Google sketchup

[shafe88]

I made a car in google sketchup 8 and wanted to know if their is a way to test the aerodynamics or if their is a plugin that lets you do this.

You need a much more specialized software than sketchup to do wind tunnel testing in software, past hobby level.

Just like hang-the-9 said.

And unfortunately I don't think you are going to be able to export that car design - at least not in one step into other 3D modeling tools that also support physics testing.
