Ferrari’s disappointing Brazilian Grand Prix was not simply the result of Lewis Hamilton ignoring a crucial pit-stop instruction. Although the seven-time world champion’s decision cost him an opportunity to challenge Liam Lawson, the SF-26’s biggest problems at Interlagos concerned tyre temperatures, inconsistent race pace and strategic choices that left both Ferrari drivers unable to recover. Charles Leclerc finished eighth, ahead of Lewis Hamilton in ninth, completing another frustrating race for the Maranello team.
The changing conditions made tyre management decisive, with drivers switching from Intermediates to Soft slicks as the track dried before returning to Intermediates when rain arrived towards the end. Most teams followed similar strategies, but differences in tyre warm-up, stop timing and driver decisions had a major influence on the final classification. Ferrari was among those that failed to make the most of the opportunities available.
Ferrari’s Brazilian GP strategy problems began long before the final pit stops
The 2026 Brazilian Grand Prix was relatively straightforward in terms of the tyre compounds available. Only the Intermediate and the C5 Soft were used, with engineers and drivers monitoring the changing track surface to determine when to switch between them.
The most common approach involved three stops, following an Intermediate-Soft-Soft-Intermediate sequence. However, some drivers avoided the additional stop for another set of Softs, instead completing the race on an Intermediate-Soft-Intermediate strategy.
George Russell, Charles Leclerc and Sergio Perez were the three drivers who managed to avoid that extra stop. The remaining competitors generally returned to the pits during the middle phase of the race to fit fresher tyres.
With rain returning in the closing stages, the Intermediate-Soft-Intermediate strategy ultimately proved the most effective option. The difference in stop timing and stint length was particularly significant, as drivers who could preserve their Soft tyres were able to avoid spending additional time in the pit lane.
The various approaches can be explored through the Formula 1 tyre and stint analysis, which allows comparisons of tyre compounds, stint lengths and race performance.
Lewis Hamilton’s ignored Ferrari pit-stop call proves costly
Lewis Hamilton’s refusal to follow Ferrari’s instruction to change from Soft tyres to Intermediates became one of the most discussed strategic moments of the race. As the rain intensified and the track became increasingly wet, the British driver remained on slick tyres despite the pit wall’s request to bring him in.
That decision effectively eliminated his remaining opportunity to fight Liam Lawson for position. Had Lewis Hamilton followed the team’s instruction, he could have been in contention to challenge the Racing Bulls driver, although seventh place appeared to be the best realistic outcome.
Instead, the Ferrari driver struggled to reach the pits on tyres that were no longer suitable for the conditions, eventually finishing ninth.
The episode reinforced concerns about the level of trust between Lewis Hamilton and the Ferrari pit wall. His decision to continue rather than immediately follow the instruction proved costly, particularly when the team was already struggling to manage the changing track conditions.
Nevertheless, the strategy disagreement was not the primary reason Ferrari lacked competitiveness at Interlagos. Even with a better final pit-stop decision, the Italian team’s overall performance suggested that a substantially stronger result was unlikely.
Lewis Hamilton’s remarkable start gives way to Ferrari tyre problems
The race had initially promised considerably more for Lewis Hamilton. Starting from 19th, the seven-time world champion produced an exceptional opening lap, climbing to ninth within the first few corners.
His early progress was comparable to the impressive getaway achieved by Max Verstappen, who also gained considerable ground during the opening stages.
However, Ferrari’s encouraging start quickly unravelled. After only one or two laps, Lewis Hamilton began losing competitiveness as his pace on Intermediate tyres deteriorated sharply.
While Max Verstappen managed to bring the Intermediates into their effective operating range and continued his recovery towards the top three, the Ferrari driver struggled to maintain the performance required to defend his newly gained positions. By approximately lap 20, the Red Bull driver was already approaching the leading group, whereas Lewis Hamilton had lost the momentum generated by his excellent start.
Conditions improved for the Briton once he switched to Soft tyres, but recovering the lost ground remained difficult. Ferrari subsequently opted for another pit stop to fit a second set of C5 Softs, adding to the strategic complications of an already challenging race.
These difficulties reflected the broader tyre-temperature concerns surrounding the Ferrari SF-26 at Interlagos, which had already emerged during the weekend.
Charles Leclerc’s Soft tyre struggles undermine his Brazilian GP recovery
Charles Leclerc experienced a different but equally frustrating race. After an unremarkable start, the Monegasque managed his Intermediate tyres effectively and worked his way into the top ten.
His recovery then suffered a major setback when he switched to the C5 Soft compound.
Like Lewis Hamilton, Charles Leclerc struggled to generate sufficient tyre temperature, but the problem persisted for longer. While the Briton’s difficulties on the Softs lasted only a few laps, his team-mate required considerably more time to bring the tyres into the correct operating window.
The consequences were substantial. Having recovered into the top ten, Charles Leclerc dropped back to approximately 13th or 14th position, effectively returning to the area of the field from which he had started. Once the tyres finally reached the appropriate temperature, the Ferrari driver was able to manage the compound more effectively. Unfortunately, the time lost during the initial phase of the stint had already compromised his recovery.
Charles Leclerc nevertheless benefited from avoiding an additional pit stop, extending his Soft tyre stint before making the final switch to Intermediates.
That strategy allowed him to finish ahead of Lewis Hamilton and gave him an opportunity to challenge Liam Lawson during the closing stages. However, contact between the two drivers disrupted the result, and a five-second FIA penalty left the Ferrari driver eighth at the finish.
How Lando Norris and Max Verstappen made better use of the changing conditions
Ferrari’s problems became more apparent when compared with the performances of its rivals.
Lando Norris secured victory for McLaren largely through an excellent stint on the C5 Soft tyres immediately after switching from Intermediates.
Although Andrea Kimi Antonelli initially gained the advantage at the start, Lando Norris managed to bring his slick tyres up to temperature considerably faster than the Mercedes driver.
That advantage enabled him to take the lead and retain it for the remainder of the Grand Prix. Max Verstappen also delivered an outstanding performance, extracting strong pace from each phase of the race. His effective management of the Intermediate tyres was particularly important during the early stages, allowing him to continue gaining positions while several rivals struggled with grip and tyre temperatures.
Isack Hadjar, Liam Lawson and Oscar Piastri also completed solid races, while George Russell finished ahead of Andrea Kimi Antonelli despite spinning in the pit lane after his first stop.
For Ferrari, these results demonstrated how much performance could be gained or lost through tyre preparation and management, even when the overall pit-stop strategies were similar.
Mercedes also struggles with Soft tyre warm-up at Interlagos
Ferrari was not the only leading team to encounter difficulties with the C5 Soft compound.
Andrea Kimi Antonelli experienced a particularly challenging opening phase after replacing his Intermediate tyres with Softs. The Mercedes driver struggled to bring the slicks into their effective operating range, making two mistakes at Turn 1 that cost him the race lead and contact with the front of the field.
George Russell also encountered difficulties, losing control of his car at the pit-lane exit following his first stop.
The incidents highlighted how sensitive the tyres were to the conditions at Interlagos. Even Mercedes, which had repeatedly demonstrated excellent tyre management throughout the season, experienced an unusually difficult race in that respect.
Until Brazil, the German manufacturer had regularly established a substantial advantage over its rivals through its understanding of tyre behaviour. Interlagos represented one of its first significant setbacks in that area.
At the same time, McLaren and Red Bull demonstrated encouraging potential for further development over the winter. Despite Andrea Kimi Antonelli and Mercedes having already secured the Drivers’ and Constructors’ World Championships respectively, the battle for 2027 was beginning to take shape.
Defending both titles may prove more difficult than winning them in 2026, particularly if rival teams can build on the competitiveness demonstrated during the Brazilian Grand Prix.
Pirelli explains why Interlagos tyre conditions complicated race strategy
Following the race, Pirelli motorsport director Dario Marrafuschi explained that the weather had played a decisive role in determining the available strategies.
According to Dario Marrafuschi, rain before the start created substantial differences in grip around the circuit, making Intermediate tyres the necessary choice for the opening stint. As the track gradually dried, the Intermediates continued to provide consistent performance while approaching the crossover point at which slick tyres became the quicker option.
The main degradation observed during this transitional phase was thermal, with Pirelli also recording graining caused by the drying surface, particularly on the right-hand side of the tyres.
Once conditions allowed drivers to switch to slicks, the C5 Soft proved to be the most suitable compound. Dario Marrafuschi explained that the relatively low air and track temperatures helped limit degradation, encouraging some teams to consider completing the race without making another stop.
However, the return of rain in the closing stages forced teams to reconsider their strategies, making another switch to Intermediates necessary.
Overall, the Pirelli representative considered that both the Intermediate and Soft compounds had performed in line with expectations, despite the challenging conditions.
Ferrari’s biggest Brazilian GP weakness was tyre management, not strategy alone
The final classification reflected a broader performance problem for Ferrari rather than a race decided exclusively by Lewis Hamilton’s late pit-stop decision.
Both drivers experienced serious difficulties bringing their tyres into the correct operating window, with the C5 Soft proving especially troublesome. Charles Leclerc lost valuable positions while waiting for the compound to reach temperature, while Lewis Hamilton was unable to sustain his excellent opening progress on Intermediates.
The pit wall’s decisions added to the disappointment, particularly the additional Soft tyre stop for Lewis Hamilton and the late disagreement over the switch back to Intermediates. Yet even with improved execution, Ferrari’s realistic opportunities appeared limited to challenging Liam Lawson rather than competing with the leading teams.
The deeper concern is that the SF-26 could not consistently extract the performance available from its tyres, leaving both drivers vulnerable whenever conditions changed. At Interlagos, the difference between finishing eighth and ninth and fighting further up the order was not simply about choosing the correct moment to pit. It was also about generating grip quickly enough to make each stint competitive.
For Ferrari, solving that problem is just as important as improving communication between the drivers and the pit wall.
