Red Bull has been called in front of the stewards in Miami after Isack Hadjar’s RB was found to have failed a post-qualifying legality check — and the Frenchman is now staring down the kind of penalty that turns a solid Saturday into a very long Sunday.
During scrutineering after qualifying for the Miami Grand Prix, the FIA’s technical delegate Jo Bauer reported that Hadjar’s floor was outside the permitted reference volume. Specifically, Bauer noted both the left-hand and right-hand floorboards were protruding by 2mm beyond “RV-FLOOR BOARD”, putting the car in breach of Article C3.5.5 of the Formula 1 Technical Regulation.
“As this is not in compliance with Article C3.5.5 of the Formula 1 Technical Regulation, I am referring this matter to the stewards for their consideration,” Bauer wrote.
In plain terms, that’s not a judgement call about interpretation or a grey-area tweak that can be talked down with a persuasive diagram. It’s a dimensional non-compliance, and those generally end one way: disqualification from the session in which the infringement occurred. The case is scheduled to be heard at 7am on Sunday morning.
Hadjar had qualified ninth, but with the matter already elevated to the stewards as a technical fault, the likely outcome is that his Q3 result is wiped out — leaving him to start from the back.
The irony is that Miami was supposed to be a step forward for Red Bull, not an administrative headache. The team arrived with a busy upgrade package, including a new floor as part of seven changes, and a rear wing configuration that’s already been dubbed the ‘Macarena’. In its FIA submission, Red Bull described the revised floor concept in typically dry but revealing language: “the revised bib geometry accommodates changes to the forward floor structure, then blends with the sidepod to then meet the engine cover. Extracting more load whilst maintaining the downstream flow stability.”
That’s the sort of performance hunt that wins you tenths — but it also tightens the tolerances. Floors live millimetres from legality, and when a new part meets the brutal realities of kerbs, bumps, heat and parc fermé scrutiny, there’s nowhere to hide. Two millimetres might sound trivial from the outside, yet it’s exactly the scale this era of F1 policing operates at.
Hadjar’s car was one of 13 chosen for targeted checks in qualifying, which is when the floor issue was picked up. Max Verstappen’s car was weighed afterwards, but did not go through the same scrutineering process as his team-mate.
For Hadjar, it’s a particularly sour development because his Saturday already sounded like hard work behind the wheel. Even before the stewards’ summons, he’d been candid about a session that never quite came together.
“I just couldn’t put it all together,” he said after qualifying. “I couldn’t take Turn 1. To miss Turn 1, it’s Turn 2 and 3 that are compromised as well.
“It started there, and then you heat up the tyres more, and then you pay the price for the rest of the lap. I’m just struggling with drivability as well.
“It’s a very, very tricky track, very low grip with high track temperature.”
Now that struggle risks being compounded by a Sunday spent fighting through traffic rather than banking points from the top 10. And in a season where Red Bull is clearly leaning into aggressive development — Miami’s floor being the latest example — the stewards’ decision will also be watched closely for what it says about how fine the margins really are on this upgrade direction.
If the car is deemed illegal, it won’t matter whether the protrusion was a one-off, a manufacturing tolerance issue, or something that emerged under load during running. The regulations are blunt on this: the car must comply, all the time. Red Bull will get its right to be heard, but the precedent for dimensional breaches leaves little room for optimism.
For Hadjar, the bigger frustration may be that his first proper Miami statement could end up as a footnote — not for what he did in the cockpit, but for what the FIA found underneath it.
