Either way, 0.31 is still a good number. By contrest, the Ferrari 599 has a drag coefficient of around 0.345-ish, and the stock Nissan 350Z is 0.30.

I think it's the European spoiler anyway, even though I can't find a direct confirmation now. Someone mentioned that the lip spoiler is required in Europe for efficiency reasons. Also, if you look at the Civic Hybrid and the Accord Hybrid, they both add these lip spoilers to decrease drag. I don't think that they would add any spoilers to those cars to make them look cooler or actually increase the drag.
