Part of science and engineering is achieving reproducible results and reporting all tests. In this case, we may save folks from spending time trying to reduce rear window drag.

Vortex generators may be useful in other situations or more carefully designed for the specific area. But right now, rear roof mounted, vortex generators have no beneficial effect on our vehicles. Still, some good came out.

I have trustable methodology for aerodynamic effect measurements. I also have an as yet, undocumented bumper air block (a water noodle.) I'm thinking about repeating this test using the bumper block and see if I can quantify the effect. To the best of my knowledge, no one has done this, yet.
