Ferrari rejected Red Bull-style F1 suspension switch for own “innovation”

As a part of a push by Red Bull’s rivals to shut in on the world champion squad, a deep evaluation has gone into the components that helped make final 12 months’s RB20 so robust.

One space of curiosity has been Red Bull’s suspension format, with its pull-rod entrance and push-rod rear suspension being considered as key parts in delivering each good experience and improved aerodynamic efficiency.

The pull-rod entrance helps clear up airflow across the entrance tyre, whereas a push-rod rear gives alternatives in narrowing the gearbox and altering the ground form to open up downforce-producing efficiency on the rear.

While Mercedes is anticipated to hitch the development of switching to a push-rod rear for its new W15, Ferrari has notably caught to the pull-rod format that it has used for the reason that begin of the brand new floor impact period.

Asked concerning the decision-making course of to stay with the pull-rod, Cardile mentioned: “We examined for a few years a push-rod suspension.

“In actuality, our rear suspension is a bit completely different when it comes to prime and decrease wishbone distribution in comparison with a Red Bull one, to say one crew.

“We recorded good aero outcomes transferring in the direction of this route and when transferring from pull-rod to push-rod, we did not measure a giant benefit to justify some compromise when it comes to weight or compliance.

“So from there, we evolved our suspension, keeping the same layout.”

Ferrari’s stance on the advantages of its pull-rod design is additional enhanced by the truth that it believes its rear suspension for the 2024 automotive is kind of modern in its design.

As a part of an effort to supply a shorter gearbox – the chassis is known to be 5cm longer whereas the automotive’s general size is identical – it has needed to cleverly reorientate its suspension configuration.

As the above particulars in the principle picture present, the pull-rod aspect has been moved fairly a bit additional ahead than final 12 months in what’s more likely to be an try to enhance compliance and improve anti-squat.

Its angle makes it rather more intently aligned with the entrance leg of the decrease wishbone, and set again from the entrance arm of the higher wishbone.



Speaking concerning the work that has gone on with the suspension, Cardile mentioned: “The most important variations in comparison with final 12 months’s automotive are on the rear, the place the inboard suspension is in another way positioned contained in the gearbox.

“It is also a different concept which, for us at least, has been an innovation because it’s a different way to manage the inboard suspension compared to what we did in the past.”

Cardile additionally emphasised that the crew was dedicated to its suspension format for the 12 months and was not contemplating every other possibility.
