Indeed, simply outlaw everything outside 250 mm from the car's centreline ahead of the front-wheel's such. Introduce a flat-bottom rule as long as the's a car too measure, but let them keep the rear-wing if they think they need it.

I am dissapointed by the proposed new FIA test. If the flexing of the FW is not linear, then the test should be non linear too. I mean they can again redesign the FW to whitstand the 100kg load, even so they are allowed to flex additional 10mm....I don't get the new rule's spirit here. They should test the FW with 100kg, but to allow the same 10mm flexing only, or they should test it with the max achievable ~200kg and allow 20mm. As was mentioned before, the FW can achieve around 200kg or more downforce level in high speed situations. So again they left a quite large 100kg margin to cheat. Not to mention that they didn't propose any other test that checks the wing for front (drag) related flexing. If I understand the current situation, it's not sure that the flexing wings are flexing just because of down-pointing force (downforce)....so again the FIA thinks only on short term as always.
What you think of this test? Are you dissapointed too, or it's just my paranoia ?

EDIT : I see now that others are worried by this too..sorry, I was away for a couple of days, didn't read all the stuff carefully.

kalinka - I’m not worried. I am curious about what is happening, and observing the test loopholes because the FIA only testing a single predefined point.

A key part of this sport is to design the car to the rules. No rule will be perfect, and the excitement in F1 is seeing how teams use the rules to get the fastest possible car. So no concern from me that RB appear to use the rules in a different way. In fact I think it is good to see different applications of the rules.

I disagree with your suggestion of tightening the deflection criteria. Because depth of the central section is tightly specified, a wing would need to be 8 times as stiff to achieve a twofold improvement in deflection – deflection of a beam is proportional to depth cubed. It would not be fair to impose that sort of increased benchmark on all teams, especially the new teams.

i don't think that at speed front wing can generate much more than 200 kilos of downforce.Stated that i think that the rb wing flexes much more than the 20mm allowed by the linear test, this will at least equalize the flexing allowed for everybody. Taking into account the drag and the aero moment as well, i rate it unlikely those can provide such a contribute to still allow the bending and pass such a test.Moreover, noone knows if they'll test the wing alone or the wing and the nosecone attached to the car...Anyway let's wait and see.

It was actually quoted in the press that the front wing generates up to 500Kg / 5000N of force, so the FIA test only covers a very small amount of load compared to what the wing will actually experience. Hence the room for cheating.

How can you guys consistently call it cheating. They passed the tests as much as every other team did. :roll:

Simple - the rules stipulate that the aero parts of the car must not move, and that includes flexing. There is a subsequent rule that spells out the test that the FIA will use to judge whether teams are in compliance, and that they reserve the right to change the test at their discretion.

Their test has proved inadequate as Red Bull's wing is clearly flexing way beyond that which would be reasonable. Red Bull are clearly running an intentionally illegal part, also known as cheating.

I think I was referring to the same quote, that I can't find now, but maybe one source is saying 500kg for the whole wing, other says 200kg for EACH SIDE of the Front wing, the remaining 50kg let's say goes to the center section....just thinking. But for me it sounds reasonable that a well aero-balanced F1 car can generate more than 1000kg of downforce. Let's say about 600kg for the rear, and 500kg for the front end.

Just found this :

Wikipedia > Such an extreme level of aerodynamic development means that an F1 car produces much more downforce than any other open-wheel formula; for example the Indycars produce downforce equal to their weight at 190 km/h (118 mph), while an F1 car achieves the same downforce:weight ratio of 1:1 at 125 to 130 km/h (78 to 81 mph), and at 190 km/h (118 mph) the ratio is 2:1.

So at about 200kph the total downforce must be about 1200kg, which means the front wing can reach 500kg easily...I think. So there is quite a big gap from FIA test to full front wing load.....

The rule stipulates that a specific aero part of a car may not flex more than a given amount. This amount is tested by specific load tests on the parts in question. Everything flexes, the legality is based on how much it flexes using the prescribed testing.

As of right now, the rules/tests since race 1 2010, their cars are legal. They passed. If the FIA chooses to now change the test they can...and if the Redbull front wing passes this test, it is still legal. Even if it does flex more than all the other whiny teams would like. If it fails in SPA, then the wing is declared illegal for SPA, not for all the previous races.

Redbull arent cheating. They passed all the tests, as they stood at that race. Either way, i think these rule revisions in the middle of the season are nonsene.

Exactly, this imo is no different to Brawn last year interpreting the rules to allow a Double Diffuser - It's simply clever engineering solutions being applied to maximise car performance and that is what F1 is all about!

The Rules also specify that diffusers should look like this:

Sorry, i have been not that precise in my thought.
Actually a f1 wing produces those levels of downforce at, say, 330kph, and i thought it reasonable for a classic wing alone to produce around 200kg at 200kph,speed trough a medium corner, hence my statement.
But your comments made me think that such advantage is not only exploited in the corners, but while braking as well.On the other hand, the nonlinear fashion in which the df on the flexable front wing likely behaves under braking makes it tricky for the driver to manage without wheel locking and stuff like that, and we all know that tyre management is a key factor this year.
So they maybe will stiffen the wing to pass the test,they'll loose something in the corners but the advantage under braking could remain.

Hmmmmm. Yes, it is definitely layup methods as the Swede says but it's not just the wing, which appears to flex when the car is in a corner and where the outside edge gets closer to the ground.

There has to be a secondary effect of the nose rising or lowering though and that picture above just adds fuel to the fire as to how they're achieving it. The front end seems to move perfectly in relation to the wing, suspension and tyre so there is something weird going on. Many in other teams seem to think that there is something mechanical going on to achieve that nose droop but that does look strange, and it's not just a shadow and light difference. Look right at the front. It does appear to move. We'd have to see an equivalent picture of a non-flexing McLaren or something as a control though to compare otherwise we don't know what we're looking at.

Anyway, it's another one of Adrian Newey's modus operandis and little tasks that he sets other people - get the car as close to the ground as possible in any way that you can. This resulted in active suspension at one time and now we have this. Fascinating.

If the load is 200kg each side and it is tested to 100kg, then that's 50% load. Seems a reasonable test load to me. The real issue is where the test is applied, not how much.

Nothing wierd. Its just a trick of the light. Look at the markings on the nose, the bull, the roundel with the number, the base of the antennae, the LG logo. They are all static. Still. Not moving.

I agree with richard here..but not for the nosecone...Is it possible their nosecone is bendy? could it be they deliberately designed it in a ways to allow for bending to occur ?

How about that one:

The nosecone crash structure has two windows to the side at the very front ,effectively consisting of a top and bottom plate .We have seen them modifying nosecone shape this anlast year ,so what we see on the race car is not the shape of the crash structure....this way they could again with clever laminate orientation comeup with a nosetip tilting action at certain loads (drag induced forces= rearward
facing forces)...
