I just Googled "tiny ute". Too easy. (I won't spoil it for anyone who wants to make a genuine effort.) . Funny, I'd heard of them before, but hadn't seen one.

So:
Rear skirts
Fill in front arch gap
Flat hubcaps
Smooth out fog light holes
Partial boat tail/kammback (rear area reduction)
Undertrays front and rear

I'd also add: air dam. May be more effective depending on how smooth you're able to get the underside, plus it's far easier to make/fit than undertrays.

Any guesses on what results I'll get in terms of drag reduction and fuel economy?

If you did all of that, my W.A.G. is 4-6% better economy at 90 km/h.
