Hi All,

The Prius, like other cars these days have the wheel well liners, so the engine bay flow is probably not the issue.

The Prius does have the stock wind deflectors in front of all the wheels. Which limits direct flow of air that hits the tires, and gets drawn by the Magnus effect up into the well, and expelled on the down wind side of the wheel well.

Still, on the rear wheels especially, one can see the out-flow dirt streakes from 2/3 s the way up the well on down.

Ooops, I got this Magnus effect thing wrong. Its just plain pressure flow up into the wheel well. The Tires are running in the wrong direction for the Magnus effect.
