Actually, the hybrid style spoiler is functional for drag reduction. The "sporty" Civic sedan trim had a different, bigger and blingy-er style spoiler.

When Canada introduced a tax rebate for efficient cars around 2008 (since cancelled), the base 5-speed, non-hybrid Civic sedan originally fell just under the rebate threshold. So Honda revised the car to get it into rebate territory by adding the hybrid rear deck spoiler, hybrid wheels & tires (and a few other mods). There are a lot of Civic sedans running around here that look like the hybrid, but aren't.
