Yeah I don't get what they can do to a RWD to make it worse off the line than a FWD, will look up what they've done...

Sorry, OT...

They've given the BMWs a mandatory longer first gear to reduce their acceleration off the line. I think it's shit to be honest, it's good that the different drivelines have advantages and disadvantages. Ho hum...

The FIA have officially declared that "Any system device or procedure, the purpose and/or effect of which is to change the set-up of the suspension, while the car is under parc ferme conditions will be deemed to contravene art 34.5* of the sporting regulations.", i.e. would be illegal. They have also rigorously checked over the Red-Bull, and confirm that there is nothing wrong with it.

So has anyone got any idea how the Red Bulls are doing it?

But are they actually doing anything at all?

Didn't someone mention different tyre pressures for qualifying etc?

But that would adversely affect grip.

It's a balance. At low fuel loads, with a setup for high fuel loads, the car will run too high. By lowering tyre pressure at those loads they'll get a dramatic increase in downforce counteracting the loss of grip. Brundle was saying that even a ride height reduction of 0.5mm can make a huge difference to downforce.

Low pressure in the tires would increase the tire roll and would affect stability in the hight speed corners and under heavy breaking. No the ride height is being affected by the suspension setup.

It's going down with less full in the car, when it should be going up. More fuel more weight etc.

If the car is bottoming out in qually without the fuel in it (as reported my many) then with the fuel in it should be pretty much on the floor full stop. And it's not.

They are doing something trick - and potentially naughty. I just don't think the other teams have figured it out yet. You can bet your ass though as soon as they have the protests will flood in.

Or it's very well hidden.

Remeber the Renault launch system that was hidden under 5 button presses and a sign saying beware of the jaguar. Or Ferraris wobbly front wing that moved outside the weight limit force of the rules. Of the floor plan of the ferrari that dipped at the edges to create a ground effect when moving at speed. Stuff goes on all the time that the FIA only find out about later.

Also the FIA may know what redbull are doing and have descided that it is perfectly legal. In which case they have no reason to say what they are up too. the rules just say "they can't affect ride height independantly once the cars go to Parc Ferme. So if it's affecting the ride height inversly when the fuel goes in, it's within the letter of the law. If not the spirit.

Ah I didn't realise they were able to run so low in quali. Interesting stuff.

Interesting stuff! I wonder if they've designed the suspension to exaggerate the pitching forward of the car as the fuel disappears, giving the wings more of an attack angle or something. No doubt that would have too much of an adverse affect on everything else though!

They still only have four left though right?

Just wondered if they're allowed to fix the broken ones and bring them back to life? though I doubt Alonso's from sunday would have much left of it.

Yes, to a point.

In short, you're allowed to tinker with bits but if, say, there's a giant hole in the side now (Very likely with Alonso's Malaysia engine) then no. So really it depends what they changed for, they could well be able to use at least 1 of them again.

I think that's the problem, they're marginal on cooling. The engine changes after Bahrain qualy where as a precaution and if they're still working can also be used in the practice. I assume the Bahrain engine is being saved for less stressful and cooler races, something like Monaco.
