It looks pretty good. I'd radius the horizontal edges because otherwise the smooth wake your working for will be disrupted in the last foot. It might anyway, that notch is big enough for recirculation.
The forward facing fins are called Vortex traps on semi-trailers (lower right).
You might put clear plastic vortex traps in the taillight cutout, now that I think about it. Are you going to have turn signal repeaters?

Yep, turn and brake in the base plate. I'm going to try and work on it more tomorrow, and just radius all the front edges.
Vortex traps in the taillight cutouts is a good idea, and I just happen to have a big piece of acrylic that I could chop up....

Happy too help. I like the idea too.
You'd get more refraction with a curved piece.

Fixing some mistakes and gaps:
An aluminum panel will cover the underside once it's on the cargo carrier.
And, the almost-finished mockup, with tail lights, license plate and light, solar panel, and lid with flush hinges:

Thanks!
1 layer of 6 oz twill and one of 8.5 oz weave, angled 45-degrees to each other; paint of some kind, although I haven't decided what yet.

Maybe already answered, but what is your solution to being able to get into the hatch? How easy is it to get to the hitch?

I have the box sitting back just far enough to clear the hatch opening, which also gives me enough space to stand between and load things in back.

The fiberglassing is coming along, but nothing picture-worthy yet, and I'll be tied up most of this week with no time to work on it. However, one minor aeromod completed this afternoon: redesigned front wheel air dams.
Actually, these are version 2.0; version 1.0 I made entirely out of aluminum, extending 20mm below the stock air dams. However, after getting a chance to test them in the freak 4" of snow this weekend, it turns out aluminum is too rigid to use for this--they were getting bent and pulled away from the wheel well liner.
So, 2.0 uses heavy interior/exterior rubber mat I happened to find at the hardware store. The dams extend 40mm past the stock dams, to 65mm above ground. I modeled them on the Cadillac CT6 plug-in dams:
Large, two-piece for flexibility, made of heavy rubber, and wrapping around the forward part of the well.
I'll see if I can get some better pictures with the car on the ground when the weather's a little nicer.

The tail is done!
Well, mostly done--there are still a few odds and ends left to take care of, like wiring in the solar panel and charge controller and adding some side bracing. But, the majority of the work is done and the car is driveable (after being out of commission while I waited for a day warm enough to paint and then install the lights), just in time for the Green Grand Prix!
I ended up painting it with bedliner. Black+thick covers a multitude of sins; this stuff is UV resistant, abrasion resistant, and impact resistant, so it should hold up well.
I still have to attach the aluminum closeout panels on the bottom; then it will have a smooth underside.
Some other details. Rear wheel fairings:
Front wheel air dams:

Woohoo. Glad to hear you got it finished up.
Do you have plans to test its effectiveness?
