Cool photo, thanks for that
Can one of you aero guys let me know exactly what that does please ?
This creates lift -negative downforce- and a bit of drag. So on its own this is not desirable. What that tells me is that the halo creates substantial issues, either with the airbox or with airflow attachment to the rear (or both), which you can remedy through using winglets like that.
What I think is happening, is that the frontal tube of the halo pushes airflow higher up, away from the airbox and bodywork around it. This will rob the airbox of air, which has its impact on the PU, and the rearwing of airflow. So they have to come up with a solution, even though all of this is not desirable.
