I don't understand the virtual long tail? Is this a bit like that morelli tail thing?
I believe the way the T50 works is the diffuser is stalled without the fan (too steep), so that if the fan is sucking the boundary layer away, the diffuser produces both lower drag and more downforce. The car sits high enough that you can send quite a bit of air under the car without creating too much drag.

On F1 cars, I think the car is set up to pull a lot of air quickly under the car to produce high downforce at the expense of drag (ground effect is probably the main contributor). Stalling the diffuser reduces the airflow through the bottom of the car, and cuts both drag and downforce.
