Test: Windows open vs. closed

Yesterday i did a coastdown test with my 4dr Civic. I did 2 tests in each direction with all windows closed and the same test with front windows open thinking this would be worse on fuel economy because it acts as a parachute.

I used my android phone with Torque app to log the coastdown times so they are the most accurate you can get.

The result, exact same coastdown time with windows open or closed.
