Mercedes-AMG F1 W10 EQ Power+

Sure looks like >5mm change.

I wonder if they could make the suspension much more compliant at extreme turning angles. Result when tested while stationary < 5 mm of ride height drop, but while moving, downforce pushes the front down more than that 5mm.

A really stupid question - but why red?

Paying homage to his red hat that he always wore, I assume anyway. The Halo is kind of like a hat on the car, I figured it was for that.

Look at any picture of Niki that you can find on the internet, see what he's wearing.

Ah ok, yeah good point about the hat.

'Old photo' (what's called old... . They've got an improved version now/already/again.
Actually historically Ferrari enabled this solution but is not using it...

Mercedes' front Suspension Analysis

Slow turns were the weakest aspect in the Mercedes W9 and specially the W8, their long wheelbase (longest of the grid) was a problem in slow tracks like Monaco, as their pressure center moves backwards a lot as speed decreases, generating understeer due to the loss of front downforce.

Before the start of the 2018 season, FIA introduced a new technical regulation (after Ferrari's suggestion) that limited the hight variation of the floor (front) with the variation of the direction angle. Therefore since 2018, a suspension system called "Pushrod on Upright" is legal.

Ferrari tested this system later on during the 2018 season, but isn't using it this year. However, Mercedes noticed that this system was perfect to solve their slow turn problems in 2019.

In the video, you can see how the W10 moves down significantly when the turning angle is at its maximum in the Monaco hairpin.

Can't really find the source of the 'tech' who quoted this.

I am missing something... the uprights are fixed at the upper/lower wishbones. How does putting a knuckle in the steering linkage change the axis of rotation? Is the steering linkage also doing some of the function as the push/pull rod?

I mounted a short video, any idea on this weird behaviour?

Looks questionable. I'm not a fan of banning items that pass scrutineering however.

I wouldn't say it's weird behavior, at all. Each team has unique suspension geometry and they all make setup adjustments to cope with Monaco's requirements. Merc also have very unique high upper wishbone setups on their front suspensions. To me, this seems like an obvious case of something (e.g., the anti-roll bar in action) appearing more visually dramatic than it actually appears.

Me too, however in the recent past we have seen several cases of technical checks successfully passed (blade on the Ferrari's floor, endplates of RB front wing) followed by the obligation of a corrective because some elements exceeded in movement despite the respected static limits.
We are talking about suspension, but the aerodynamic effect is pretty evident.

It seems related to steering angle. Isn't that caused by the caster angle?

Sorry for my ignorance but I still don't understand how this mechanism (as clever as it seems) equates to better performance on slow corners?

The suspension seems to rise the moment the steering wheel passes 180 degrees. Does 'castor angle' also refer to how the pushrod is mounted or is it just about the steering angle?

Regardless, because of this pivot, as the wheel turns the castor angle will change. When the front of the tire turns towards the chassis the pivot will move rearwards, bringing the pushrod into a more vertical position. Maybe the car can manipulate the suspension droop at the extreme ends of this steering input?

This mechanism lowers the front of the car through slow corners. When the front end drops closer to the track the front wing will produce more downforce due to the ground effect from the bottom of the front wing. It is sort of like a mini diffusor at the front of the car. This added front downforce will move the aerodynamic center of pressure slightly forwards, increasing oversteer. F1 cars are normally set up in such a way that they understeer at low speeds thus increasing the oversteer characteristics of the car will help it rotate through short radius turns. Also, it appears that this mechanism helps increase the contact patch of the tire on the track, increasing front end grip further.

At least that what I think is going on!
