You should have tried searching here for the "Drag Coefficient" it's here. I asked several months ago and kps had the number it's 0.35. The Civic hatch for 2002 was 0.36 (higher is worse). As a point of interest the Drag Coefficient for the 2005 Scion Xb is also 0.35.

Here's the link to that thread FYI https://www.fitfreak.net/forums/95202-post1.html.

As for the Hybrid Honda's if you mean the Insight it was in the low to mid 0.20's if I remember right, I don't recall the exact # off hand or where I found it when I was searching. But that's like comparing apples to oranges it's designed differently.

Any time you have a flat hatch or flat surface on the back it's going to create drag. That's just a fact of life.

I found some Drag Coefficients here The Mayfield Company Homepage - Honda Vehicle Drag Data.

 

I want mud flaps to owned the sport for 3 days and I really want them----in addition to cutting down some splatter they would be really beneficial in protecting the paint.

 

Please, Honda, would love to have mudguards to fit my '08 BOM Sport.
All other cars I've owned has had mudflaps. I like them not only for the aesthetics, but mainly for the increased paint protection and prevention of at least some of the road film and grime thrown up on the sides of the car in wet weather.
If there's any aftermarket type that could be used, I'd be open to it.

 

they really need to make them i just bought a 2009 sport and would like not to have crap on the side of my car so i dont have to wash it al the time
