Ferrari SF23

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

It's this magic thing, called 'brakes'
Its before he brakes , its during acceleration listen to the revs
Light travels faster than sound and this looks to have been taken from a fair distance away from the actual car on track.

...which it definitely is...
All the F1 cars are, they all run antidive. The trick there is how much relatively. They might have canted both wishbones and actually ended up with less AD, not more. But a lot of people seem to just see a tilted wishbone and start exclaiming it's some sort of magic anti-dive philosophy like happened with RB the other year.

If you just took two parallel wishbones and rotated the rear links downwards to angle them. You'd end up with pro-dive, not anti-dive, because of the kinematic wheel recession.
It depends if also the wheel joint rotate with the wishbone as well... If is only the links of the wishbone to the chassis to ratate you cannot obtain pro-dive, as the wheel's caster and lead point stays the same

The inboard chassis points set that, not the outer joints, the inner two points set the wishbone arcs.

As someone already said, light travels faster than sound, and it's taken from some distance away from the track. And audio and video files aren't always well synced depending on what encoding they went through too.

Watch the video from 1.18 - 1.21 , play it on 0.25 slow speed and see if you notice something, active suspension ?
The car is fairly low and parallel before braking point into the turn, as soon it's entering the braking zone , before lift off the rear suspension gets dynamic (the rear of the car stiffness and more rake is observed before the brake is applied?

Active suspension is one of the most obviously illegal things in F1 and it would be visible the minute the car is on the track. Why would Ferrari even bother spending money on it?

Maybe they mean “some clever mechanical solution that creates the effect of active suspension”? Still, I don’t see it personally.

What struck me is how good the change of direction seemed. Sometimes I think there’s an impact of the handheld mobile camera conferring a sense of speed that doesn’t come across in the high quality broadcasts (which tbh isn’t great but totally separate conversation) - so we can take it with a pinch of salt - but the car did appear pretty nimble.

The thing I think I can say with most confidence is that it doesn’t look like a car with any fundamental issues, which is great news for a shakedown.

Way too early and too little footage to draw any meaningful conclusions about performance or behaviour. With low fuel and nowhere near qualy-like laps, everything will always look good and settled :)

More contain and downwash the turbulent flow than rectify it, but yes, something like that

It is filmed from quite a distance, so there is a delay in the sound. All you see there is the weight transfer when he hits the brakes.

basically, according to Franco Nugnes (I don't know if a reliable source), the front part of the chassis is lower than last year, and this creates a tunnel that guides air through the venturi tunnels and the bypass-duct (s-duct), in Ferrari was called like so.
