I noticed the Ford Focus wasn't on the list.
The figures for the 2000 MY aka the First generation were well reported. Ford advertised them as:
Frontal Area(est): 21.97 sq.ft.
Frontal Area(est): 21.97 sq.ft
Frontal Area(est): 22.24 sq.ft.
For the "second generation" 2008-2011. The sedan and coupe had the same frontal area and cD.
Second gen Focus 2008+
Frontal Area(est): 22.8 sq.ft.
The 3rd generation 2012+ I couldn't find an official cD for a specific model but I calculated the frontal area incase someone finds it.
Frontal Area(est): 24.17 sq.ft
Source: The older generations are on Cars.com or any other generic car info site. I got the 2012 cD from Ford media
which doesn't specify which body style.
