The main link to this sight gives a very interesting road vehicle aerodyamics section. Thank you Google for the autotranslation feature!

Check out http://inter.action.free.fr/ Then hit the "Aero Lab" link, and follow by hitting the "Aerodyamics of Road Vehicles" link.

donee,I skipped this image,as it is a small scale model in a model wind-tunnel,and from the look of the smoke trace I'll bet a rubber donut that this was a very low Reynolds number environment and what we're seeing is not what it would be like in the real world.
If you reverse the image of the powder blue bug above it,you'll see that this photo comes from VW's full-scale tunnel and is above critical Reynolds number.
That site has some great images.
They stole my paste-up job of the Honda Insight range-extender trailer I created.My French is lousy but it looks like they're giving photo credit to Honda.What a laugh!
