>As for studies, yes they have been done, I do not have a subscription to pull the numbers: https://arc.aiaa.org/doi/abs/10.2514/6.2014-2013 https://arc.aiaa.org/doi/abs/10.2514/6.2014-2013 Ok, so you have no numbers, you just pasted here the first thing that showed up on Google without even being able to read it, just to cover your ass, while a sibling comment provides numbers from Mercedes that show the gains from door handles are negligible.
