One day on the freeway a Civic Hybrid passed me in my LX Civic. We were both the latest bodystyle, 06-08. I noticed that it looked slightly different, though. Now I checked Honda's website, and they have two photos from the same angle of a non-hybrid (it's the EX but whatever) and the hybrid.

The differences are the antenna and something on the very back of the trunk. I am wondering if anyone can identify if/why these features are aerodynamically superior, and if either of those ideas could be applied to my Civic. Thanks!
