FYI, drag coefficient (Cd) is independent of size (design constraints notwithstanding). The better minivans have drag coefficients of .30, eg: the original Pontiac Trans Sport / Chevy Lumina vans, Toyota Sienna.

But total drag is Cd times frontal area, and yours is smaller, so you may still be ahead.

Have you seen this thread?

I know you started this thread to talk about aero, but I'd have to say before I spent a moment or a penny on mods, I'd get instrumentation. The easiest & fastest gains will come by modding your driving style, and you need feedback to do that best. Your garage entry doesn't show any fuel economy instrumentation.
