Age old?

Thought Mythbusters did that one long ago. Came up with it wasn't better
down but don't believe said it was worse down.

Sounds like it is publicity for GM. This was tested and proven a
couple of times over the years. While you are looking, the windows
down versus up and using the AC is pretty much a wash too.

Mythbusters tested this on two different episodes. The second episode
was motived by a lot of people writing in with questions and remarks
about the first.

Both episodes showed that tailgate-up gave better economy than tailgate
down.

But in the second episode, a test with a cargo net (with tailgate
removed) had the better fuel economy vs other configurations...

I don't care about the fuel economy but when there is a "How's My
Driving" sticker on the back of the pickup, tailgate down is the way
to get there sooner.....

I just read an article on this (sorry, don;'t recall where) and the
automakers comments were that the best economy is with them up. They
also said the worst thing to do is use a cargo net. I suppose there
will be some trucks that don't strictly follow that "rule" but
everything I've read that's at all recent, and that was done by
someone competent and actually in the business of making trucks, says
leave the gate up.

From what I"ve read, once you are over about 45 mph it's not a wash
but you are better off with the windows up and using the AC. So it's
going to depend on the driving profile.

I saw tests that determined the same thing at least a decade ago.

Depends a bit on the truck. How high is the cab in relation to the
top of the box? How long is the box? How deep is the box? What shape
is the cab roof? and how high is the truck from the ground? All can
affect the earodynamics. In MOST cases there is only a small
difference one way or other, but there are designs that will yeild a
bigger difference, either positive or negative.

And the difference MAY change with speed as well.

I figure it does not matter. If it is too hot or too colds the
windows are up. About 4 days a year I wish I had a convert able again,
but the other 361 days, I'm glad I don't.

It gets way too hot with the windows up since the A/C died. Of course, that only
happens a few days a year.

Dating myself here. I remember when AC was an expensive luxury in
cars. There was always one or two people that would drive with the
windows up so others would think they splurged and had AC in the car.

But back then, cars had wing windows (AKA 'butterfly windows'). If you
turned them out all way you had a hurricane in the car. :-)

And people had big, folding road maps to use as sunshades for the
big side windows if they chose.

Around here tailgate down will keep you from getting billed on our toll roads. The cameras are above the road looking down and they can't pick up a license plate if the tailgate is down.

Around here the cops are staked out at toll booths ready to pounce on
anyone who semi-innocently obscures a license plate to evade a toll.
The victim then gets to pay the toll along with a hefty fine.
