I have developed the attached chart showing total drag power (kW) vs speed (km/h) of the Ioniq EV.
The chart is based on EPA official publication of drag coefficients for the Ioniq EV.
EPA is using coefficients to the function y=Cx^2+Bx+A where y is the total drag force (resistance) in lbf and x is the speed in mph.
The target coefficients for the Ioniq EV as found by EPA (or submitted to EPA by Hyundai) are: Coef A=21.17(lbf) Coef B=0.19016(lbf/mph) and Coef C=0.015762(lbf/mph^2).
