How Missing Centimetres Triggered Gasly’s Shocking F1 Penalty Reversal
Highlights
- Pierre Gasly’s pitlane speeding penalties overturned after distance review.
- Monaco pitlane’s curved layout caused incorrect speed measurement.
- Shortest distance was 77 cm less than official timing measurement.
- Gasly’s recalculated speeds were below the 60 km/h limit.
- Other drivers’ penalties stayed due to timing and appeal rules.
- Red Bull and McLaren plan appeals against FIA decision.
Pierre Gasly is reinstated to third in Monaco after stewards overturn his pitlane speeding penalties following a post-event distance review.
The call comes days after the race and removes a podium from Isack Hadjar, who had inherited third for Red Bull.
The dispute centers on Monaco’s curved pitlane. Speed is distance over time; the first timing zone was set at 2,692 cm, but the shortest traversable line measured 2,615 cm.
That 77 cm gap inflated calculated speeds for identical times, creating false positives around the 60 km/h limit in the pit entry zone.
The stewards granted a review when new scan data emerged. Barrier tweaks since 2025 likely opened a tighter line that routine checks missed.
FIA’s Nikolas Tombazis accepted the legacy method might not fit the updated layout. Formula One Management followed 2025 procedures but acknowledged the discrepancy.
Key discrepancy: 2,692 cm official distance vs 2,615 cm shortest line — a 77 cm error that skewed speeds.
Recalculation using the 2,615 cm minimum and Gasly’s roughly 1.6s transits produced 58.7 and 58.8 km/h, both inside the limit.
Although a driver cannot always trace the absolute shortest path, the regulations reference minimum distance, so the stewards used that line as the comparator.
Alternative evidence from onboard sensors or manual checks was set aside over calibration concerns. The panel instead reached “comfortable satisfaction” that the system overstated speed.
Stewards reached “comfortable satisfaction” that Gasly stayed within the 60 km/h limit despite initial timing data.
Several drivers registered the same 60.1 km/h reading in that zone during the race, which raised doubts, but race control initially stood by the data.
The measurement issue surfaced only after Alpine compiled a case with FOM’s support, as outlined in the Alpine Grand Prix review.
Penalties served in-race for Lewis Hamilton, George Russell, Franco Colapinto, and Oscar Piastri remain, as appeal windows closed and rules prevent undoing executed sanctions.
Other drivers’ penalties stand because they were served in-race and outside the window for appeal.
That reality shaped the final order; Russell and Piastri would have finished ahead of Gasly without their penalties.
Red Bull and McLaren plan appeals. McLaren also aims to keep Piastri’s sanction, arguing the weekend’s timing baseline was consistent and understood.
Teams routinely coach drivers to the known system, imperfections included, but the rules set a limit without mandating a single proof source, enabling this reassessment.
Context around Alpine’s operations, including recent Gasly-Alpine radio silence, and governance themes explored in the Alpine controversial penalty review frame the wider fallout.
The episode shows how centimetres and methodology can swing podiums and should accelerate geometry-aware pitlane measurement standards for curved entries.

A Decision Made by 77 Centimetres
Gasly’s podium fate hung on the difference between Monaco’s curved pitlane and an outdated measurement — the 77 cm that changed it all.

All because 77cm decided the truth of speeding.
In F1, precision isn’t just tenths of a second—it can be the tiny curve of a pitlane.
A missed measurement. A podium gained, and lost. Proving sometimes, Formula 1 is decided by less than a meter.
