Scuderia Ferrari SF15-T

[Pilatus]

Inch or less...
Just like height difference beetween them.


And that's the same car that they are drivin'... right?

From what i find on the internet the height difference between the two guys is just 1cm. BTW the seats are usually adjusted so that every driver's head is at the same height, unless the driver himself prefers otherwise

Yes, Seb is listed as 176 cm tall,
And Kimi is listed as 175 cm tall.

But it's obvious that height difference between two of them is more than 1 cm.
Somewhere around 2-3 cm.

Ferrari yesterday run 2 bodyworks. That i m 100%.


Only major difference between this 2 is shape of engine cover around exhaoust exit. The "tight" solution is conceptually exact the same like lastyears "Canada" spec.

Could be more differences that i missed.

Sadly i write this from phone so i coudnt post the pictures to support my claims.

Looking at the picture i think there are some misunderstandings...

I can't see any major differences between Vettel's day1 and day2 car.... but anyway this doesn't have anything to do with the last year canada's "tigher package" as F14-T AND SF15-T cant be compared because of a totally different Pod shape (more general undercut on the whole line... as the f14-t got the external part almost vertical) and a more inclined Pod exit on the new car

Here are some proof pictures:

Yeah you had probably right. I go throw all yeasterdays pictures, It was my mistake. i was pretty sure that it is indeed the change (2nd pic). What i could say, i m sorry. Angle and "blur-ish" 2nd picture deceive my eyes.

Overall height is only one factor involved in fitting a driver in a car. People can be the same height, but have different upper body and lower body dimensions - for instance SEB might have shorter legs but a longer torso, which means he sits higher in the car, but the pedals are moved closer to him.

I try listen all videos of "FIST" Ferrari (SF15-T) and think they less use wastegate like from last year. Especially under braking in and in transition points when driver hits throttle pedal. Torque delivery seems to be now released in much more controllable manner. Last year they also very offten cut or damp the torque spikes in order to make PU more drivable, ecpecially on Rai car that was the case.

Look back all yt "Vettel Ferrari Jerez" videos

and compare with that form lastyear:

or that with Alonso

https://www.youtube.com/watch?v=bS0qdcl665U

But just in this video below from on day three Ferrari with Kimmi unlike Vet use much more aggressive mapping and use wastegate overblow even more often. Especially into 2 tight corners entries (+1 traction spike correction). Probably last years engine maps?

Could also that be different mapping how to "harwest" 4Mj (or less than that) in 1 single lap . Maybe they tried evenly distribute the Regen modes during lap in order provide much stronger "off-throttle" blowing effect into low tight corners with very low entry speeds.

But for conclusion we need a lot more test days and to be sure wait for Melbourne Qually and race modes.

Anyway Ferrari did some pretty obvious chassis and PU changes.

Also there are reasonable amount of options how to ply with all ERS option and energy flow combinations. So could we expect even more different videos.

i dont agree with your analysis at all.and i'm not buying into your ability to tell how long a wastegate is open or closed based on average video from different cameras on different days in different locations on a track
Kimi was out on medium tires in damp conditions while everyone else was on intermediates... not exactly the conditions anyone would turn an engine up in.
i saw the "twitchy incident" from another camera angle... i think it was during a sky commentary video...
kimi hit the brakes at the chicane and the car slid in the direction of the gravel then he caught it and continued on... had nothing to do with power delivery.. misjudged his braking point based on the conditions just like he did on the previous lap when he locked the front right.

Ferrari using Flo-Vis on the FW neutral section, pylons, suspension back to sidepod inlets today.

Thats the F14t in that video, not the sf15t. Look at the nose. Thats why you heard the wastegate more often.

[MadMatt]

Sorry Pilatos, how can you compare the height of someone on A picture, and even more on THAT picture where we don't see the whole person?

They can have different shoes, can not be fully extended. Also variations during the day can be different from people to people, etc.

Please let's be a bit smarter/scientific than the usual crap people write about pictures and parts on this forum too often.

[MarkedOne8]

MadMatt is right. I know for my self that height during the day is soo different that it's barely believable. It varies as much as 3 centimeters during some days. I couldn't believe my self but I made measurements and it's fascinating.
Though I remember when Kimi came back to Ferrari that in the first couple of test days he had a little bit higher seating position. It was the same with Lotus. I think it's usual that some (every?) drivers start with higher seat fitting positions then later to add fine tunnings, etc.

[zioture]

[danielk]

All of this sparked by different seating positions for the driver maybe one persons torso is bigger than the other? Posture is Different? One has a bigger ass than the other? Or maybe they just like sitting at different heights?

[poolboy67]

or vettel just simply wants to sit higher. can we just be done with this?

Or maybe they're driving with different helmet brands and both helmets are completely different (Arai vs Bell - The Arai has a slighty bulkier top, in comparison to the Bell)

[Crabbia]

Vettel and his engineers would have the telemetry from riakkonen's runs, definitely at this stage. If he saw there was the slightest difference in top speed or engine power, he, with the help of his engineers would find a way to sit lower in the car.

Lets put this one to bed along with the shrink wrapped engine cover that never was.

Except that sometimes you are ready to compromise performance if you feel better in the car in X or Y position, so performance is not always the number 1 factor. But yea, let's move on.
