I haven't done any serious A-B-A testing of course, but my limited experience (a few days of driving compared to a almost a year of eco-driving before that), and my theoretical in-my-head analysis, suggests that this won't add any drag to the vehicle.
If you compare the amount of air entrained by the vehicles passage, with the air exchanged through the openings, there will be an orders of magnitude difference.
