I must have done this wrong then. I have tried quite a few times though. I think template wisdom would suggest reaching up to the template to get lower drag.

They must have separated flow all the way down the back.

"Aerohead, I think you mentioned something about the tumblehome playing a large part in keeping flow attached once the rear glass goes out of the curve of the template." Flow is 3d, there are C-pillar vortices that can cause the flow to attach. However it is not always the result of C-pillar vortices, the EV1 had a lot of attached flow from the side of the car going over the back window. I would think that the XL1 is the same.
