After finding this and reading through, I wish he had stuck around. Formula SAE experience is better than what I have access to. But the follow up data didn't really happen, which is disappointing.
Back to the notorious audi photo, Mercedes is doing much of the same, so I think they're on to something.
While it doesn't look useful in the center, and may just be hiding attachment points, there's a clear pattern at the skirts, and they cared enough to extend the dimple from the pan to the side skirt. It looks like they're trying to generate vortices that fence underbody and outside airflow. A pretty cool alternative to low ground clearance. I've looked for CFD or other photos to confirm, but it would seem Mercedes likes to hang on to what they learn in their multi-million dollar testing facilities. Go figure. Thoughts?
