It does raise one other question though - if this is true, why doesn't the FIA publish this kind of information. Clearly the teams are told, but for some reason they keep the fans in the dark.

To put that wing movement into perspective, look at the (minimal) joint between the neutral part and of the main plane and the wing pillars:

The leading edge of the wing (central section) is moving roughly twice as much as the camera housings, hence the wing is pivoting around the joint.

Honestly it seems like everything is flexing big time, starting from the nose cone itself.
They showed lots of cars over those curbs, none of them flex like that.

I don't think it's due to fixation point of the wing, a lot of teams fixate their wings like that now.

I think only the nosecone flexes, the wing seems to move more but the flex seems bigger because it's more noticable there. (more lines, pivoting effect etc. optical illusion)

I'm convinced they use something dead simple to make it flex.

Excatly...they showed lots of cars and none of other car wings flex like that. Flexible wings are not allowed but theres no rule of nose as i know, so flexible nose put wings close to the ground as possible.

the writing was on the wall since 2009 when RedBull officially admitted in interviews they actively research flex induced aero gains by using multphysics simulations tied to composite layup software..
They have a wealth of experience with this now and we will see even more insane force response in the future.

Last week in India, the slow mo shots of the Ferrari showed the same type of things. Instead of the wing tips bouncing up and down relative to the center section, the entire wing was pitching up and down relative to the chassis.

Is this a possible way to get around the tests, build the main plane stiff enough to pass the tests, but allow the mounting to rotate?

[Bomber_Pilot]

I have absolutely no doubt that this wing passes all the scrutineering, just like the wings from any other team. The problem is, that RB are years in front of the FIA, considering this flexi matter ( or it is just something simple like the mounting of the fw, that allows the flex, since I think that the nose with the FW aren't attached to the car during scrutineering) You can see how in sync the nose and wing flex frequencies are... In any case a beautiful piece of engineering

Odd to get rid of the second feeder hole under the ramp.

[munudeges]

A ferrari insider (user fabioc) has posted on an italian forum (blogf1.it) that one of the elements of rbr performance is a special dispensation from fia which allows renault powerd cars, officially for reliability issues, to move coolant liquid between different reservoirs, thus optimising weight distribution. merc and ferrrari not allowed to do that, even if they have already asked for it.

This is probably the FIA's idea of 'equalisation', which was all supposed to be about equalising power and working from there. The engines all now seem to be unequal in a lot of areas. Engine homologation is just a joke.

I think the flexing nosecone and wing pilon mounting are no coincidence. I think they may have the nose cone flex in low-med speeds increasing overall AoA to the entire front wing. Asspeed increases the added downforce at the rearmost section starts to push down on the back of the wing compared to the front. This in turn flexes the wing to reduce AoA. The only legal way to have the pilons flex that much would be to have them barely holding the wing on, which is best done by that silly mounting.

Why do I say this? I had suggested about it in the rb7 thread midpoint last year.

[Kiril Varbanov]

Looks like VET has complained about his braking pedal application and the brake calipers, initially located horizontally at the bottom of the drum, had to be changed/moved.
The has been observed back in 2010, Suzuka, when Newey decided to go for horizontally mounter calipers, they were problematic in terms of reliability, though, so they had to revert to more classical position. All in the name of lower center of gravity, the bleeding, however, was a problem.

Update: VET's gearbox has been changed (prior to the 5 race cycle), as well as selected gearbox ratios, therefore pitlane start.

The clarification request about rbr multiple oil tanks is now official. I think this supports trusting fabioc of blogf1.it as a reliable source.

[raymondu999]

Which multiple tank story is this shelly? Got a link?
