So other than the new front wing and turning vanes I can't see any other outwardly visible changes. I haven't found a shot of the diffuser area yet to compare, but it looks like the aero work is concentrated at the front of the car. The rear wing appears identical to the last race.

Ferrari have a new floor and difuser in this GP......

Yes IIRC this is a completely a new thinking philosophy for FW in a part of Ferrari. Caz every other team are trying to send the air outside of wheel wake where Ferrari is trying to scoop some air inside the wheel. May be its directing air towards the Front wheel break disk. Or as a wild guess Ferrari might trying to replicate some of the Flex wing solution with this as car speed rise so does the air flow around the tyre. so with angled FW they will bend the tip of FW as well as the whole FW toward the ground. But the burning question is how they are mitigating the problem of drag in high speed. Think that F138's FW is designed with remembering this concept. As the high speed air started to create drag problem by lowering the FW towards ground, so Ferrai's FW must stall somehow to negate that effect.

Whatever the simplest answer is it might just create vortexes which leads the air toward the sidepod turning vent. which ever is correct Mr. Gary Aderson will not be happy with this caz last year he just criticized Ferrari for immature FW design regarding their FW endplate now Ferrari is not only continuing with them but bringing further conflicting concept.

Thanks X2 for the link.

It seems that my idea was not that far from Piola's interpretation. Still question is how F138 is stalling the FW in high speed Caz F138 is showing very good speed in all of the races so far in the speed trap.

Just read a comment on twitter from @f1_aero saying that ferrari triple element under nose barge board aim does create a cleaner vortex than a single leading edge. So that's probably the same aim for the e21 slotted bargeboard.

Back to ferrari fornt wing, they had a different philosophy last year also, placing small slotted inlets on the endplate side, where other teams (notably williams, for example) have big outlest. With inlets I mean guides for the flow to come from the outside to the inside of the wing - desing that could be helpful to mnake the inner part of the wing work better in yaw.

Now that i read the article on omnicorse, it seems similar, except they say that mclaren and redbull were doing the same last year whereas they wer doing the opposite (outlets on the endplate opposed to ferrari's inlets.
Any way it seem that omnicorse rely on a good source - f1 aerodynamicist; the idea that wing flexing helps with tyre vortex management is not new though, it has been talked from a year or so

It seems the first slot in the foot plate is helping to send some flow inward and below the wing while the rear slot is actually getting some flow from inside the FWEP.

7 Element FW is above & beyond the others as well. Interesting how they are working their FW

So other than the new front wing and turning vanes I can't see any other outwardly visible changes. I haven't found a shot of the diffuser area yet to compare, but it looks like the aero work is concentrated at the front of the car. The rear wing appears identical to the last race.

Piola reports the outer gurney flap has changed.

Translation of Piola's Article:

Ferrari has also changed the rear diffuser recovering of the concepts we had already seen on the F2012 last year in the second half of the season: the Gurney flap that "frames" the extractor now has a more rounded in the outer part, revealing also a greater inclination of the side wall.

The F138 in China is proving to be a machine that has recovered the downforce that seemed to be lacking and is especially noticeable in the exploitation of soft tires: Fernando Alonso managed to close the fastest lap in FP3 maintaining an excellent step in the third sector, where other machines are already in crisis.

hi guys. have someone noticed if the upgrades bring in china were used in qualifying ?

The front wing and turning vanes were used. However Alonso mentioned some of the parts they brought did not deliver. Not sure what those parts were, and they may not have been visible I.e. not bodywork.

it may have been "fix it again, tony" at times in the past, but this year's carbon fiber quality looks stunning to me! (I believe another poster also pointed this out previously.) thanks to all those posting the close up pictures.

Below is from Malasia, and I can't see any difference in the diffuser or Gurney. It clearly changed between rounds 1 and 2, but I'm not convenced it has changed again for China.

It is incredible how tiny modern gearboxes are!
