- Racing Bulls driver Liam Lawson has been disqualified from Qualifying for the Mexico City Grand Prix due to an MGU-K technical infringement.
- Lawson originally set the eighth-fastest time in Qualifying before an investigation found his car breached regulated power reduction rates at the end of his fastest Q2 lap.
- Despite Racing Bulls self-disclosing the issue and noting no performance advantage was gained, stewards adhered to strict technical precedents and demoted Lawson to the back of the grid.
Liam Lawson Stripped of Mexico City GP Qualifying Result
Racing Bulls driver Liam Lawson has been disqualified from Qualifying for the Mexico City Grand Prix after his car was found to have committed a technical breach. The New Zealand racer had enjoyed a strong Saturday performance at the Autodromo Hermanos Rodriguez, posting the eighth-quickest time to finish ahead of his Racing Bulls teammate, Arvid Lindblad.
Prior to the technical ruling, Lawson had already been facing a slight drop down the starting order. The stewards had previously assessed him a one-place grid penalty stemming from an incident involving Red Bull Racing driver Max Verstappen during Free Practice 2 (FP2). While that earlier sanction would have slotted Lawson into ninth position for Sunday’s Grand Prix, the post-session technical ruling erased his qualifying times altogether and relegated him to the rear of the field.
Technical Infringement and the Stewards’ Ruling
The post-qualifying sanction arose after technical officials examined the data from Lawson’s car following the second stage of the session. Official notes indicated that Lawson was in breach of the minimum MGU-K power requirement just after crossing the line on his fastest lap in Q2
.
A formal report issued by the FIA Technical Delegate elaborated on the mechanical issue, stating: The driver maximum power demand and the electrical DC power of the ERS-K were reduced at greater rates than what is permitted by the Regulations.
Following this report, Lawson and representatives from Racing Bulls were summoned to face the stewards, alongside the Single Seater Sporting Director and personnel from the FIA Technical team. During the hearing, telemetry confirmed the technical deviation.
In their official decision document, the stewards outlined the sequence of events: Evidence submitted, which was accepted by all parties present, showed that after the control line at the end of his fastest lap in Q2, the driver did not lift off the power immediately,
the panel explained. This resulted in the rate of reduction of MGU-K deployment required to achieve the regulated ‘step down’, not being achieved.
The document further addressed the team’s defense, emphasizing the unyielding nature of Formula 1’s technical rulebook: The team argued that this did not provide any performance advantage however it is clear that non-compliance with the Technical Regulations is not excused if no performance advantage is gained. Further, these regulations require that a car must comply with them at all times during an event.
The stewards also recognized that the team brought the issue forward voluntarily, but maintained that the regulations left no alternative option: The stewards note in particular that the team self-disclosed the breach however there are a multitude of precedents that require us, despite all mitigating circumstances, to impose a penalty of disqualfication where a car does not comply with the Technical Regulations.
Why This Matters
Formula 1 technical regulations are treated as absolute boundaries rather than flexible guidelines. As reaffirmed by the stewards in Mexico City, intent and competitive advantage do not factor into technical legality verdicts. Even when an issue occurs after crossing the finish line and provides no performance benefit, any failure to adhere to the precise power curve and energy recovery limits set by the FIA results in mandatory exclusion from that competitive phase.
For Racing Bulls, Lawson’s disqualification transforms what was a promising qualifying result into a major operational setback. Instead of launching from the top ten and fighting for vital constructors’ championship points from ninth place, Lawson will be forced to line up at the back of the grid, requiring a recovery drive on race day.

Why was Liam Lawson disqualified from Qualifying?
Lawson was disqualified because his Racing Bulls challenger breached the technical regulations governing the rate of reduction of MGU-K deployment at the conclusion of his fastest lap in Q2.
Did the technical issue give Racing Bulls an unfair advantage?
Racing Bulls argued that the infringement provided no performance advantage. However, FIA Technical Regulations state that cars must comply at all times, and established precedent requires disqualification regardless of whether an advantage was gained.
