Gary Anderson on Ferrari’s major Red Bull-inspired F1 upgrade


My first reaction when seeing initial images of Ferrari's Imola upgrade package leaking from the team's recent Fiorano Formula 1 test was that the update was rather limited.

But now, after seeing more images from the Imola circuit, it looks like it's an overall package that – if Ferrari can get it all to work – should make a reasonable step up in performance.

Front wing

It's interesting to see at the outer end of the front wing flap assembly (purple arrow above), where it all reduces camber and overall cord length, where the Ferrari has such a major level of long cord (which I highlighted elsewhere) next to the green arrow ).

I'm pretty sure this works in conjunction with the detail I highlighted with the green ellipse (above). This is a continuation of the outer fender but opens up the frame's end panel gap, resulting in increased outer wash – although it is questionable what level of outer wash is acceptable.

Radiator inlet

The most significant change is the radiator inlet. In this comparison from old to new we can see that Ferrari has definitely been inspired by what Red Bull presented at the beginning of 2024.

Ferrari has always had a vertical inlet (highlighted by the vertical green line) and it is suspected that this was connected to the outlet duct on the side of the cockpit, forming what is commonly called an 'S-channel' for the bleed-off boundary layer that builds up on the side of the hull. Now this appears to have been integrated into the actual cooling inlet duct.

By doing this, Ferrari has been able to more or less maintain the size of the inlet (highlighted with yellow arrows) as before – but raise the lower surface to improve mass flow (highlighted with blue arrows) through the lower cutout in the front corner of the side.

The flow coming from the trailing edge of the front wing will now have less of an impact on cooling, so may allow Ferrari to get closer to the cooling limit required by the power unit package.

“S-DUCT” output.

This was the outlet for what was called the “S Channel”. This helped reduce the build-up of the boundary layer on the side of the hull but the exit flow (highlighted with blue arrows) from that channel would be so overcome that there would not be much energy left in it.

Ferrari also had this turn vane to help eliminate airflow from the 'S' duct, but with the distinctive green arrows, this flow likely had a reasonably negative impact on the overall upper body surface flow structure.

Now Ferrari is able to focus on improving this flow structure along the sides of the cockpit with a new spindle vane (purple oval).

Upper cooling outlet

Downstream, Ferrari changed the position of the upper cooling outlet, moving it further back.

It is also “larger”; Quantifying this style of exit can be difficult, and you need to make sure you simulate the radiator flow exactly, otherwise when the radiator starts to clog, it can cause backflow (which I highlighted with the green arrows above).

If this happens it can lead to all kinds of weird airflow problems. A range of vents, which can be modified to suit cooling requirements, can be a better way to manage this exit flow.

Subtle but vital adjustment of flooring

Ferrari has also opened up this small inlet channel (marked with yellow arrows) at the back of the floor. This will relate to the airflow being forced inside the tire as it rotates on the track surface (green arrows).

This flow is drawn around the tire contact patch into the vacuum as the rear tire emerges off the ground behind the tire contact patch – essentially acting like a vacuum cleaner, helping to seal the subfloor. It can also provide reasonable drag reduction.

Dramatic 'ski slope'

We talk a lot about the “ski slope” side aspect. This one I've highlighted with the blue arrow is rather dramatic and flows into the central part of the diffuser but also improves the effectiveness of the so-called “Coke bottle” area where the bodywork narrows, pulling more flow away from the front face of the tire.

It's interesting how simple and brutal the pull rod adjuster is (highlighted in green). In these days of ground effect, which carries a significant risk of porpoising, it's all about being able to improve rear ride height quickly and easily – if you have something too complicated, you'll never get the best out of your combination.

Rear wing details

The detail on the outer edge of the main plane of the rear wing and upper flap (highlighted by the yellow ellipse) is impressive.

It's all about minimizing the vortices created by pressure differences across the wing and endplate surfaces in this area.

We are used to seeing huge roosters' tails in wet conditions. They are still there but much reduced.

Great package

I'm sure there are more developments in the area that really matters – the floor – but from what we've had the pleasure of seeing I'm impressed.

This does not mean that everything will work immediately this weekend, but Ferrari did a filming day to verify the connection. Ultimately, Imola is just a stone's throw away from Maranello – so the team will do its best through the simulation to get the best results.
