This 10 second video from this YouTube link: http://www.youtube.com/watch?v=KG6A5ZBNPlM

visually displays the aerodynamic disadvantage of the 2009 Escape. Note the "unsmooth" current at the rear of the vehicle

2005 AWD Escape Hybrid
Best Interstate tank trip MPG 39.02 (scangauge II) for 402 miles on I-70, 10.3 gallons used over mostly flat terrain.

Best Interstate tank trip E30 MPG 34.6 for 271 miles along I-80 in Indiana and Ohio.

Best multiple road tank trip E30 MPG 36.2 for 202 miles in Southwestern Pa.

What does that really prove? That is not a real vehicle and is not even moving? It is a still photo digitalized to simulate air movement but there is nothing scientific to prove it is any less aerodynamic than any other SUV. If you want aerodynamic I think there a lot of better choices as opposed to an SUV, but that is just my opinion.

Flow Illustrator is a tool for demonstrating the concept of flow over different surfaces. Lots of fun for playing around, but it isn't intended as proof of anything.

Hey...thats my video lol Definately not an acurate display but fun to play with to get a general idea. I've been playing around with it to get a basic idea of what airtabs or an airfoil might do to the flow charateristics. Just goofing with it to learn a little about aerodynamics.
Wishing I could afford something like Exa PowerFlow but that kind of loot isnt chump change. Especially for someone who wants to play, not start a business.

but thats how wind tunnels work... The object stays stationary and you move the air. Wind tunnel simulators ALSO hold the object stationary and SIMULATE the air rushing by at speed...as far as aerodynamics are concerned its the same.

I can't verify the programmer did a good job of setting up the model but if they did it should be pretty accurate for airflow analysis EXECEPT for the fact that it is only 2D and therefore says nothing about how the air flows horizontally around the vehicle... which is pretty significant...

Clearly an SUV is a brick.... but some bricks are more "rounded" than others and will be better for MPG.
