Audi's Bortoleto Disqualified from Miami Sprint Over Intake Pressure Breach

Key facts

• Gabriel Bortoleto disqualified from Miami Grand Prix Sprint.
• Engine intake air pressure exceeded 4.8 barA limit.
• Violation of FIA Technical Regulation Article C5.3.2.
• Bortoleto finished 11th in the 100-kilometre Sprint.
• Audi team admitted the finding but cited a single-lap temperature spike.
• Nico Hulkenberg failed to start due to a car fire on reconnaissance laps.
• Stewards applied usual penalty of disqualification for technical infringement.

Disqualification After Technical Breach

Gabriel Bortoleto has been excluded from the result of Saturday’s Sprint race at the Miami Grand Prix after a post-race technical inspection found his Audi’s engine intake air pressure exceeded the legal limit. The Brazilian had crossed the line in 11th place, but the disqualification wipes that result from the record. The FIA stewards confirmed that the pressure measured in Bortoleto’s car surpassed the maximum permitted 4.8 barA, breaching Article C5.3.2 of the FIA Formula 1 Technical Regulations. The infringement was flagged by FIA Technical Delegate Jo Bauer during standard post-Sprint checks.

Team Admits Violation, Cites Temperature Spike

In the stewards' hearing, Audi team representatives admitted the technical delegate’s finding was correct. They offered a mitigating explanation: the pressure exceeded the limit for only one lap, when temperatures rose higher than anticipated. Once the team became aware of the issue, they took steps to bring the pressure back into compliance. However, the stewards noted that the regulations require the car to be in compliance “at all times,” and the temporary breach was sufficient to warrant a penalty. The panel stated that while the team’s corrective actions were recognized, the rules are clear.

The Technical Regulation and Measurement

The relevant section of the technical rulebook mandates that engine intake air pressure must be less than 4.8 barA at all times. The pressure is measured by two FIA-approved and sealed devices through which all air destined for combustion must flow. These devices are installed in FIA-approved locations in the engine intake air system downstream of the charge air cooling system. During the post-Sprint checks, the scrutineers found that the pressure in Bortoleto’s Audi exceeded this limit, leading to the referral to the stewards.

A Challenging Sprint for Audi

Bortoleto’s disqualification capped a difficult Sprint for Audi, which had already lost Nico Hulkenberg before the race start. Hulkenberg’s car caught fire during the reconnaissance laps, preventing him from taking the grid. The team therefore ended the Sprint with no points from either driver. The disqualification adds to Audi’s woes in a season where reliability and compliance have been under scrutiny. The team will now focus on the main Grand Prix, hoping to avoid further setbacks.

Stewards' Decision and Precedent

The stewards’ decision document outlined that the usual penalty for a technical infringement is disqualification from the Sprint classification. They emphasized that the car must be compliant at all times, and the temporary nature of the breach did not exempt it from penalty. The panel heard from team representatives and reviewed the technical delegate’s report before reaching their verdict. This ruling reinforces the strict liability principle in F1 technical regulations, where even a momentary non-compliance can result in exclusion. Teams are reminded that they bear full responsibility for their car’s conformity throughout the session.

Outlook for Bortoleto and Audi

Bortoleto will now look ahead to the main Miami Grand Prix, where he will start from a grid position determined by qualifying. The disqualification does not carry over to the main race, but it leaves the driver without points from the Sprint. Audi will need to address the underlying issue that caused the pressure spike to prevent recurrence. The incident also highlights the intense technical scrutiny in Formula 1, where even small deviations can have significant consequences. For Bortoleto, the focus will be on delivering a strong performance in the feature race to put the Sprint disappointment behind him.

The bottom line

• Gabriel Bortoleto disqualified from Miami Sprint for engine intake air pressure exceeding 4.8 barA limit.
• Audi admitted the breach but cited a single-lap temperature spike; stewards applied standard penalty.
• Nico Hulkenberg also failed to start due to a car fire, compounding Audi's difficult Sprint.
• The disqualification underscores F1's strict compliance rules, with no allowance for temporary breaches.
• Bortoleto will compete in the main Grand Prix, seeking to rebound from the Sprint setback.
