Ferrari 2017 Contender Speculation Thread

[bhall II]

Matematically the ratio of power/drag decrases with speed. So power has a more pronounced effect of the accelaration at lower speeds. So it is more valuable to sump power at lower speeds

I have no idea how you can read what you've cited and draw that conclusion.

I'll leave it for someone else to explain, because I'm simply not the right guy. But there's no shortage of people around here who are more than capable.

That shark fin looks exactly like the one in the unborn Manor, so the real one (if there's one, that is) will look nothing like it

I am conflicted if there is going to be one. They have not used since 2011. However back in 2008 regulations provided a somewhat similar wing (low and wide), and back then this was a very common sight up and down the field.

*Which explains the early lack of stiffness?

Picture something kinda sorta like this...

Then imagine what might happen if an insufficiently stiff gearbox case squeezes a turbine housing--containing turbine blades spinning at 50,000rpm--that's not quite strong enough...

Lets return the favour. Why do you think your idea is more likely than ERS management?
And do you think it is realistic that Ferrari design, test and validate a gearbox that is so floppy that it negetivly affects top speed on the straight? In that case, what about corners? Ferrari weren't that bad in China, and could (should?) have had pole position.

I'm with me4me on this one. ERS management seems much more plausible scenario.

The general consensus is that most, if not all, of the 2017 cars will have one

I agree this seems most likely.

If we assume the power unit, ICE + MGU-K, makes 640 kw and the vast majority of that goes in aero drag then at 330 kph ;

turning off the ES to MGU-K feed might drop power to around 580kw and speed to 320 kph

Turning off the MGU-K altogether might drop power to 520 and speed to 310.

No need to flex a gearbox or invoke any other malady. It's just what you do to optimise energy over the lap.

[bhall II]

Saving something in the neighborhood of 54kW over 200m doesn't sound like a very rewarding strategy.

EDIT: Or maybe it is, since it would only cost a few hundredths. Either way, that is a quality rebuttal. So, good on henry! =D>



Note: The highlighted variables were left at their default values, because I have no idea what they are for a F1 car. The others are reasonable estimates.

Of course there was also this:



If the rear of the car was intended to dip under certain forces, and the gearbox was intended to be the element that deformed under said forces, presumably that's something that - until perfectly honed (which perhaps Ferrari never managed) - can also deform at other times and in untended ways (since it's intentionally less than totally 'rigid').

Sorry if doublepost, but according to this Italian article, Simone Resta wanted a switch back to pull rod at the front... . Ferrari got both pull and push rod architectures ready for the front suspension... and they finally decided to use the push one. Pull rod on the back of the car got some attachment point modifications. . Confirmed gearbox and PU components redesign

push-rod rear. really?

I read the pull-rod (tirante) will be (more) horizontal....

here from 2015 to 2016 (less horizontal):

Looking at those pictures it looks indeed like SF-16H rear suspension might have suffer from installation stifness problems. Thing is though, I bet it is quite hard to measure statically, while heat and vibration may affect stiffness of the materials quite a lot, and also, there is always a compromise between stiffness, weight and aero requirements and it is not a trivial task to arrive at the optimum. Which itself might be a moving target.

FrukostScones You are right im sorry ... i would edit my old post if you dont mind... it was just a miss-read / type error
What i wanted to say is that ferrari got ready both pull and push rod architectures for the front suspension... and they finally decided to use the push one. Pull rod on the back of the car got some attachment point modifications.

How should i do in this cases... call some mods action?

I edited your previous post. Let me know if you want to be different or added something.

Incidently, I would not be completely surprised if we were to see rear push rod at some cars. The diffuser got bigger, which might mean some suspension components are going to be in the way. Either this components will keep their pull rod layout and just be moved upwards to create space, or a push rod layout will be used instead.
