Since the Insight arguably has better shape optimization, the difference is in detail optimization between the two vehicles.

Wheels are one factor. But there could be other reasons like: enging cooling optimization, ground clearance (Civic looks to be lower, and definitely has a lower front air dam), undertray panels, just to name a few...
