Notice all the true racing cues in the BMW link pics.
The air management is identical (in function) to F1, Indy, Even the Formula SCCA cars I used to build. The underside of that car is generating at least as much downforce as the top.
And note the exhaust does not enter that airstream, which would reduce the downforce. The only thing they could have done with the exhaust was to make it exit over a wing on the side, or around the rear outside edge, which would have lengthened the tunnel that the air from underneath the car was travelling in, as well as helped to pull it out through creation of two new channels.
Over 200 you could stick this thing to a wall, easily.
