If you prefer a quick read, you will find the two-minute version at the bottom.

Scuderia Ferrari will arrive at the Autódromo Hermanos Rodríguez in Mexico City with plenty of doubts over its Power Unit, but also some confidence based on the positive results delivered by the upgrade package that made the SF-26 extremely solid at the recent United States Grand Prix.

The outright lap-time contribution of the changes introduced by the Maranello team was played down by everyone who discussed them before the Austin race, and that may well be true. However, it is worth remembering that Formula 1 cars are extremely complex systems, in which the balance and harmony between the various elements — the so-called “package” — often matter more than the absolute performance of an individual component.

The importance of “stability”, including in a car’s aerodynamics

More downforce or greater stability? Ferrari's technical choice on the SF-26

Serra’s team revised the airflow management of the entire lower section of the car: the floor inlet profiles were reworked, along with the diffuser volume and the shapes of its associated internal fences.

The sidepod has been reshaped with additional volume and, as stated in the documents published by the Federation, the objective is clear: “to simultaneously increase the quality, energy and stability of the flows directed towards the rear of the car”.

When a single-seater first takes to the track, particularly one born under entirely new regulations such as the SF-26, the usual approach is to explore a general concept without excessively pushing or conditioning the airflow.

Every surface affects the airflow around it and, using a simple wing as an example, attempting to impose too much conditioning can lead to instability, preventing the intended target from being achieved.

With developments introduced after the car’s first on-track version, in addition to addressing any issues encountered in real-world running, aerodynamicists always seek to increase the influence of the surfaces on the airflow in order to extract more from the car’s overall concept. Very often, that means trying to generate more overall downforce.

Clearly, as the limits are pushed, instabilities can emerge, just as a wing can be driven into stall by excessively increasing its angle of attack without introducing further countermeasures.

Is it more advantageous to remain within a known aerodynamic map?

More downforce or greater stability? Ferrari's technical choice on the SF-26

Ferrari has modified the SF-26 but, compared with McLaren and Mercedes, has remained faithful to the car’s original concept. It is as though it has chosen to move in a known direction, fully aware of where and how to push for a different conditioning of the airflow around the bodywork while keeping it stable and predictable.

It is no coincidence that the Prancing Horse’s updates correlated with expectations and were successful, unlike those of Mercedes and McLaren, with the latter no longer able to find its way back to competitiveness.

Mercedes pushed the airflow strongly downwards and towards the centre of the car with the latest version of the W17, but has struggled considerably to understand whether the step taken was genuinely forward and what the car’s new operating map might be.

McLaren has reshaped the entire sidepod, with the surfaces around the sidepod inlet now markedly different and more influential on the air flowing around them. It could be an extremely promising concept, but it undoubtedly places the MCL40 in unfamiliar aerodynamic territory that has yet to be understood.

Such a radical change is made during the season above all when it is considered likely to pay off not so much immediately, but in the future, once there has been time to study and mitigate its negative effects.

Ferrari, then, has achieved a system that is not necessarily capable of generating more downforce in absolute terms, but can generate it with greater stability.
Having done that, there is always scope to move further in a more extreme direction. Once, for example, the diffuser has adopted an efficient geometry and all the airflow feeding it is controlled and sufficiently energised to prevent it from stalling, its effect can be enhanced by pushing its geometry further in a continuous search for the limit.

However, negative effects cannot be ruled out. Leclerc himself spoke of an operating window that appears to have narrowed, especially in qualifying. Indeed, a temperature change of just a few degrees between Q2 and Q3 in Austin proved costly — perhaps costing Ferrari victory in the Grand Prix.

Setting aside all speculation, the encouraging signal delivered by the latest SF-26 upgrade must be acknowledged, as must the fact that every update introduced on the car has delivered during the season now approaching its conclusion. Ferrari will probably secure second place in the constructors’ standings, despite the substantial Power Unit deficit.

Mexico GP: track characteristics and tyre compounds selected https://www.formulawebmagazine.com/news/23664/mexico-gp-track-characteristics-and-tyre-compounds-selected Formula 1 is ready to take on the second round of its American triple-header this weekend at the circuit named after brothers Pedro and Ricardo Rodríguez in Mexico City, a unique venue on the calendar thanks to its altitude of more than 2,000 metres above sea level.

For the 2026 edition of the Grand Prix, Pirelli has selected the softest trio in its range: C3 as the Hard, C4 as the Medium and C5 as the Soft. This is a different choice from last year, when a compound step was attempted with the C2 used as the Hard, a solution that ultimately proved less interesting from a performance perspective than the softer alternatives.

The main new feature of the weekend is the resurfacing of a large section of the circuit. The work covered the stretch from Turn 16 to Turn 1 and the section from Turn 7 to Turn 16, leaving only the first sector largely unchanged. New asphalt is usually associated with higher grip levels and less roughness than older surfaces. However, it will be important to assess its actual characteristics during the early stages of the weekend.

The Autódromo Hermanos Rodríguez is traditionally one of the least demanding circuits for tyres. Its many low-speed corners and limited lateral loads tend to keep wear under control. At the same time, the thin air reduces the aerodynamic downforce generated by the cars, increasing tyre sliding and making graining a factor that must be monitored closely. With a new, smoother asphalt surface, this characteristic could play an even more significant role in determining strategy.

In Mexico, the track is often quite dirty during the opening sessions, with grip improving significantly lap after lap. This year, that evolution could be even more pronounced given the resurfacing work.

From a strategic standpoint, the circuit's low severity and the behaviour of the three compounds at tracks with similar characteristics could favour a one-stop race. Tyre management to extend stints will nevertheless remain an important factor, particularly as the rear axle is subjected to the greatest stress.

Mexico GP: track characteristics and tyre compounds selected

The difference between the various strategic options could depend more on the confidence each driver can draw from a particular compound than on the tyres' actual wear limit. As seen at several events this season, some teams may be more inclined towards the softer compounds to benefit from the extra grip available, while others may favour the consistency and stability offered by the Hard compound.

In any case, the Soft compound could once again play a central role. The C5 has shown excellent characteristics at low-intensity circuits and could prove an interesting option not only in qualifying but also in the race, expanding the range of strategic possibilities compared with previous seasons.

Another aspect to watch will be braking performance. The altitude reduces aerodynamic efficiency and can make the management of the most demanding braking zones more challenging. The long main straight leading into Turn 1 could increase the risk of lock-ups, especially in the early stages of the weekend when grip levels are still limited.

Last year

Last year's starting grid was split between one-stop and two-stop strategies. Most drivers chose to start on soft tyres, while only six cars opted for mediums and two for hards. The softest compound was also used by those on a two-stop strategy, fitted for the final stint thanks to extremely low degradation and the absence of graining.

A special podium cap

Pirelli's podium cap for the Mexico City Grand Prix celebrates Día de los Muertos, which falls on race Sunday. The special-edition cap, to be worn by the drivers on the podium, features a black base decorated with traditional Mexican artistic motifs. The Podium cap was designed by Denis Dekovic and produced by Pirelli Design. As with the other special editions, this one is already available to buy on the dedicated website.

Thin air and a small turbo: why Ferrari faces a greater risk in Mexico https://www.formulawebmagazine.com/news/23663/thin-air-and-a-small-turbo-why-ferrari-faces-a-greater-risk-in-mexico The excellent performance delivered by Ferrari at the Circuit of the Americas was perhaps one of its most convincing of the entire season.

Although it did not result in victory, the race contested by both SF-26s was solid, with the car bolstered by an upgrade package that worked as the technicians had expected, without the negative surprises that have characterised the developments introduced by McLaren and Mercedes.

Optimism and satisfaction, however, give way to justified concern ahead of the next race, to be held in Mexico City at more than 2,200 metres above sea level.

Mexico is an exceptionally demanding test for power units

Aria rarefatta e turbo piccolo: perché la Ferrari rischia di più in Messico

The thin air at the Autodromo Hermanos Rodriguez has always been an extreme test for power units and their cooling systems, causing a significant reduction in available power. However, it could be the most punishing venue of all for the unit powering the SF-26.

Furthermore, the compact turbocharger assembly that characterises Maranello's power unit could be particularly disadvantaged compared with manufacturers that have opted for a relatively larger turbine wheel.

Moving from sea level to high altitude changes the operating point on the compressor map.

To continue supplying the same mass flow to the combustion chambers, the turbine wheel must necessarily rotate faster.

Every design parameter changes and the turbo struggles

Because of the lower ambient pressure, all the calculation parameters change and the corrected air flow that the compressor must supply increases significantly, as do rotational speed and the compression ratio.

As well as reducing the turbo's efficiency, this means hotter gas reaches the intercooler on average, placing even greater strain on this heat exchanger, especially where it is air-to-air, although other types, air-to-liquid or hybrid systems, are also present on the grid.

There is a risk that the compressor enters a choked-flow region, meaning the maximum possible flow is limited by the speed of sound at the narrowest passage section: on the compressor map, the operating point moves to the right of the ideal area and efficiency collapses.

Although in reality everyone operates below the optimum flow target, reducing it slightly and pairing it with a generally richer fuel mixture, a compressor with a larger turbine wheel has a blade tip speed which, at the same rotational speed, can more easily compensate for all these effects.

For this reason, Ferrari's Power Unit, already lacking overall, could suffer even more in Mexico because of its smaller turbo.

Ferrari's excellent performance in Texas must be treated with the appropriate caution: it is not a flash in the pan, but it is unlikely to be repeated this weekend in Mexico, which is the least representative test for assessing the impact of the latest upgrades.
