Rumour: Ferrari discovered ‘trick’ suspension for 2022

The 2022 Formula 1 car by Ferrari will have a “surprising” (and more aggressive) front axle according to sources close to the team – Indeed paddock rumour has it from Abu Dhabi in December that at least two teams may have designed a loophole and it could well be in the suspension area of the 2022 F1 car design. 

Could we see another ‘Brawn GP’ situation this season? When a surprise design loophole gives a team a massive advantage in performance over the rest? Sources suggest that as the 2022 cars will have a rather different load distribution compared to the 2021 cars: that the front axle will produce less downforce compared to the past, balancing towards the levels generated by the rear aerodynamic elements.

 

However, according to the engineers, it will be the floor area (including the diffuser) that will make the real difference: the new underbody will be able to generate around 65% of the total aerodynamic load.

 

Ferrari 674: new (aggressive) nose and Pull-Rod configuration on the front suspension system
Due to the way the new Regulations have been written, the 2022 season will be a year of technical discontinuity. The teams have had the opportunity to consider a complete overhaul of the suspension configuration testing it both in the wind tunnel and their simulators.

Ferrari is no exception. The Italian team has been working on their “Project 674” for a while – as Mattia Binotto, Team Principal and responsible for the 2022 car development, has often said – and the engineers have had the chance to test out multiple (if not all) solutions using their allocated wind tunnel time.

Ferrari has adopted a more aggressive nose design on their Project 674 – certainly a more aggressive profile compared to that seen on the FIA dummy, which was reminiscent of the design of the F14T 2014 (pictured below).

According to what Formu1a.uno has learned, Maranello has confirmed their choice to adopt a Pull-Rod configuration on the front suspensions – in stark contrast with the push rod suspension geometry seen on the latest single-seaters.

It’s a decision largely dictated by aerodynamics: the Pull-Rod configuration allows the flow to be redirected towards the bottom of the car and straight into the cooling inlets, which should also be lower, all matched by a more compact rear end thanks to the cooling “gills” allowed by the new Regulations.

This is a macro suspension solution that we could see on other cars as well. Just a few days ago, McLaren took to social media to share some revealing pictures of their 2022 chassis; in the cockpit of the MCL36 one can clearly see attachments for a Pull-Rod suspension configuration.

 

 

Pull-Rod front suspension: lower barycenter and better load distribution
The Pull-Rod front suspension configuration is also an advantage in terms of weight distribution and balance due to the internal suspension elements being placed in a lower position, hence lowering the barycenter of the car itself.

The stress load on the new cars will be different in terms of pitch and roll, but this should be balanced out by a more efficient load distribution as well. The front suspensions will help from this point of view because they will lower the barycenter of the car, greatly influencing the behaviour of the car when going through a corner.

Back in 2012 Pat Fry had described the Pull-Rod front suspension configuration as “a bit of an aerodynamic advantage, but also an advantage in terms of weight distribution.”

There are some clear targets that the 2022 cars will need to meet, such as the above mentioned load distribution in slow speed sectors and an efficient shock absorption system. The front axle management will be particularly crucial in slow speed sectors, where the load will move “forward” and the cars will need to be able to take advantage of the curbs to gain precious lap time. On the contrary, at higher speeds – with the pressure naturally being pushed backwards – rear stability will become the biggest requirement in the new cars.

  1. Everyone will try to take advantage of loopholes, but MB can be expected to be ahead of the others.
    In the past, they have put in illegal elements and gotten away with it with the collusion of FIA. This
    time, smarting as they are from the loss of WDC in 2021, they will do ANYTHING to give their drivers
    an undue advantage. Then Hamilton can make the hollow claim from the rooftops that he IS the Goat.

    • An example of fake news.

      The only team to have been tripped up by their innovate “loop holes” was Red Bull, having to change their flexi-wing as a consequence. The media spin by Red Bull (“Mercedes are outrageously fast because they are cheating “) was never born out by the stopwatch. I don’t recall a single race were they were the fastest ( despite all the claims of illegal wings).

      It’s about time we stopped regurgitating this nonsense.

      What Merc did seem to have was incredible acceleration (at times) which suggests an ability to deploy power in a different way than most.
