IONIQ belly and skirts

Just for ----- and giggles, if the IONIQ reacted to underbody paneling at all like the Audi 100-III, the 'missing' panels and 'slow' diffuser might represent a delta-Cd 0.030.
If rear skirts returned a 1.89% delta Cd as they did for WS 12 Aero, Advantage West Midlands, UK, Audi test car, that would be another delta-Cd 0.005.
That would put the IONIQ in Cd 0.205 territory.
It wouldn't take much else to push it to the new Cd 0.20 target.
