Ferrari’s Brazilian Grand Prix turned into one of its most difficult Sundays of the 2026 Formula 1 season, with three distinct performance problems combining to undermine the SF-26 at Interlagos. Lewis Hamilton’s aggressive tyre-pressure strategy, the car’s inability to maintain the correct tyre temperatures in cold conditions and a significant straight-line speed deficit all contributed to a race in which both Ferrari drivers struggled to compete.
After a qualifying session that had offered some encouraging signs, particularly when taking penalties into account, Ferrari suffered a dramatic loss of competitiveness on Sunday. Lewis Hamilton initially gained eleven positions on the opening lap, but his pace soon deteriorated, while Charles Leclerc encountered difficulties in both wet and dry conditions. Beyond the three technical problems, the race also exposed a delicate relationship between the drivers and the Ferrari pit wall, raising further questions about how the team manages strategic decisions under pressure.
Ferrari’s aggressive tyre-pressure gamble helps Lewis Hamilton gain eleven positions
The first problem concerned the approach Ferrari appeared to adopt for Lewis Hamilton’s start. The Italian team seems to have chosen particularly high pressures for the intermediate tyres, with the aim of generating temperature and grip as quickly as possible.
It was an aggressive decision that initially appeared to work brilliantly. Lewis Hamilton produced an exceptional opening lap, recovering eleven positions and demonstrating how effective the tyre preparation could be over a short distance.
However, the downside emerged almost immediately. Excessively high tyre pressures reduce the effective contact patch between the rubber and the asphalt, encouraging sliding and surface overheating. On intermediate tyres, this can also accelerate the deterioration of the tread blocks.
Lewis Hamilton consequently wore out his set of intermediates very quickly, losing much of the advantage gained during his extraordinary start within just a few laps. The situation illustrated the risks associated with Ferrari’s aggressive tyre-pressure gamble at Interlagos, which provided immediate performance but proved much less effective over a longer stint.
The decision was probably also influenced by expectations that the circuit would dry rapidly. Sacrificing the durability of the intermediates would have made sense if they were only required for a handful of laps before the switch to slick tyres.
Instead, the track dried more slowly than expected, and wet-weather tyres remained necessary for approximately fifteen laps. That made the gamble considerably less rewarding than Ferrari might have anticipated.
Ferrari team principal Fred Vasseur also referred to tyre pressures when explaining Lewis Hamilton’s sudden performance decline following his outstanding start, reinforcing the interpretation that the initial tyre configuration had played an important role.
Ferrari SF-26 struggles to generate tyre temperature in cold Brazilian GP conditions
The second problem was more widespread and affected both Ferrari drivers. Beyond the particular circumstances of Lewis Hamilton’s opening stint, the SF-26 struggled enormously to bring its tyres into the correct operating window and keep them there.
With exceptionally low track temperatures, Ferrari found it difficult to generate and maintain the heat required for consistent grip. The tyres frequently remained on the cold side of their ideal operating range. When the drivers attempted to recover performance by pushing harder, the resulting sliding could instead overheat the tyre surface.
This weakness was not entirely unexpected. Throughout the season, the SF-26 had repeatedly struggled to bring soft tyres up to temperature, despite showing an ability to control overheating effectively in much warmer conditions.
The contrast was particularly striking. Ferrari had demonstrated enough performance to win races with track temperatures reaching 50°C, but at Interlagos, with the asphalt measuring approximately 23°C in the rain, the car struggled to generate sufficient tyre temperature to reach the ideal operating window.
The result was an extremely difficult car to drive, with only brief periods during which the tyres appeared to function correctly. The changing conditions made maintaining consistent performance particularly challenging. Charles Leclerc, who started with less aggressive tyre pressures than his teammate, suffered from these difficulties particularly on the intermediates, both during his opening stint and towards the end of the race.
Lewis Hamilton encountered similar problems in the closing stages, by which time his overall race result had already been severely compromised.
The scale of Ferrari’s tyre-temperature problems during the Brazilian Grand Prix illustrated how severely the SF-26’s performance could deteriorate when conditions fell outside its preferred operating range.
The different tyre choices and their impact across the race can also be explored through the Formula 1 tyre and stint analysis, which allows readers to examine compounds and stint sequences in greater detail.
Ferrari loses up to eight tenths on the straights despite Charles Leclerc’s competitive pace
The third major weakness became particularly apparent during the dry phases of the Brazilian Grand Prix and concerned Ferrari’s straight-line speed.
Interlagos sits at an altitude comparable to that of Spielberg, and the conditions once again brought to light difficulties previously observed with Ferrari’s power unit. These limitations were compounded by a rear end that frequently struggled to transmit power effectively to the asphalt.
Charles Leclerc’s performance during the long middle stint on soft tyres provided a particularly revealing example. The Monegasque managed to find reasonably competitive race pace, running broadly in line with his rivals. However, he reported losing as much as eight tenths of a second on the straights compared with the Alpine he was battling.
That was an enormous deficit, making it almost impossible for Charles Leclerc to convert his available pace into overtaking opportunities and recover positions. Even when the SF-26 performed relatively well through the corners, its difficulties on the straights prevented the Ferrari driver from fully exploiting that improvement.
The issue highlighted a crucial distinction between having competitive lap times and possessing the performance characteristics needed to overtake another Formula 1 car. Charles Leclerc could remain competitive over parts of the lap without necessarily having enough straight-line speed to complete a move.
Ferrari’s difficulties were consistent with the broader SF-26 performance problems identified in Brazil, where the team’s weaknesses were not limited to tyre management alone.
Lewis Hamilton and Charles Leclerc face another Ferrari pit-wall dilemma
Beyond the three technical problems, another aspect of Ferrari’s Brazilian Grand Prix deserves attention: the increasingly delicate balance between the drivers’ judgement and the strategic decisions made by the pit wall.
During the closing stages of the race, as the rain intensified, Lewis Hamilton decided to continue despite receiving an instruction to enter the pits. The decision left him driving on slick tyres as the circuit became too wet for them, resulting in a mistake that cost him additional time.
The British driver subsequently explained that he had not received sufficient information about the increasing intensity of the rain, although he accepted responsibility for his decision. The incident was less significant, both in its consequences and its seriousness, than what had happened in Singapore, but it nevertheless highlighted a problem that Ferrari should not overlook.
Charles Leclerc, meanwhile, had made a different strategic decision. Rather than completing a second pit stop for another set of soft tyres, the Monegasque wisely chose to remain on track and wait for the approaching rain.
Importantly, Charles Leclerc had more time to discuss the situation with the pit wall and reach a shared decision. Lewis Hamilton, by contrast, found himself having to make an immediate judgement as he approached the pit entry.
That difference is significant because it illustrates how the time available for communication can influence the relationship between a driver and the strategists.
Why Ferrari must rebuild trust between its drivers and strategists
The underlying issue appears to extend beyond these individual incidents. Ferrari may now be experiencing some of the consequences of previous strategic mistakes, with both drivers finding it increasingly difficult to place complete trust in the instructions they receive.
A driver’s willingness to take the initiative is understandable. In Charles Leclerc’s case, greater independence has frequently been encouraged when decisions from the Ferrari pit wall have appeared unconvincing.
However, modern Formula 1 is a sport in which engineers have access to enormous amounts of information, simulations and data that a driver cannot possibly process while racing.
When conditions change rapidly, decisions based exclusively on what a driver feels inside the cockpit can therefore become counterproductive, even when those instincts are understandable. The comparison with Red Bull is particularly interesting. Max Verstappen is arguably one of the most independent drivers on the grid and is rarely inclined to follow pit-wall instructions unquestioningly.
Nevertheless, Red Bull has demonstrated such strength in strategic decision-making over the years that it has frequently managed to convince even Max Verstappen to trust the team’s assessments.
Finding the correct balance between the instincts of the driver on track and the broader perspective of the engineers analysing the available data is essential. The objective should not be to prevent drivers from taking the initiative, but to establish a relationship in which their judgement and the expertise of the pit wall complement one another rather than come into conflict.
For Ferrari, the Brazilian Grand Prix exposed three distinct performance weaknesses: an aggressive tyre-pressure choice that quickly became costly, a car unable to consistently operate its tyres in the correct temperature window and a straight-line deficit that limited overtaking opportunities even when race pace improved.
Yet the weekend also demonstrated that solving the SF-26’s technical limitations will not be enough on its own. Ferrari must continue refining the delicate balance between driver independence and strategic authority if it wants to avoid making already difficult races even more complicated.
