Piastri loses pace: the pattern is clear
Oscar Piastri qualified significantly slower than teammate Lando Norris in Mexico. His fastest lap was 0.588s slower than Norris'. Due to a grid penalty from Carlos Sainz, Piastri is now seventh on the grid. That is the first time since April that he is in danger of losing his championship lead.
The striking thing is that this was not an isolated error in Q3. The problem played out all weekend. In both free practice sessions, he was about six tenths behind Norris. The differences in Q1 and Q2 were 0.259 s and 0.485 s. Piastri was also slower than his teammate in the US last week.
Possible causes at a glance
There are several explanations that could explain the loss of pace. The team and Piastri himself cite several options.
- Undetected damage to car after crash in Austin.
- Technical parts that work slightly differently on his car.
- Difference in driving style and how it suits low grip conditions.
Team check: car seems fine
McLaren says based on data and checks that there is no obvious mechanical problem. The team stresses that parts are rotated regularly and that there is no evidence of a defective chassis. They would rather change floor or front wing than replace the monocoque.
Yet Piastri himself did not rule out damage altogether. He said the car generally felt normal, but often had less grip than Norris.
Driving style and low grip conditions
According to the team, the root of the problem lies with the driving style. Norris appears to perform better in sliding, low-grip conditions. Piastri, on the other hand, is stronger when there is a lot of grip. Those differences were visible in Austin and in Mexico.
A key issue is brake usage. In Mexico and Austin, Norris made more gains in heavy braking zones. His braking strategy and way of controlling the rear tyres gave him an advantage. Piastri experimented with braking points and the length of his braking zones, but could not always match that advantage.
Where did Piastri lose time?
- Turn 1: lost about 0.05s at the first apex due to slightly later braking.
- Turn 2 and the next right/left combination: lost extra time and speed.
- Turn 4-6: previously a weak spot, but improved in Q3.
- Turns 7-11 (the fast sweepers): here Norris built much of his lead, nearly 0.45 s by Turn 12.
On exiting Turn 10/11 and through the stadium complex, Piastri lost time again. Managing the backline temperature seemed to play a part. In the analysis, he himself said it felt like ‘losing a bit everywhere’ rather than one clear trouble spot.
Long-term pace and race image
The problem was not limited to one fast lap. Even in long runs, Piastri looked slower than Norris. That makes the race tricky. Mexico is expected to be a processional race with a strategy around one pit stop. In such a race, overtaking is difficult. Therefore, Sunday will be mainly damage control for Piastri.
Yet it is not the end. Piastri has shown at several races this season that he can adjust and learn quickly. The team expects him to perform at his usual level again at Interlagos.
Conclusion
In summary, there is no direct evidence of a technical defect. The data support that the car is functioning. The biggest chance is that the combination of low grip and a driving style that is less suited to it cost Piastri dearly. It is a learning process for him. For Sunday, it's all about limited loss avoidance. After that, he will get another chance to address the problem.
