I’ve noticed that the back of Ioniq is pretty big when it comes to wake size versus a Prius prime and Tesla model 3 and obviously every other modern sedan

Build some mockups, get some yarn and tape, a manometer and tubing and pitot tube, and
start testing. People speculating here or waxing on about hypotheticals will tell you
nothing about whether wheel covers will reduce drag on your car, or differently shaped mirrors, or a spoiler extension at a certain angle, or whatever you want to know about, and how much. The only way to know is to build these things--cheap, out of cardboard or coroplast or plywood--and start measuring their effects. Only then will you know what they do and be able to plan what you want to make permanent and what isn't worth pursuing.
