The belly pan did make the car ride much quieter though. Then I fabricated a partial camback and was surprised when my freeway mpg went from 41 to 47. I thought it was a fluke so i repeated driving a full tank on the highway driving normally and the result was 47 mpg each time. A fifteen % increase in mpg is nothing to sneeze at. At any rate modifying the back of the car is where you will get the most benefit from aero mods. If you could make the front of the car more bullet like you could gain probably as much of an increase.

Well the front of my Ioniq already looks like a bullet. Once I’m done with all the mods, I’ll probably nickname my car “ the black bullet” lol
