: NO,, its not true.. it was proved on myth busters that you get better gas
: milage with the tail-gate up.. there was a college that did a drag test as
: well and found the same results.. tail-gate down = more vehicle drag.. more
: drag = less gas milage..

They also showed that driving with the Windows Down and the AC off
provides better MPG than with them up and the AC on.

Never investigated that one. But who gives a fluck. I don't want exhaust dirt and our 115 degree summers infecting my commute.

Wind tunnel tests with the tailgate up show that a slug of air sits in
the bed without much motion or air exchange. This causes any wind to
skim the surface of the slug that has a very low drag factor. Putting
the tailgate down causes the wind to come into contact with the bed's
sides and floor, along with the tailgate, a higher drag factor than
the slug of air has.

The firs time the "mythbusters" investigated this "myth," it was one of the
worst run experiments they ever did,. They drove two Expeditions in circles
on a short oval race track (1/4 mile?). They kept the speeds low (45 or 50)
becasue they were afraid of overheating the tires. They used two different
Expedition, neither one of which was broken in. In my opinion the results
were worthless. And I think the "Mythbuster" realized this, since they
re-invertigated the myth. The second invertigation was a little better,
although they still didn't drive as fast as I thought they should. The
second invertigation yielded more sensible results - at slow speeds you
achieve better gas mileage with the windows down and A/C off. At higher
speeds, windows up, A/C on was better. In the real world it is much more
complicated. I think we could all agree that windows up / AC off is the most
efficient method but leaving the car at home is even more fuel efficient.

A college study, which I can no longer find, found that the most
efficient truck was with a shell that was cab height but curved in the
back down to the top of the tailgate. It smoothed out the airflow
behind the truck according to their wind tunnel tests.

Yeah Mythbusters isn't the last authority on anything... I think they need to find a real job. As for gas mileage, if people want
to save some $ another option would be to drive at a reasonable speed on the freeways. I doubt if 85+ mph speeds are conducive to
good gas mileage....
