Charles Leclerc has explained why Ferrari’s promising pace failed to translate into a stronger qualifying result at the 2026 United States Grand Prix, identifying a combination of power unit limitations, tyre-temperature sensitivity and balance problems that left the SF-26 operating on a knife-edge in Q3. Although Ferrari had the potential to achieve more in Austin, the Monegasque driver was unable to improve on his Q2 lap time during the decisive final session, leaving him particularly frustrated at a missed opportunity.
While Ferrari’s difficulty in reaching the ideal tyre operating window can often become an advantage during races, it remains a significant limitation in qualifying. The problem is particularly costly when combined with the SF-26’s familiar engine deficit, which becomes more pronounced when rival teams increase their power unit output for their fastest laps.
Why Ferrari’s Q3 qualifying weakness continues to hurt Charles Leclerc
It is no secret that qualifying has been something of an Achilles’ heel for Ferrari in recent years, even more so during the 2026 Formula 1 season. When teams switch to more aggressive engine settings, the power deficit affecting the SF-26 becomes more evident. However, this is not the only factor preventing Ferrari from maximising its performance over a single lap.
When Ferrari needs to extract the final few tenths in Q3, its rivals often find it easier to make the necessary improvement between the final two qualifying sessions. The difference is not simply attributable to engine performance, but also to how effectively each car can exploit its tyres and balance at the limit.
One particular statistic from Austin illustrates this difficulty especially clearly. Charles Leclerc failed to improve between Q2 and Q3, meaning his fastest qualifying lap actually came in the second session rather than the final one, when drivers would normally be expected to push their cars to the absolute limit.
As previously analysed in September, Ferrari gains approximately two tenths less than Mercedes on average when progressing from Q2 to Q3. That difference emerged again at the United States Grand Prix, even allowing for Andrea Kimi Antonelli’s unsuccessful final attempt. The progression between qualifying sessions and the sector-time differences can also be explored through the ScuderiaFans F1 Qualifying Pace & Sector Comparison.
Ferrari loses more than 10 km/h to Mercedes on COTA’s long straight
The difference in power unit performance compared with Mercedes and Red Bull undoubtedly plays a major role. On the long straight at the Circuit of The Americas, Ferrari loses more than 10 km/h to the Mercedes W17, partly because of the SF-26’s higher aerodynamic drag. That deficit alone is worth approximately two tenths of a second.
Ferrari’s straight-line disadvantage had already emerged during its opening practice analysis in Austin, despite the improvements in downforce offered by the car’s aerodynamic configuration.
However, Charles Leclerc believes the power unit deficit was not the only issue that emerged during qualifying. During Friday’s practice sessions, the time Ferrari gained through the more technical sections of the circuit had been sufficient to compensate for what the SF-26 lost on the straights. That balance changed in qualifying, and the difference cannot be explained solely by rival teams using more aggressive engine settings.
“The engine deficit is there, you can see it immediately in the data. We were able to make the difference in the corners, but as soon as we’re not in the right tyre window, we lose a lot, and that’s what happened in Q3. It made me very angry because it hadn’t happened until Q3, when we have to put everything together,” Charles Leclerc explained to Sky during his post-qualifying interview, highlighting the sensitivity of Ferrari’s SF-26.
“The track cooled down, only very slightly, perhaps 1°C, but for me that made a huge difference. Between Q2 and Q3, we never managed to get the tyres into the right operating window.”
Lewis Hamilton also highlighted the importance of tyre preparation. According to the seven-time world champion, his out-lap before the first qualifying attempt was actually too quick, which subsequently compromised his ability to manage tyre temperatures during the flying lap.
Why the Ferrari SF-26 becomes so difficult to drive at the limit
To compensate for its engine deficit, Ferrari clearly needs to make the difference through the corners. However, particularly over a single qualifying lap rather than a race distance, the SF-26 has an extremely narrow operating window when its drivers attempt to extract the final tenth of performance.
Charles Leclerc and Lewis Hamilton are therefore required to push closer to the limit than their rivals to recover the time lost elsewhere around the circuit. That leaves very little margin for error when preparing the tyres and finding the ideal car set-up, a difficulty that was also evident with Lewis Hamilton in Singapore.
The problem is becoming increasingly significant as the season progresses. Rival teams continue to improve their cars, gradually reducing the advantage Ferrari previously enjoyed in the corners. This forces its drivers to push even harder in pursuit of the final hundredths of a second, increasing the likelihood of mistakes.
When the tyres are outside their ideal operating window, certain limitations in the car’s balance also become more apparent. In Austin, the decision to increase front-wing load ultimately failed to deliver the desired result.
These difficulties are particularly frustrating given the potential Ferrari had demonstrated earlier in the weekend, including Charles Leclerc’s encouraging FP2 performance.
Charles Leclerc believes Ferrari missed an opportunity to start on the front row
Although these problems are not new, Charles Leclerc felt an additional sense of regret after qualifying because he believed Ferrari had the potential to achieve a better result. Pole position might still have been beyond reach, but a place on the front row alongside Andrea Kimi Antonelli was probably attainable, particularly given the unexpected difficulties encountered by Max Verstappen.
Starting from the front row, and especially ahead of Max Verstappen, would have been crucial. It could have given Ferrari an entirely different outlook for the race, whereas Charles Leclerc now faces the prospect of having to recover positions from the opening lap.
“Yes, it’s very disappointing because I think there have been other weekends where we’ve been strong in free practice, but then when we got to qualifying it became very clear that the others had much more straight-line speed, and it’s really difficult for us to match them.”
“However, I think today was a qualifying session where we had the potential in the car. But the car also includes the tyres and, unfortunately, in Q3 we couldn’t get them into the right operating window. I was already struggling a lot on the out-lap, sliding quite a bit from that point onwards, and that made everything very complicated afterwards.”
For Charles Leclerc, the problem becomes especially evident when attempting to extract every last hundredth of a second from the SF-26.
“I mean, as soon as you get to Q3 and start pushing to gain the last few hundredths, or even two hundredths, in every corner, that’s when perhaps the car’s problems, the balance problems we’re having, become a little more apparent. For us, it’s really a knife-edge situation, and as soon as we go slightly beyond that limit, we lose quite a lot of lap time.”
Could Ferrari’s qualifying tyre problems become an advantage in the race?
The SF-26’s difficulty in bringing its tyres up to temperature quickly has been apparent since the beginning of the season. Finding the correct rhythm during the preparation lap is therefore fundamental to extracting the car’s maximum qualifying performance.
At the same time, what frequently represents a limitation over a single lap can become a strength during a Grand Prix. Ferrari’s ability to control tyre temperatures over longer distances can provide an important advantage during extended stints, particularly on circuits where degradation is significant.
That could prove especially relevant at the Circuit of The Americas, where several teams had already shown high levels of tyre degradation during Friday’s running. The concern has also been highlighted in Pirelli’s assessment of the tyre challenges and potential strategic implications at Austin.
Although Ferrari’s inability to maximise its qualifying performance has left Charles Leclerc disappointed, the characteristics that make the SF-26 difficult to exploit over a single lap could still work in the team’s favour over a race distance. The challenge will be turning that potential advantage into a stronger result after missing the opportunity to start from the front row.
