Scuderia Ferrari SF71H

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Could be useful in controlling wheel spin.
Would that not be illegal?
I wouldn't think so as it is directly under the drivers control.
Yes it would:
5.5 Power unit torque demand :
5.5.1 The only means by which the driver may control acceleration torque to the driven wheels is
via a single foot (accelerator) pedal mounted inside the survival cell.
5.5.2 Designs which allow specific points along the accelerator pedal travel range to be identified by
the driver or assist him to hold a position are not permitted.
5.5.3 At any given engine speed the driver torque demand map must be monotonically increasing for an increase in accelerator pedal position.
5.5.4 At any given accelerator pedal position and above 4,000rpm, the driver torque demand map must not have a gradient of less than – (minus) 0.045Nm/rpm.

Ferrari car being looked at by the FIA.

more horse ---. Its an open formula with strict rules, and many enforced rules that were never rules in the first place...

Blowing engine maps are unacceptable? Too f#ck1ng bad.
If the original source of news for Marca is true, then this is to prevent wing-blowing before it escalates. Ferrari exhaust isn't positioned to help with this at all, so they were probably just testing this system and/or testing FIA itself. Again, if the original source of this news is credible in the first place.
And they call it a stall. A STALL!

I am not sure what is so strange with Ferrari's sound. They just open the wastegate on the way out of turns. You could clearly hear it in the Barcelona test.

Why would they open the wastegate when they're accelerating out of a corner? Unless it's to limit power at the wheels, which would be traction control.

A couple of reasons, perhaps they get enough energy in blowdown that they can open the gates and still harvest, or maybe it's to get a nice big push out of the corners.

I don't know i am not an expert. It's not only Ferrari, you can hear it here.

And here is the Ferrari one from this year Barcelona test.

You’re right, to me it sounds identical to other cars, opening in almost identical locations. At the moment it seems like a witch hunt. The presumption that they must be doing something illegal as they are performing well... a little unfair really.

Any chance it's related to this lever on the steering wheel?

Is it 'allowed' to alter brake balance from side to side?
When arguing with a fool, be sure the other person is not doing the same thing.

No, only front/rear

But I think it would be enough to have some change or offset possibility in a corner. During braking the aero balance shifts slightly front to back, so it would make sense to alter the brake balance while braking. Before accelerating the BB is well backwards to straighten the car.
This is also the only thing that would be totally ok with the rules. And we know from the blown diffusor time, that Vettel is well capable of playing with such toys while braking.

so many questions about a lever... Kimi doesn't have it, does his car performs worse than Vettel's?

Right, I’ve been thinking the same all along - if it was anything more than a driver preference, both cars would have it.
