I can't find HCH II's Cd & FA. If it's better than megane's one then very little can affect the aerodynamic.

From
Automobile drag coefficient - Wikipedia, the free encyclopedia and many other pages, HCH's Cd is 0.27. Not found the Frontal Area, the smallest CdA shown in this page for a Honda Civic is 7.04. With a Cd of 0.27, this is a FA of 26.1 ft² = 2.42 m². This is a lot so it must be a previous Honda Civic with a Cd of 0.31, which corresponds to a FA of 22.7 ft² = 2.11m², closer to my megane's FA of 1.99m².
Whatever the FA, a Cd of 0.27 for such a little difference with my
megane which has a Cd of 0.32 is astonishing to me.
