Scuderia Ferrari F1-75 speculation thread

[Marty_Y]

I thought the weight of PU's is defined by the regulations and all manufacturers are already operating at this limit aren't they?

You thought correctly

I don't know if this is relevant to the conversation, but there's some information about the weight of the new cars in this article.

FIA increases minimum weight of new F1 cars for 2022 again
2022 F1 seasonPosted on

The latest technical regulations issued by the FIA have added another three kilograms to the legal minimum. It now stands at 795kg excluding fuel.
The minimum weight limit for cars built to F1’s incoming new rules has been repeatedly increased. The new rules were originally slated for introduction this year with the minimum weight limit set at 775kg. A further 20kg has been added since then.

Next year’s cars will be 43kg heavier than their predecessors. This will be F1’s largest year-on-year weight rise since the V6 hybrid turbo power units were introduced in 2014, when weights rose by 48kg. A separate minimum weight of 150kg is defined for power units, including at least 7kg for the MGU-K and 4kg for the MGU-H

Keep in Mind those are Livery speculations with a very rough outlook of a 2022 Car underneath it.

[Stu]

That is the same base vehicle as the McLaren one released over the weekend.

If, indeed PMI is out of the picture, Ferrari themselves have say in the livery design.
Fingers crossed for some pre-1996 Ferrari red!

I’ve seen rumours of pullrod front suspension for both McLaren and Ferrari so far next season. This is surprising as pullrod seemed a bit of a disaster for Ferrari last time they attempted this.

If it emerges as the predominant trend then there must be some benefit

Little more about pull-rod suspension..

According to what Formu1a.uno has learned, Maranello has confirmed their choice to adopt a Pull-Rod configuration on the front suspensions. 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.
...
Another (not less important) reason to adopt a Pull-Rod configuration is directly linked to the new cars being much stiffer, as well as heavier, but also to the new rims and the new 18″ inch Pirelli tyres with a reduced shoulder profile.
Ferrari 2022 Power Unit: the Fire Up
While the targets on the engine front have already been defined, Maranello is determined to make good use of all the time they have at their disposal for the development of their new ICE (Internal Combustion Engine) before its homologation.
According to our sources, we shall not see a fire up anytime soon – at least not a “real” one. It a couple of weeks we might see (and hear) the new Power Unit being fired up, albeit with some elements such as endothermic, turbocharger, MGU-H, fuel, oil and exhaust to be homologated only during the first race weekend.
This “step by step” approach is nothing new for Ferrari (we have seen it in past seasons), and the team is set to go out on track in Barcelona for the first week of Winter Testing (21-23 February) with a Power Unit that might still be upgraded.

The SF15T was designed with it and was a pretty decent car though.

Food for thought.
Perhaps we’re all looking at the pull rod design in a historical context.
As the cars will need a stable aero platform to seal the new underbody, are we actually mistaken to call what appears to be pull rod suspension, a pull rod suspension?
If the damper action is reversed, and the rebound valving is now the dominant force as was done in nascar to enable the car to be pulled to the ground and maintain a more consistent ride height on the banking, then what appears as a pull rod set up, is actually an inverted push rod set up?

[Jolle]

About pull rod suspension: it wouldn’t be the first time Ferrari brings back an old design idea but forgot that it didn’t work the first time..

Pull rod is been tried on numerous occasions since the raised nose designs but no one seems to get it to work in practice (theoretically there are less problems). Could be of course, with the new rim hight there is enough hight difference to make it work.
It would be a risk either way. If you don’t try it, and everyone else shows up with a working pull rod, you’ll be in a clear disadvantage because of the airflow to the floor. But… if it doesn’t work, well, got two drivers complaining that they can’t connect with the front.

No, because the damper is working against the spring, so it's still in tension, and still a pull rod.

If I understood rightly the ScalexF1's post, the damper will be pushing the knuckle up, so a pull rod layout over low frequency bumps, will be an "inverted push rod" while travelling over high frequency bumps, because the damper will be pushing the wheel up indeed.

Nevertheless, this can be accomplished with push or pull rod indistinctly, I think.

The rear suspension on most cars is pullrod. There is not a fundamental issue with it but one of packaging and aero.

If a team can derive a benefit from pullrod then I'm sure we'll see it.

[JPBD1990]

I was reading comments on Scarbs twitter post about McLaren seemingly having gone for pull rod front suspension too. People were speculating that the new larger, heavier rims, and the stiffer sidewall of the tyre, may mean more force will be transferred through the suspension itself, and thus more interaction with the suspension in general.

Perhaps that’ll offset the vague/understory issues felt previously with the larger, softer tyres which may not have generated enough force for a pull rod design to work up front

At the rear it work well, even better than push rod because of in hight between the pick up points. In fact, because of the low rear, push rod wouldn’t work. Even teams that have the pull rod moved as far forward as McLaren for instance, get into trouble with precision.

In general I think you can see a difference in the way teams make their compromises. Ferrari and McLaren seem to, historically, compromise suspension components for aero while a team like Mercedes works more with maximising suspension and develop aero around that.
