front wishbones are done and adapted to the chassis and spindle assembly. i’ll probably go with pullrods and hidden springs and dampers more pics below

Caddy is trying something different, they got pullrods

@MercedesAMGF1BR Changing to front pullrods won't magically give you more performance (in terms of raw lap times). However, it will help you maintain performance for longer and more consistently, especially in real racing conditions (heat, traffic, long stints, etc.).

ed Bull has built a reputation as the most innovative Formula 1 team over the past 20 years. Adrian Newey regularly caused amazement at car unveilings. Has the star designer’s departure also taken away the team’s innovative spirit? When Red Bull completed a filming day on Tuesday and released the first images of the RB21, many still believed it was a fake. Red Bull Unveils: 2025 Formula 1 Car at Bahrain Shakedown When the RB21 rolled out of the garage on Wednesday morning at the opening test of the 2025 Formula 1 season in Bahrain, there was indeed amazement again – but for a different reason. In fact, the Bulls hadn’t intended to mislead with their initial images: the RB21 looks almost exactly like its predecessor, the RB20. No other team showed so few obvious changes over the winter. Red Bull: Evolution or Stagnation? Particularly curious: after Red Bull dominated the 2023 Formula 1 season, the RB20 wasn’t just a slight evolution of the outstanding RB19 but an extremely aggressive development. After a challenging 2024 season finale, Red Bull emerges from the winter break with an almost identical car. “In this rules cycle, it’s clear that the cars have converged and look very, very similar,” defends team principal Christian Horner. Indeed, many Formula 1 cars of the 2025 generation look very alike, with concepts having aligned. The differences are sometimes only noticeable with a magnifying glass. In the fourth year of the current regulations, teams are now only chasing thousandths, not tenths. The New Formula 1 Cars of 2025 on Track: Pictures of All 10 Teams “It’s inevitable that there will only be marginal improvements,” Horner says. But the Brit also makes clear: “Every shape on our car has changed. It only looks so similar because it follows a similar philosophy.” Indeed, there were bigger changes under the hood with the cooling system. The suspension was also revised. However, the changes are marginal because Red Bull has been using pullrods at the front and pushrods at the rear since 2022. Accordingly, only minor improvements were made there. Ferrari, on the other hand, only switched to this setup at the front axle this year. It remains questionable whether a larger package will arrive by the Barcelona test. Horner denies it: “This will fundamentally be the car we start the season with, maybe with minor changes until then.” However, word in the paddock suggests that a bigger update could come as early as Friday, the last of the three test days in Bahrain. The fact that the RB21 looks confusingly similar to its predecessor doesn’t necessarily have to be a bad thing. McLaren, the strongest car at the end of the past season, wasn’t fundamentally different from Red Bull. The crux isn’t in the basic concept but in the many details. That’s why Red Bull draws a positive conclusion after the first test day. “The car feels good,” reports motorsport boss Dr. Helmut Marko from the garage. “It reacts logically to changes above all. We also had a very good long run.” Neither was a given last year. Especially in race trim, the RB20’s weaknesses often became apparent. “At the moment, we don’t have to fear anyone,” Marko says.

(2/10)Pour y arriver : Modification mécanique principale : nouvelles suspensions avant, qui restent des pushrods (contrairement à Ferrari, ils n'ont pas cédé aux pullrods que RedBull et McLaren possèdent depuis.... 2022 !! Ils seront donc les seuls du top 4 avec pushrods avant)

Open wheel suspension mounts the dampers longitudinal (well mostly) in the nose. The motion is converted via pushrod or pullrods and rockers. In the case of Indycar they are pushrods Item 13 in the photo below

#F1Testing Surprise : Williams reste aux pullrods arrière, malgré le travail qui a été effectué sur l'arrière de la W15 (boîte, etc) pour adopter des pushrod. Lors de la présentation de l'Aston AMR24, Fallows avait choisi les mots : "nous avons hérité (les pushrod) de Mercedes"

(14/33) Mais en 2016, Ferrari repasse aux pushrod. Simone Resta invoque notamment un gain de masse (pullrod sont lourds). Avec les pullrods,les composantes internes sont placées en bas du châssis, ce qui les rend également moins accessibles pour un changement de réglages rapide

On va s'occuper du réglage de la suspension. Pour ce faire on va adapter la pression des pneus, la hauteur de caisse en ajustant la longueur des barres push/pullrods. (La suite arrive après)

(17/25)L'intégration entre éléments mécaniques et aéro revient en fil rouge durant sa carrière : chez Fittipaldi, McL, ou RBR où il réintroduit les pullrods à l'arrière en 2009 (que tout le monde copiera). Devinez les seules pièces qu'il a dessinées sur la RB18? Les suspensions !

Ce qui est très étrange, c’est que Red Bull arrive à avoir une très bonne tenue pneumatique. Or certaines équipes ont refusé d’installer des pullrods car les efforts sont théoriquement plus importants sur les pneus avec cette suspension et favorise la surchauffe.

La différence entre des suspensions à poussoirs et à tirants se fait sur la position du culbuteur et de l’amortisseur. Sur les pushrods, le culbuteur est en haut, donc la barre pousse lorsque la roue remonte, sur les pullrods, il est en bas, donc la barre tire.

The uprights are extended vertically to permit a high mounting point for the upper wishbones. The lower links are parallel with the driveshafts. The pullrods pass over the outer exhaust, and under the inner exhaust, to activate vertical spring/damper units.

They alter the length of the pushrod/pullrods. There are different shims to allow the height to be altered. Teams will run different heights front to rear.

Thanks. Makes sense, since their pullrods/rockers have been raised and placed more rearwards, very close to driveshaft in 2022, their roll bar had to go elsewhere and hang a bit higher : )

Alonso's DRS is kaputt and out of order today according to AMuS. The pullrods are barely visible here.

For @ScarbsTech RB18 Pullrods

Les suspensions sont des pushrods. J’ai pas l’info de savoir si c’est la version définitive des suspensions, mais c’est notoire. On pensait que les équipes partiraient sur des pullrods qui semblaient être la solution la plus efficace en terme de balance et d’aéro (en théorie)

(5/N) Vous voulez savoir pourquoi Newey avait décidé de passer aux pullrods à l'arrière ? Il l'explique lui-même dans son livre "How to build a car" que je vous recommande (c'est facile maintenant avec le numérique). En photo, 2 images pour vous donner un début d'explications

(4/N) L'arrière de la #MCL36 est TRÈS intéressante. Ils ont innové non seulement avec pullrods à l'avant (mais ça on s'y attendait) mais en plus avec pushrods à l'arrière ! Newey avait lancé la mode des pullrods à l'arrière, et tout le monde avait suivi pour des raisons aéro
