How Ferrari's Imola spec offers clues to hit-and-miss upgrades

Ferrari arrived at Imola in relatively high spirits given its recent results, with the team having found the right combination of upgrades and retrogrades in recent races to help unlock some of the SF1000's hidden potential.

Although it still has a long way to go in its quest to return to the sharp end of the grid, its work over the last few races has not only resulted in a solid showing on track, it should also pay dividends going forward.

For Imola, the team once again took the opportunity to tune its downforce level at the front of the car, trimming the upper flap to shorten its chord around the site of the front wing adjuster.

This is remedial work that the team seems to be carrying out at the track, rather than sending new flaps to each venue. It is something we've not really seen from the Scuderia over the last few years.

This further signals the team's intent, as it adapts to the challenges that this season has thrown up and as it attempts to balance both its short and long term development goals.

Ferrari also opted to run with less downforce at the rear of the car too, returning to its gentle spoon-shaped rear wing.

You'll note that in this configuration the team has really pushed the design of the endplate further, with the wall thickness reduced around the mainplane and upper flap to expand the outer channel's influence on the airflow.

It's also interesting to see the hanging section of its endplate from this side too, as it shows that, whilst the elements are all connected, the forwardmost one acts like the tail seen on some rival cars. This creates a U-shaped guide rail for the airflow to follow as it enters from the other side.

The floor introduced at the Portuguese Grand Prix at Portimao was also retained by the Scuderia, as the team clearly felt the retrograded design, which featured three vertical fins ahead of the rear tyre, offered more performance than its predecessor.

Meanwhile, the diffuser, which is a throwback to the design used by the team at the first race of the season, was also kept for this weekend.

When compared side by side, we can see that the revised layout features just the two main vertical strakes either side of the central ramp, with the innermost two being solid rather than having slots in them.

The stiffening strap (red arrow) now connects all four of the diffuser elements together, rather than just the outer three from the diffuser introduced at the Styrian GP. This is likely in response to reducing flutter at a certain speed and perhaps brings with it a little more aerodynamic consistency.

The team also revised the diffuser upstand beneath the crash structure, trimming the section by hand by the looks of it. This is similar to the way it adjusts the front wing upper flap.

Meanwhile another flap, which appears to have been rapid prototyped, was added above it and strapped to the side of the crash structure (blue arrow).

Whilst Leclerc enjoyed another high points paying finish for the Scuderia, Vettel once again fell short. However, were it not for lap one damage and a long pit stop then the four-time champion may well have finished in the points.

Vettel's scuffle with Kevin Magnussen during the opening lap resulted in a broken the front wing endplate that he carried through the entirety of the race. This would clearly have an impact on aerodynamic performance but also meant that the team and driver had less data to work with too.

The section of Vettel's endplate that became lodged in Valtteri Bottas' bargeboard cluster, and cost the Finn a chance of the race win, has the thermal imaging camera attached to it, meaning Ferrari was flying a little blind on that tyre.

Remarkably the German's lap times hardly fluctuated though and his pace, considering the level of damage, was pretty decent, meaning he ran as high as fourth place at one stage in the race when the soft runners ahead of him pitted.

Vettel also had the misfortune of having a visor tear-off lodged in his rear wing at one point too.

But the moment that really changed the face of his race was the slow pit stop which cost him around 13 seconds due to a stripped thread on a wheel nut. This was especially damaging when we consider that Imola has a high pit stop delta, meaning you already lose a considerable amount of time relative to those on circuit.

All signs point to Ferrari being on the road to recovery and, with the arrival of a revised power unit scheduled for the start of next season, it may be able to close the gap to their rivals ahead a little further still.

It has owned up to the mistakes it made which led to its troubled W13. And while its task to return to title-challenging contention is not small, its 2022 season seems more like a blip than the beginning of a downward spiral.
