No need for the resident mad scientist to make an experiment on this.
The way that device works is it create micro vortices (mini tornadoes) which aid in the separation of the air from the sides of the truck into it's slipstream. Also, this creates a "pocket" of air behind the truck which helps reduce air drag. Without the device, the streamlined air could "cling" along the sides and around the back of the truck creating more drag.
This is similar to the principal of a certain soviet advanced fighter jet's wing design, why it could achieve extreme maneuvers and such.

I've been thinking of making a couple for myself, actually, as I regularly drive at speeds of above 60 km/h (most experimenters say there's not much in it below this speed). If it does, like some suggest, tame car motions in crosswinds, it'd help me on my reguar... uhhhmmm... high velocity tests...
3M Command strips, with a cheap small plastic thing attached? Hmmmm...

The original topic was about wings and spoilers improving economy, and the answer is "yes", but only if your car was properly designed to make good use of the wing, like the lancer Evo 8 and 9.

March 3rd, 2007 12:34 PM #25anything you put on your car that doesnt add to performance only adds to weight. thereby only increases fuel consumption. Serious studies always show that a rear spoiler only has minor "help" to handling and economy - only at speeds of 160kph. If you always drive below this speed, the rear spoiler only acts as an "extra weight" to your car and oesnt contribute to any performance at all..
peace!

sinabi moh! i hardly see my children now. when they were young, schedules were more predictable.
Traffic!
