No idea! I haven't tested it, so for all I know it could be hurting MPG.
But I did something very similar to the Honda Fit I owned briefly last year, and immediately afterwards, I was able to get higher MPG (by a couple) than before I did the mods on a trip that I did regularly. (That still proves nothing - not at all scientific.)
Mark: no extra steps to OPENING the hatch, but I have swivel tabs the upper portion to secure the clear panels when I close the hatch. Re. the wheels: previously they had coroplast discs on them. I lost one so went the tape route.

I filled the tank a week or so ago. Forgot to update the fuel log until just now...
Went 824 km = 512 miles on 28.4 L = 7.5 gal (US).
68 MPG US = 3.5 L/100 km

Installed OEM cruise control, audio controls, and a head unit from a higher trim level on my 2017 ES CVT. Used MMCODINGWRITER to activate the cruise control.
Finally went and rescued it from the wrecker lot.

Wow - that took a little while to get released. That happened a few months ago.

I totally understand. Nobody should ever tell me they're "not in a hurry" either!
