Ferrari reportedly altered the SF-26 setup after detecting a potential reliability problem on Charles Leclerc’s car during first practice at the 2026 Hungarian Grand Prix. The protective changes, introduced between Friday and Saturday, may help explain why the Maranello team lost performance just as the fight for pole position intensified.
The theory emerged from a technical discussion on AutoRacer and offers a possible new explanation for Ferrari’s sharp change of fortunes at the Hungaroring. Although the SF-26 appeared extremely competitive during Friday practice, its handling and overall effectiveness gradually deteriorated from Saturday onwards.
Ferrari SF-26 setup change followed Charles Leclerc reliability concern
Ferrari’s opening day in Hungary had been close to flawless. Cooler temperatures and favourable wind conditions appeared to suit the SF-26 while creating greater difficulties for some of its rivals, allowing the Italian team to establish itself among the leading contenders.
However, Charles Leclerc encountered an issue during FP1 that reportedly raised concerns about the car’s reliability. According to the AutoRacer analysis, Ferrari engineers subsequently adjusted the setup to reduce the risk of a failure, accepting a loss of outright performance in return for greater protection.
That compromise would help account for the SF-26 becoming progressively less responsive as the weekend developed. It could also provide further context for Charles Leclerc’s concerns about Ferrari’s inconsistent Hungary performance, although the precise nature of the suspected reliability problem has not been officially disclosed.
Engine power may not explain Ferrari’s performance loss
The reconstruction also offers a different perspective on one of the explanations discussed after qualifying. Charles Leclerc suggested that Mercedes and Red Bull appeared to have increased their power-unit output significantly between Friday practice and Saturday’s competitive sessions.
However, the available data reportedly showed that Ferrari was already losing top speed on Friday. On that basis, the analysis concluded that power-unit management was unlikely to have been the principal reason for the Scuderia’s decline. The setup modifications made to protect reliability were instead identified as the more significant factor.
Ferrari’s aerodynamic configuration had already placed particular demands on straight-line performance during the weekend. A separate assessment of the team’s high-downforce rear wing at the Hungaroring highlighted the difficult compromise between producing grip through the corners and limiting drag on the straights.
How the setup compromise changed the SF-26’s handling
The reported effect of the changes was especially visible in the car’s behaviour around the lap. Ferrari retained a meaningful advantage only in the third sector, described as the circuit’s most technical section, but lost competitiveness through the middle part of the lap.
Those corners demanded sharper responses and a more agile car, qualities the SF-26 appeared less able to provide after the setup revision. The underlying potential had not necessarily disappeared, but Ferrari could no longer exploit it consistently across the entire lap.
For the engineers, the decision would have involved balancing two competing priorities. Maintaining Friday’s more aggressive configuration may have offered greater performance, but it could also have exposed the car to the reliability risk detected on Charles Leclerc’s side of the garage. The revised setup offered protection at the cost of some of the speed required to fight at the front.
Lewis Hamilton may have had the pace to challenge for pole
AutoRacer’s analysis suggested that Ferrari could realistically have challenged for pole position without the reliability-related setup changes. Lewis Hamilton, in particular, may have been capable of erasing his narrow deficit to Lando Norris with a clean final run in Q3.
That assessment reinforces the impression that Ferrari possessed the fundamental pace required to compete for the leading positions in Hungary. Lewis Hamilton later maintained that the team had been capable of winning, an assessment explored in his account of Ferrari’s missed Hungarian Grand Prix opportunity.
Nevertheless, the proposed link between Charles Leclerc’s FP1 issue, the subsequent setup alterations and Ferrari’s loss of performance remains a technical reconstruction based on observations and data analysis. Official confirmation from Maranello is still awaited, leaving the exact cause of the SF-26’s decline unresolved.
