Ferrari SF-26

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.

Crash structure winglet / diffuser extension has been upsized?

Blown rear wing. Exhaust will just shoot straight up.

Yea it's a blown diffuser, no?

Motorsport turkey says this may be worth 0.15-0.25s alone and they deliberately saved this update for late. Stella spent a long time examining this region

Can this be copied by others before Race 1?

Looks like it's a whole thing with the floor, they would need to be making it now, no way you can make and ship a floor with 15 days to go.

No.

"Engineers are permitted to position an aerodynamic device in that area of the car, provided it does not exceed a distance of 60 millimeters from the half-shaft (or driveshaft). Typically, this constraint prevents the device from extending beyond the tip of the exhaust; however, the Maranello engineers managed to bypass this hurdle by shifting the differential to the furthest possible rearward position, utilizing the space beneath the rear crash structure. The entire area was designed from the outset with the introduction of this innovation in mind, which is codenamed FTM within the Scuderia’s garage."

With car taking corners at much higher RPM for harvesting purpose + harder spool up of the turbo/anti-lag, exhaust gases should be exiting faster at low-speed corner now. Question is what kind of flow are they targeting, are they working the lower rear wing support harder, somewhat extending the general height of the diffuser?
One thing for certain they've been quite adventurous with the diffuser geometry right out of the gate, blown or not.

Other tiny thing I've been wondering about this car, there's a kind of small box rearward of the viking horns, in the white section. It's been there since launch and I wonder what's up there high on the chimney that needs extra bodywork.

These are the things I would expect from Ferrari. They're always incredibly innovative, especially on new regulation cycles. Not sure about this being hard to copy yet, but it's certainly very smart considering that it plays right into the regulation's nature of running higher revs through corners.

they should redesign all the rear because the position of the aero device is linked to that of the rear axle i.e. the differential

It will be very difficult to copy. Notice how narrow Ferrari's exhaust pipe is compared to the Mercedes and RBPT. Smaller pipe carries higher gas velocity so even the engine concept was designed to push the highest velocity jet of air at the winglet. The engine was tuned for this narrow pipe. There's a lot of details here that will be very difficult for anyone else to get working nearly as effectively. Engines and exhaust will be homolagated in 12 days.

That's before we get to the position of the rear differential with respect to the winglet, which Ferrari also moved to enable this solution. No one is going to be able to copy this.

I see. They will likely carry some advantage in this area for the whole season then. It's similar to how the SF70H high sidepods were pretty much impossible to copy in-season as they required the whole chassis to be designed a certain way. I can see this being way "easier" laptime though, as Ferrari are "free" to chase gains elsewhere as well.

I would consider this the first real loophole of these regulations.

It seems that the plate near the exhaust is also present in the lower section of the car. An interesting detail that could have implications for heat management and rear-end aerodynamics.
