In the top left the steeper slope leaves the smallest wake , with the below depiction showing a diagram with a fairly steeply sloped back on it.


Which makes me think the Boxfish *may* be made less steep to accommodate the passenger seating more then being a perfect angle, it may be a compromise, as with the audi A2 slope, I am thinking.

Could be the steeper angle is actually better ? here is a good example of what I am referring to as "perhaps" the better slope.

The SolarWind looks very close to my Beetles shape, I wonder if it's profile is the more efficient one ..?

on a side note:
I just ordered a anemometer gauge better know as a wind meter , for small scale wind tunnel test so I can test with accurate wind speeds.
