I don't believe that KIA/ Hyundai / Genesis reports complete drag coefficients.
There brochures report identical Cds across all optional equipment, which wouldn't occur in the real world.
And different tunnels produce different numbers.
I'd relegate the 'Drag Queen' values to some special case They're not cross-wind averaged, as would be the case for the maker's coefficients.
I suspect that we'll never obtain all the data we'd like for the CLA.
We 'fully' discussed the CLA here at the AERO Forum nine years ago.
