MORE TWEAKING AT THE REAR
When Mercedes is using a high-downforce setup, the rear wing’s main plane is no longer curved but flat (compare yellow outline).
Elsewhere, the floor has been tweaked in at least two areas: the ends of the diffuser have been strengthened (lower picture), while an element has been added ahead of the rear tyre, in the area where the floor is cut to fend off tyre squirt, namely the dirty wake of the rotating wheels (see white arrows in the middle image)
