I understand pitch sensitivity. I'm just trying to understand what's causing it in the F2012.

Exactly, if one takes his/her palm out of a car window while travelling at speed, e.g. 80km/h and keep it straight horizontal, and then try to change the angle of attack, slightly up and down, will feel the forces from the slight change of attack.
Ferrari nose looks too sharp, straight, thin and horizontal, hence too sensitive to slight changes of angle of attach. Other teams have better airfoil shapes for the front nose.

The shape of that nose is beginning to annoy me, has that goulish thing ever seen the inside of a windtunnel in search for less resistance, it looks more like it was penciled to make sure the entire car would be travelling through turbulence at speed?

Can you elaborate on that? What is your explanation for that?

You're not going to get a good explanation of that on this board. It'll be a subtle aero effect that the team will struggle to fully figure out and correct.

Are my eyes playing tricks or are they running very little rake here?

Nope no tricks, very little rake. In Jerez they were running quite a bit, but since then it's been next to nothing.

i think that thats good..not bad..because when they get their exhaust working...they will be able to add rake so they will gain more performance and close the gap easier....their diffuser leaks now when they run it with rake....

It's never quite as simple as that. The car needs to be designed for a given amount of rake, so either they're currently running all the aero on that car at an angle of attack they weren't designed and optimised for, or they're going to have to redesign much more of the car when they are ready with the exhausts.

Don't know which drivers car, fuel load, new or used, or how many laps, but here's a shot of the rear tyre in FP2. Seems like maybe the team found a decent setup. Their long stint/heavy fuel race sim times were quite competitive. Alonso's that is.

i agree with u..what i meant is that the car was probably designed around rake with the launch exhasut position...but since they couldnt make it work they had to remove some rake because the diffuser was leaking...so a lot of performance was removed..

That's a Hard Compound.

If they have eaten Hard compound than i would say...they are hopeless.

Yes. They didn't run the car with reduced rake until it was clear that the original exhaust configuration did not work as intended.

My guess is that the reduced rake is an attempt to reclaim at least some measure of the downforce the exhaust was intended to create. F2012's pitch sensitivity, like you said, could very well be the result of everything being run at angles for which they weren't designed.

EDIT: amouzouris beat me to it.

The Gazzetta is reporting the new updated version of the F2012 will ditch the fron pull rod suspension for push rod. It says Ferrari engineers believe it will make room for the Mercedes f-duct system. But if true it would make sense as the torsion bars, etc are at the bottom & would be in the way.

Xpensive will claim conspiracy but be happy nonetheless. Although it's just rumor. Not confirmed.

Gazzetta

"It appears that after
have dusted off the suspension
perfect pull-rod — the last
Minardi had been in
2001 — in Maranello are for
return to the classic push-rod,
disavowing the original project
the single-seater. The operation
would the makeover
the shell (and all crash
test), but would allow for engineering to
implement more effectively
passageway
to insert the F-duct, front wing"

Is that even possible with chassis homologation? just thinking about how much the mounting points for the springs/dampers will have to move, plus the opening for the rod will change position.

You can crash test a new chassis this year unlike previous years.
