You should have enough information now, to estimate the IONIQ's mpg @ 80-mph with Cd 0.20, or any Cd for that matter.
You won't have to speculate.
The material from Coventry University's aero mods of the Audi A2 ought to be adequate to get you to Cd 0.20.
Technically, your IONIQ's Cd is already as low as Kamm's lowest K-car that he drove in Germany.
Four wheel skirts would likely be sufficient for Cd 0.20. ( AeroCivic, Ford Probe-V, Ford Probe-IV, Porsche 60K10, Railton Mobil Special, Volkhart V2 Sagitta, MG EX 181, VW-Drop, VW-Flow, VW-Blunt, GM Aero 2000, GM Aero 2002, Solar Team Eindhoven Stella VIE, etc. )
