 Accent, bought in Dec 2007 gave 30 to 32 thru the winter & rose just a bit as the weather warmed. I was a bit disappointed, thinking a Honda Fit might have given better MPG.
Finally, I got to take the Accent on 3 day trips to the mountains & Mt. Rainier, getting 41.5, 42.6, & 45.1 MPG! Suddenly, I didn't think the Fit could have gotten any better MPG.
