It is so humid here in the mornings I use the wipers to clear the windshield and turn on the defrost. Once everything is cleared off the windows go down and the roof open for the 30 mi drive to work.

Car use less gas with the AC on then with the windows down if that why you do that.

i know i cant roll down my rear windows because the past two months the roof liner has been pulling off with the wind from them being down...and my AC doesnt work...it might if i get all the new parts out of the trunk and installed one of these days

MYTH BUSTED!

was on myth busters couple months ago... it only varied .1-.3 MPG on a full size SUV

I would have to say that years ago, that would have been true about the windows down wasting more gas...but the aerodynamics have certainly changed over the years. One time I heard a morning radio station guy "debating" with a caller about the tailgate on trucks...leaving it up or putting it down....which way gets you more gas mileage? The deejay was saying he had read it that it was better to leave them up because the shape of the trucks actually creates and air pocket (or something like that). The caller was very insistent that his 1985 pick up got better mileage w/the gate down. I finally couldn't take it anymore, called the station, and told them they were both right and why (aerodynamics of the newer trucks)....so....perhaps this is the same case...??

it may use more gas have the windows down and ac on but I like it.

In Florida... windows down is the way to go, but if my A/C was working, I can't say it wouldn't be on on those 90+ days

Now my man drives a Jeep & he has the A/C full blast with all the windows down
I don't get it.... the cold air is gone as soon it comes out the vents

As far as heat... I'm with the guy with the Sweatshirt in the back seat
it takes too long for the heat to make a difference & here you might only need it a month out of the year

but also on that show they didnt drop the tanks and clean them out and put a meterd amount in each.
One was on the bank of the track when they sucked it out the other was flat on the grass that rite there is enugh dif to make the test invalad and yes the windows do drag our cars down badly in the months i can cruse with the windows up on the wife'* se i can get 32 mines per galon up in the hills just playing around i'm lucky to see 26-27 with the windows down doing the same route

hrm... someone agrees with me. I have to say if I were to move to florida, I would be in shorts and a t-shirt every day of the year.

And you can feel the drag difference with windows up versus down. If I am on the highway going any decent speed I just have the sunroof open and the rears cracked an inch. Moves a good amount of air. And I don't use the AC cause I don't like the slight loss of power, not cause I am conserving gas. I like to have all my power just incase.

I drive to work with the sunroof open and the windows down. On the way home I turn on the a/c

I hate the leaves that fall on the car. If you don't pull them off in the morning there will be a nice imprint of it by the afternoon. I can deal with the heat differences.
