If so, that's 1982 technology, Pontiac Division of General Motors applied to their next generation Firebird Trans Am. Something like a 4-count drag reduction.
Cardboard and duct tape would tell you what they'd do for you on the IONIQ.
I did it to Spindletop, SPIRIT, and Baby.
The belly pan runs flush to their bottom. All the way around the vehicle, including the diffuser.
I'm surprised Hyundai hasn't done that already.

I doubt I could see any aero difference when testing the super small side skirts though, even doing the cardboard and duct tape thing I doubt I’d be able to measure any difference. The after market side skirts seem like it doesn’t hurt or improve aero and are just for looks, as long as you don’t have them sticking out super far
I’m currently playing around with cardboard to figure out a good length and shape for my rear diffuser where they rear wheel spats blend into it before I pull the plug and by a huge abs plastic sheet to make the permanent diffuser.
