As these cars still possess bargeboards of a sort, I’d say it’s those rather than the actual floor. I think they’re calling them end fences. There’s one to each side the underfloor intakes. The outer-most extent of them appears to be doubling-up as a vortex generator with assistance from the sidepod curvature on the inside and airstream on the outside. Lucky that! Don’t you think.
