Not a perfect measure, but a good indication of cleanness through the air of the base models can be derived from the coefficient of drag and frontal area figures:

Model	Cd	Area m^2	CdA
G20 3-Series	0.23	2.22	0.51
Q50	0.26	N/K	N/K
Civic FK8	0.26	N/K	N/K
Civic FK2	0.27	N/K	N/K
A-Class	0.28	2.2	0.62
Avensis	0.28	N/K	N/K
VW CC	0.3	N/K	N/K
A4	0.31	2.2	0.68
Giulietta	0.31	N/K	N/K
F20 1-Series	0.32	2.14	0.68
