    Provisionally looks like Bottas needs an other new engine. During the last race there seem to have been many engine related problems (Steering wheel warnings and radio messages)

    I'm not up to date with rules and technical things but can't RB "simply" copy the MB flex suspension? I realise it is not as easy as that but would it be legal?

    Nope. Not that easy.

    Legalities / timeframes / tokens / high-rake v low-rake etc, etc.

    Basically impossible without designing an almost new car.

    Yeah on reflection it would be a mammoth task! I couldn't listen to the video at work so only watched the pictures (kinda enjoy having a job to go to ). I suppose it's more than just that little bit of flexible stuff near the back wheel.

    I have seen some of these technical discussions on the rear wing and Merc speed. One what I have not seen is what is the impact of the rear dropping on the ACTUAL open gap in the rear wing. When the rear drops the opening effective area may change. If somebody has seen discussion on this point please post.

    Dropping the rear on a stiff F1 suspension is minimal, but then every fraction of a percent helps in this game. Offhand, I would not have thought that this would be enough of an advantage. But then, F1 is the cutting edge of technology, and much of the developments here eventually translate into production vehicles.

    The aerodynamists in F1 are top notch. When I was still working at Atlas Aircraft, one of these in the design sector came from McLaren, very talented and knowledgeable.

    I only saw talk on the dropping of the rear suspension stalling the rear wing, thus reducing it's drag resulting in more speed. No confirmation and how this actually works (in relation to the bigger gap, if any) Thing is, until it can be seen in action, it is a shot in the dark. Redbull is trying to get a "free protest" by trying to create "noise" around what they think is the cause is, and getting the FIA to investigate. This often happens in racing when the aggrieved party is not 100% sure of their case in terms of putting in an official protest.

    Drop of the rear suspension is removing the "vacuum" under the car and not stalling the rear wing (as I understand). To explain what I mean: Think of vertical blinds. You can adjust the angle they are set at BUT bending the knees you get bigger or smaller gap to see through without changing the setting of the blinds. That drop of the rear changes the angle of the rear wing compared to the direction of the car travelling. Wind resistance is speed squared, e.g. speed^2. Area is squared 1. Reduce the resistance area and having the engine power constant results in big benefit on straight line speed.

    How that removal of the "vacuum" under the car impact the speed I am still trying to understand in full. I will get there. (I am mechanical/metallurgical engineer and not aerodynamics)

    All of this is a force balance. Engine is giving force forward and wind plus what ever is backwards. Force is a vector and that means vector maths. In corners there are force vectors in 3 dimensions. On straights only in two. (Excluding 4th and what ever dimensions we do not know)

    Best explanation by far.I just think the vacuum bit is thrown in to distract everybody from the actual facts.

    I like to think of drs like those part horns. Where you blow it makes a noise and opens up the rolled up tube. The harder you blow the wider it gets until maximum and with full effect. If you do not blow hard enough you get very little effect.

    Could it be that with the drop the wing now points slightly upwards which then allows the air flow(majority of it) to go over and under with very little going through the center. So when drs is open, the load over the top and under wing changes and increases through the center. That mass force of air could of been the problem with failed wing.
