driving with the window down (at 80kmphr+)

Yep

(I do have a Prius! What I don't have is something to tuck)

THAT's the THREAD!!!!!!!!!!

[bookrats]

There's a thread on PriusChat discussing the open window noise (I know, you newcomers must be sick to death of hearing us say that... )

Basically comes down to a side-effect of the aerodynamics of the car. This lead to a debate as to which would be more fuel-efficient -- driving with the windows down and the A/C off, or with the windows up and the A/C on.

(But then, all PriusChat threads end in "what gets the best MPG"...)

OK, [url=http://www.priuschat.com/forums/window-noise-vp14448.html]here's the thread. (Someday, the "search for subject title only" option will work, and God will take me up to heaven. :mrgreen

Thanks :-)

There was a story in the news here in Australia a while back that claimed it's more fuel efficient in nearly any car to use the air con over the open window, somehow thought I suspect it depends mostly on what speed your doing :-P

and don't get me started about smokers.. I swear, the next arrogant so-and-so that I see flicks a cigarette butt on the ground (within a car or no) is going to his his/her head twisted off by a 6"3 angry bastard. :cussing: :cussing: :cussing:

There was a Near Darwin Award in SF Bay Area recently. A smoker flipped his burning cig butt out the window and it blew back in and started a fire in his SUV. The Bastard saw it in time and got out with just singed hair. The car was a burned out hulk.

And concerning the pressure thing. We get the same thing in our Ford Escort as well. My husband doesn't notice it, but it drives me nuts. We were having a weird overheating problem on the way home on a car trip and drove from LA to San Jose with the A/C off and the windows down to keep the car happy. I put earphones on to keep from going crazy. But I was the passenger and didn't have to worry about hearing anything. I think I prefer A/C. 8)

The pressure thing is reduced if you have cross airflow; open another window on the other side of the car.

Dan, you beat me to it. At anything above about 40MPH in both of my cars, it's necessary to open a rear window when the front window is open. It seems to be a combination effect of the volume of the passenger compartment and an opening being at the front of that volume, alternately scooping and venting the air. It creates pressure changes that are indeed most unpleasant.

Opening a rear window helps, but I've found I need to be careful with how much I open the rear window with respect to the front(s); if I open the rear too much the problem comes back.

At freeway speeds I just try not to do this, but my daughters really like having the windows open a tad in back, so I end up experimenting more than I would otherwise choose as a result.

I have to lock the power windows since my daughter likes to open her window when we drive. Even at slow speeds, I find the effect very annoying.

I have noticed this on other cars as well, not just the Prius.
