Without a doubt about this, the sidepod design used by Ferrari at 2017 had an affect design teams up and down the paddock, with at least three other teams fielding a similar way in 2018. But while the rest of the teams ponderously continued using their more conventional designs, Sauber functioned as aggressive as its budget would allow, splitting their sidepod inlet into 2, one at the more conventional position and one other mounted atop.

As part of the sweeping upgrade package the team revised not only the sidepods but also the aerodynamic surfaces ahead and round them. A new boomerang winglet (blue arrow) was hung from the face of the chassis, in order to guide the flow across the sidepods, while a new splitter extension, complete with five slots at the leading edge was then installed. This complimented the strakes which were installed on the floors edge, since the designers look to quell the noodle wake obtained by these and improve flow to the diffuser down stream.

You’ll note that the detail changes which were made (inset), with the debut of the slot to the inner flap.
