^ I must be picking up some stuff because for once i understood the whole thing.
Those fairings reminded me of the VW Xl1. I remember thinking the fairing were pretty long. I suppose the reason why the back of the rear fairing is shorter is space issues. They just extended the whole thing forward of the rear bumper.
Then thers the fairings of the Edison2 VLC. I see your point RedDevil. The rear fairing tapers toward the car at the end.
