Ok, this is all pulled out of my arse, and probably equally useful as what normally comes out of there, but here goes:
There's been some discussion about whether or not the new Ferrari is zero-keel. It is. A keel would dip down and disrupt the airflow under the nose and clearly this image shows that while the chassis dips down for the lower wishbone to connect to it, it doesn't dip down enough to be called a 'keel'. Hence it is definitely zero keel
(see image below):
The next thing I noticed is the absence of the winglets right above the upper wishbone. I believe they are still there, but cleverly disguised as the thick part of the upper-wishbone. In the pic below, note the area circled. The green arrows denote airflow from the newly-angled back edge of the front wing. The air will be directed up into the suspension/winglet:
I have a theory that one
of the winglet's uses is to increase straight-line speed by inducing lift onto the nose at high speeds (such as on straights) to counter-act the downforce created by the front wing (to some degree). Because of the small size of the winglets, the aerodynamic effect on them (lift) would diminish faster than the downforce of the larger front wing would diminish at lower speeds, thereby preserving the downforce for cornering. This next image goes a little way towards that thought:
In the image you can see that the upper-wishbone area is not symmetrical; the top is more rounded than the bottom (this airfoil configuration would generate lift). At the very least, Ferrari are using their suspension as aerodynamic parts. Also note the little winglet on the connecting end of the pushrod.
(all images were lightened up in Photoshop for clarity)
EDIT: In case anyone thinks I'm actually serious, I'm not really. About 20% serious because I can't figure out any reason why those winglets should generate lift, as they obviously do, but the rest of the theory is just wacky. I sometimes need a wacky theory or two to shake up the 'ole braincells. Most likely they are for cleaning up the air close to the c#ckpit, as both the c#ckpit-end wishbone and push-rod are wings.
