Ferrari SF-26

[bananapeel23]

If it takes more than 400ms from start to finish positions I assume they will get a DQ, so if they run it, it must be within that time. But even if it is less than 400ms, or 0.4s, it might be a bit slow, causing rear instability right before braking, that is another question.

It will probably be deactivated manually while lifting and coasting or superclipping, meaning it shouldn’t impact braking stability.

But hopefully the next iteration gets it down to ~200ms or something, which would be crazy.

If the CFD's shown earlier in this thread are accurate and the wing creates a turbulence "bomb" every time it activates, maybe they wouldn't want to speed it up. I doubt that it would actually upset a following car that much, but it would be hilarious if it did. Brings to mind James Bond releasing an oil slick behind him, or a Mario Kart banana peel.

Cutting the deployment time in half seems like it would generate a disproportionate amount of stress on the wing. The wing would have to move twice as fast (in a reference frame that is moving with the car). That means the drag force in the "speed brake" phase would quadruple momentarily.

So it's probably not actually efficient to make the wing move faster. Motor would have to be more powerful (weight, energy), and wing would have to be stiffer (heavier).

Autoracer said that in China the SF-26 has a small modification to the rear suspension, has anyone managed to spot it?

I reckon it would be more efficient to have it close quicker, but opening isn’t likely to be very important at all.

Obviously I have no clue if the weight penalty of a quicker system is worth it, nor if the wing could even handle the pressure.

I think it matters how aggressive the affects of the flows are.

two vortices from the center & zooming past both ears of the driver ; in rain, either they dump more water on the visor or help the visor not get too wet.

Rear brake disc. The are not as many holes in the disc this year.

It is the opposite at the front. More holes in the 2026 brake disc and brake caliper lowered.

I would have thought halving the activation and deactivation times would increase stress on the mechanisms but decrease overall stress, as the wing would spend less time in transitioning through it's high drag, barn door position.

That video is clearly slowed down when the wing is moving. From the videos in full speed I think the wing is opening/closing in around 250ms-300ms (14-15 frames at 50fps). I'm sure they can do it faster tho

Here's the full speed clip (skip to 1:27):

It has already been discussed in this very thread that the actual deployment time of the wing is less than 300ms, from normal speed videos from bahrain. The onboard camera everybody keeps referencing was played in slow motion (the sound is a dead giveaway).

I strongly advise against using this contraption. Actuating the rotation seemed too slow and I think this thing is not ready yet. I consider this endeavor a high-risk and doomed for failure. Typical Ferrari: overreacting under pressure. They will only verschlimmbessern (trying to knee-jerk improve while doing the opposite) their near perfect car.

They will make it rotate faster for the race tk comply with the rules. They were obviously rotating slowly in testing for data gathering.

They seem quite large for just vortices? Looks like it influences air going to the airbox and horns.
