Standard weight distribution from 2011

Post here all non technical related topics about Formula One. This includes race results, discussions, testing analysis etc. TV coverage and other personal questions should be in Off topic chat.

Re: standard weight distribution from 2011

There is one very good thing for a "standard weight distribution", which was hinted at by the earlier posts; -heavier driver's will not be penalised as there is no room for weight distribution optimisation using ballast if you're driver is light weight...

A standard weight distribution simply shifts the design responsibility from the car designer over to the tyre designer.. to design their tyres in accordance with the car's weight distribution, rather than designing the car's weight distribution to suite the tyres....

....You could say its a good way of reducing costs for the teams too... as they no longer have to conduct testing to determine the optimum weight distribution...

.. Havnig said all that it could all get a bit messy as the team's will need to make sure that the distribution doesn't change as the fuel load changes....

I think atleast they want the relative behaviour between the front and rears similar.

what sort of figure is it now , something like 40/60 ?

at least we won't have the position from a few years ago , where michelin biased the tyres towards the rear [ just right for the renault ] , and bridgestone towards the front [ firmly planted front end for michael ]

equal chance for all if this happens , level playing field

Has anyone seen a clarification of this?

It is not a standard weight distribution by rule, I thought it was a specification of weight distribution, for the benefit of tyre suppliers to aim their constructions at, and for car designers, knowing what the tyres are being designed to, designing their cars in accordance.

If someone wanted an alternate distribution, then there is nothing to stop them.

So that's what I am wondering, is it a rule that cars will be scrutineered to, or is it an agreed serving suggestion, a sensible way to help kickstart tyre and car designs for next year, with the clock ticking and all that.

I found an article in AMuS about this issue. The German text is in italics. I have added my translation.
AMuS wrote:Teams bauen Autos nach festgelegtem Reifenmodell

Die Teams sind trotz der Ungewissheit noch ziemlich gelassen. Sie können an den neuen Autos bauen auch ohne zu wissen, wer im nächsten Jahr die Reifen bereitstellt. "Wir haben ein Modell von dem Reifen erstellt, den wir uns nächstes Jahr wünschen. Auf dieser Basis bauen wir unsere Autos", erklärt Ross Brawn. Dieses Modell betrifft die Karkasse, deren Aufbau den Fahrwerkstechnikern wichtige Hinweise für ihr Aufhängungskonzept und die Gewichtsverteilung gibt.

Brawn weiter: "Mit diesem Reifenmodell können wir auf Werten aufbauen, die uns bekannt sind. Im ersten Jahr mit einem neuen Hersteller wollen wir nicht in wichtigen Eckpunkten wie der Gewichtsverteilung überrascht werden." Eine Unbekannte bleibt aber laut Brawn: die Reifenmischung. Michelin hat angeboten, dass die Teams unter drei verschiedenen Reifentypen wählen können. Pirelli will die Wahl auf zwei Reifentypen beschränken.



Teams use common tyre model for car design

The teams are relatively confident despite the uncertainty (of the 2010 tyre supply). They can get on with next year's car design without knowing who will supply next year's tyres. Ross Brawn: "We have defined a (data) model of the tyre we require next year. It will be a reference point of our car design." The model represents the properties of the tyre construction (carcass) which will give the vehicle dynamics engineers important reference values for the suspension concept and the weight distribution.

Brawn adds:"With this tyre model we can build on some known parameters. In the first year with a new tyre supplier we do not want any surprises for key parameters like the weight distribution." According to Brawn one unknown variable will remain, the compounds. Michelin has offered the teams a choice from three different compounds. Pirelli wants to reduce the choice to two dry tyre compounds.
This makes a bit more sense than a standard weight distribution. If the FOTA technical working group has agreed the tyre model between the teams and the suppliers they should be able to narrow down what they may get in the end. More importantly, they will all be off target by the same error if they all work to the same model. Of course this will only work if all teams are provided with the same information and communication by the eventual supplier. In the light of that approach it is clear why a non automotive top team like Red Bull is concerned with a supplier choice favored by Ferrari, Renault and McLaren. Some animals could be a bit more equal.
Formula One's fundamental ethos is about success coming to those with the most ingenious engineering and best .............................. organization, not to those with the biggest budget. (Dave Richards)

I like the 2 compound idea ...but would prefer free choice of tyre within that
maybe one stop using hard/hard , or 2 stops using soft/soft/soft ; would vary according to track AND driver

again easier for the smaller teams with more limited resources

Just read, fixed weight distribution for next year: 46:54+-0.5% so I hope that will solve some problems for MGPs car next year.

It is a pity that FIA have to help Merc get it right!

Um mit der Konstruktion der neuen Autos beginnen zu können, haben die Teams Pirelli einen Anforderungskatalog gegeben. Doch wie sich die Reifen am Ende tatsächlich verhalten werden, traut sich keiner wirklich zu sagen. Mit ein Grund, weshalb sich die Teams und die FIA zum ersten Mal in der Geschichte der Formel 1 auf eine fixe Gewichtsverteilung geeinigt haben - und zwar auf 46 zu 54 plus/minus ein halbes Prozent.
google English:

To begin the construction of the new cars can be, the teams Pirelli have given a set of requirements. But as the tire at the end are actually behave, nobody dares to say really. One of the reasons why have the teams and the FIA agreed for the first time in the history of Formula 1 to a fixed weight - at 46 to 54 plus / minus half a percent.

If they really have agreed to a fixed weight distribution then F1 is descending to Formula Ford levels. I wonder what Todt makes of it.

According to the homepage above its only for 2011, because of the new tyres to prevent misjudgments about the actual characteristics of the new Pirellis.
To avoid the situation like 2005 happened to Ferrari or this year to MGP.

In my opinion its a good idea, so no one will be screwed if they miscalculate the Pirelli tyres.

+1

And the plus or minus 0.5% each way is still a big enough gap in F1 I think.
Could also bring the pack together.
More could have been done.
