Ferrari is targeting a repeat of its impressive Mexico City Grand Prix performance at Interlagos, but the 2026 Brazilian GP will present a different technical challenge for the SF-26. Meanwhile, Mercedes faces an important decision over whether to introduce another power unit, potentially affecting George Russell and newly crowned world champion Andrea Kimi Antonelli.
Brazil brings Formula 1’s three-race American sequence to an end, with none of the events having featured a clear favourite beforehand. It reflects a championship in which the performance gaps between the leading four teams have rarely been smaller, making weekend preparation and execution increasingly decisive. Ferrari understands this better than most and hopes to reproduce the excellent work carried out in Mexico City, where its competitive advantage was ultimately undermined by the on-track battle between Charles Leclerc and Lewis Hamilton.
Why Ferrari’s Mexico GP advantage could be different in Brazil
In terms of outright performance, Ferrari emerged as the strongest team during the Mexican Grand Prix weekend. The upgrades introduced in Austin broadened the SF-26’s operating window, making the car more effective under acceleration out of slow corners. The Brazilian Grand Prix will provide another important assessment of the package’s effectiveness.
However, the conditions at Interlagos will differ considerably from those encountered in Mexico City, beginning with the altitude.
Although the Brazilian circuit is also situated at a relatively high elevation, it stands approximately 800 metres above sea level, comparable to the Red Bull Ring in Austria and well below Mexico City’s 2,200 metres.
The thinner air will still reduce engine performance, although its effects will not necessarily be identical to those experienced during the previous race weekend.
In Mexico, the predominance of slow corners particularly rewarded strong engine response at low revs. This is one of the strengths of Ferrari’s power unit, which benefits from a smaller turbocharger. The resulting responsiveness helped the Maranello team perform effectively in the traction zones, an advantage also highlighted by the analysis of Ferrari’s reduced turbo lag and Mexico GP performance.
Interlagos could tell a different story. Its more flowing layout may place greater emphasis on outright engine power, as was already the case in Austria.
The circuit’s corner characteristics represent another significant difference. Although Interlagos features predominantly medium- and low-speed corners, these tend to be longer and more rounded than the tight bends found in Mexico.
Stability through the middle of corners, traction while steering input is still applied and braking while cornering will therefore be particularly important. Conversely, there are fewer heavy braking zones where drivers can brake with the steering wheel straight. According to Brembo, Interlagos has a braking-system severity rating of just 2 out of 5, with drivers spending approximately 20% of their total lap time on the brakes.
These characteristics will offer a further test of whether Ferrari’s Austin developments have genuinely improved the SF-26 across a wider range of conditions, rather than simply making it particularly competitive at certain circuits. That question is also relevant to the team’s longer-term development direction, as explored in the analysis of Ferrari’s 2026 upgrades and their potential importance for 2027.
Mercedes faces important engine decision for Kimi Antonelli and George Russell
Ferrari will attempt to repeat what worked so well in Mexico City, where the team arrived with an excellent baseline setup that required very few adjustments throughout the weekend.
However, achieving another strong result will demand almost flawless preparation and tyre management. The same applies to Ferrari’s closest rivals, particularly Red Bull and Mercedes.
Max Verstappen and Red Bull have every reason to target a fourth victory in five races. Interlagos features relatively few high-speed corners, which should suit the RB22 given that this has been one of the car’s few remaining weaknesses.
For Mercedes, much of the Brazilian weekend could depend on whether the team decides to introduce another power unit. An updated engine developed under the Additional Development and Upgrade Opportunities (ADUO) framework could make its debut at Interlagos. The modifications primarily concern the turbocharger.
Should Mercedes introduce the updated specification, George Russell would automatically receive a grid penalty. Andrea Kimi Antonelli, on the other hand, can still fit a new turbocharger without incurring a penalty.
Nevertheless, the Italian driver indicated at Monza that he would need another engine before the end of the season. Brazil could be a suitable venue for such a change because Interlagos offers relatively good overtaking opportunities, potentially allowing drivers to recover positions after starting further down the grid.
The decision is particularly significant for Mercedes, which arrives in Brazil with Andrea Kimi Antonelli already confirmed as the 2026 Formula 1 world champion and the Constructors’ Championship still to secure mathematically.
McLaren brings major aerodynamic upgrades to Interlagos
McLaren also arrives in Brazil determined to move beyond its current position as the fourth-strongest team.
The Woking-based outfit has already announced that an updated floor will make its debut at Interlagos, alongside developments previously tested in Austin. New front and rear wings are also expected to appear during the Brazilian Grand Prix weekend. Their design philosophy will be similar to that planned for McLaren’s 2027 Formula 1 car.
The main objective is not simply to increase aerodynamic downforce. Instead, McLaren wants to broaden the operating window of the MCL40, making the car easier to drive consistently and allowing its drivers to reproduce competitive performance more reliably. These developments could prove particularly important at a circuit where stability through longer corners and consistent traction are essential.
Brazilian GP tyre degradation could make race pace more important than qualifying
Tyre management is expected to be one of the defining factors of the Brazilian Grand Prix weekend.
Pirelli has selected the C3, C4 and C5 compounds, a softer allocation than the one used for the 2025 edition of the race.
Combined with the circuit’s moderately abrasive asphalt, these compounds are expected to produce significant thermal degradation, particularly at the rear axle. This could make two-stop strategies a realistic option.
Greater tyre degradation and more varied strategies should also create additional overtaking opportunities, while energy management is not expected to be particularly critical at Interlagos. Unlike Mexico City, where maintaining track position was especially important, the Brazilian Grand Prix is expected to place greater emphasis on sustained race pace than starting position.
For Ferrari, this means that qualifying performance alone may not be enough to secure a strong result. Managing tyre temperatures and maintaining consistent pace over longer stints could prove decisive. Teams will therefore need to use their practice sessions carefully to understand tyre behaviour, especially through the sections between Turns 3 and 5 and at Turns 8 and 9, where the circuit has been resurfaced ahead of the event.
These areas could influence tyre performance and the balance of the cars, making Friday’s running particularly valuable for evaluating setups and longer runs. Fans can explore the observed lap times, tyre-stint pace and consistency of the leading drivers through the F1 Practice & Long-Run Analysis tool.
Ferrari heads to Brazil with no clear favourite among F1’s leading teams
Another important uncertainty is the weather. Interlagos is well known for its frequent rain showers, which can quickly transform circuit conditions and complicate the strategic picture.
With Ferrari hoping to carry its Mexico City form into another weekend, Red Bull targeting further victories, Mercedes considering power unit changes and McLaren introducing aerodynamic updates, the competitive order remains difficult to predict.
The combination of potentially high tyre degradation, strategic variation and changing weather conditions means that race execution could prove just as important as outright performance.
Ferrari’s priority will be to establish another strong baseline setup and make the most of the improvements introduced in Austin, while ensuring that its drivers can convert the SF-26’s performance into a competitive result.
There is no clear favourite heading into Interlagos. The only certainty is that Andrea Kimi Antonelli arrives in Brazil as the newly crowned Formula 1 world champion, determined to help Mercedes mathematically secure the Constructors’ Championship as well.
The weekend will also provide an opportunity to assess how Ferrari’s recent improvements translate to a circuit with different aerodynamic, power unit and tyre-management demands. The full 2026 Brazilian Grand Prix schedule includes the practice sessions, qualifying and race times for Interlagos.
