I can see that the lower outwash portion of the sidepod is pretty longer than on F1-75, also with bigger undercut.
This part was extensively discussed here by Vanja#66 and Andy76 and and Alberto Aimar on youtube channel, regarding the drag generated by the sidepod in this area. If I remember Vanja#66 find some stagnation in air flow in the very beginning of the vertical part of the sidepod on his CFD analyses.
Also I think that rear rod on upper triangle of front suspension is linked on the nose lower than earlier, similar to RB and Alfa.
