actually, the wing will only make the dust worse. due to air's circulative properties, it tends to form a bubble behind closed areas or really anything in the trailing end of the object. the wing closes off a space which will then gather a lower pressure and circulate more air just simply due to vehicle speed and air pressure differentiation.

if you want to blame something for all the dust, blame the wagon
it's large & broad rear end acts as a giant aerodynamic drag bubble, hence which is why the wagon gets slightly worse mpg than the sedan, despite weight (although that does make a minor diff.).

 

Thanks but I still want to get rid of the dust

you seem very brilliant in this field, got a solution? Huge ugly mud flap covering the entire are behind the rear wheels?

Hose + sponge.

There's no good way to keep it clean with zero effort, though applying Rain-X to the window should help.

 

But if you still want a wing here's one http://www.tmtuning.com/HOME/catalog/product_detail.php?default_product=1605

 

He means something like this,

Never seen one for a Passat, just fullsize vans/wagons from the 70's

Where are our skandinavian gravel road driving members? oke:

 

hmm. that actually could do quite the trick to reduce the drag bubble, slightly increase the mpg possibly, as well as divert the air coming at the car downward.
worth a try. sure beats doing nothing at all!
i want to see results from that!

 

That's it, where can I get one?

Any assistance in this matter would really be appreciated.

 

If you look at the H2O pics..there was a gold wagon parked next to me that had a rear wing that I think had a cut out in it. So it looked like a roof spoiler and acted like the ebay one.

 

Very new to the site, where would I find such pictures????

 

search 'h2o pics' in titles only noob! oke:


7 pics down :thumbup:

I have a Zender lip on the top of my wagon hatch and agree it helps trap even more dirt than before (which was a lot even then).

But I did see a wing, of sorts, posted on someone's wagon here, that attached at the outer edges of the hatch and held a wing rearward, leaving about 1-2cm gap between the trailing edge of the hatch and the leading edge of the wing.

I'm no aerodynamicist, but that seems to be the best way to burst the bubble behind the car while having minimal impact on fuel economy cuz it's not catching air, just splitting the air rushing over the roof, which would break the aero bubble created by the wagon shape.

 

Nahh, just that travelling on gravel roads may have resulted in a local solution, like those giant light bars we see on the front.
