Sauber: The slotted 2009 rear wing made a reappearance, the inlet in the mainplane expands inside the wing to a full width slot
Sauber introduced a number of developments Late in the Jerez test.
These include the blown rear wing based on the 2009 design, new turning vanes some cockpit fins and cooling outlets.
The rear wing uses the moulded inlet on the front of the mainplane to feed a full width slot exiting behind the wing, just below the slot created between the main plane and flap. This is similar to the wing used at Monaco in 2009.

Meanwhile the cockpit gained a pair of serated fins placed where the mirrors would normally be placed. These sit inside a wedge shape space ahead of the sidepods that allow bodywork. they send a vortex over the fronts of the sidepods, although it cannot be ascertained if this goes into the sidepod inlet or over the top of the sidepod.

Then just by the side of the cockpit on the sidepods are two new cooling outlets. unlike other teams Sauber choose to fully expose the vents, so they sit proud of the sidepods top. Other teams have these joined to the cockpit side. Cooling outlets in this area are allowed as they sit just inboard of the controlled sidepods surface. additional cooling is provided by long thin louvered panel (not visible in these pics) moulded the floor in the narrow coke bottle area. Again this sits below the controlled area for the sidepods surface.
Under the raised chassis at the frotn fo the car are a pair of new turning vanes, not especially clear in the photo, they curve down and outwards, just behind the wishbones.

Love the technical insights in your blog. I would appreciate if you drew arrows to indicate what you are talking about to help those who aren’t as knowledgeable in f1 engineering as others.
Great article, thanks!
