The Silhouette is not that bad.. except, again, the hatchback rear config... It could also benefit from a Kammback or boattail with some pretty extreme benefits...

When GM says the Cd is .30, they're not giving you the proper figure... what's the actual frontal area of your nearly 7 foot tall van? When you figure that in, you're not getting that great of a deal.

Swapping a Metro/Swift 3 cylinder into that van could be relatively easy though, just as Honda guys have swapped anything and everything they could into their cars...

With enough work, even the D15Z1 could fit into it.. although it would have to be mounted "backwards" of the original GM design, since Honda engines spin backwards.
