Herta's Mexico FP1 Run Hinges on One Disputed Super Licence Point

Colton Herta goes to Mexico City on Friday with a maths problem strapped to his car. Cadillac has confirmed the American will replace Valtteri Bottas in the opening practice session at the Mexican Grand Prix, his fifth Formula 1 practice outing of the season, and the stated purpose is a single super licence point. The catch is that nobody outside the FIA can say for certain whether that point finishes the job, because Cadillac and the independent record disagree by one point about where Herta stands. If Cadillac is right, 24 laps on Friday makes him eligible. If the documented count is right, 24 laps leaves him exactly where the argument started: one point short.

What has Cadillac actually confirmed?

A fifth practice outing, and nothing more. Herta will take over Bottas’s car for Friday’s one-hour opening session at the Autodromo Hermanos Rodriguez, before Bottas returns for the second session, RacingNews365 reports. It extends a programme that was originally four sessions: Barcelona, Hungary, Monza and Austin. Herta has now driven in all five of Cadillac’s practice sessions this season, and the Mexico assignment was confirmed in the team’s official race preview.

Herta welcomed the extra outing in Cadillac’s announcement. “Every opportunity to get behind the wheel with the team is valuable, and I’m looking forward to being back in the car in Mexico,” he said. “It’s a great chance to keep learning, build my experience in Formula 1 on a new circuit and contribute to the team’s work across the weekend.” The quote is routine. The arithmetic behind it is not.

How many points does Herta actually have?

Thirty-nine, says Cadillac. Thirty-eight, says the documented record. The gap is the whole story.

RacingNews365 reports that, according to the team, Herta moved to 39 points with his practice outing at last week’s United States Grand Prix, with 40 required to earn the licence to potentially race in Formula 1. A team spokesman told the outlet it would be “remiss” of Cadillac not to give him an opportunity to finally achieve the super licence he has long worked for.

Grande Premio, working from the publicly documented results, reaches 38. Its breakdown credits Herta’s IndyCar championship finishes with 35 points: one for tenth in 2023, 30 for second in 2024 and four for seventh in 2025. Three practice appearances that met the mileage requirement add three more. That is 38, and the outlet notes that when Cadillac’s spokesperson was asked where the additional point came from, no explanation was provided. Neither calculation, Grande Premio stresses, should be presented as an individually certified FIA total. Only confirmation under the FIA’s rules can resolve the discrepancy, which is why Friday’s session is a test with two possible answers.

Why did the Monza outing not count?

Because five laps is not a practice programme. Herta’s Italian Grand Prix appearance in place of Sergio Perez was cut short by a hydraulic failure after five laps, about 25km, RacingNews365 reports. The minimum for an eligible practice appearance is 100km, so the session earned no point despite Herta taking part. Cadillac identified the problem and told him to stop, and the car could not be recovered in time to resume.

That failure is why Mexico matters so much. Had Monza run its course, the argument about 38 versus 39 might never have existed. Instead, a technical failure turned a routine development outing into a season-long points chase, and Herta has spent the rest of the year making up a point he lost through no fault of his driving. The setback also explains the timing pressure: Grande Premio reports that Herta is approaching the end of the period in which his 2024 IndyCar result, worth 30 points, contributes to his eligibility, so 2026 is the year to finish this, not next year.

What exactly must Herta do on Friday?

Complete 24 laps. The circuit measures 4.304km, so 23 laps covers 98.992km, just short of the 100km threshold, while 24 laps covers 103.296km. The session runs for one hour, starting at 12:30pm local time in Mexico City, 11:30am Pacific, and the altitude makes the mileage harder than the number suggests: the circuit sits about 2,240 metres above sea level, where thinner air affects turbocharging, cooling and aerodynamic performance.

The table below is the whole weekend in miniature. On Cadillac’s count, Friday is the finish line. On the documented count, it is another staging post.

If Herta completes fewer than 24 laps, for any reason, neither count moves, and he will need another qualifying practice appearance that is not currently scheduled. A repeat of Monza, in other words, would end the chase for this season.

Does this mean Herta replaces Bottas in 2027?

No, and the distinction matters more than the points. Grande Premio states it plainly: super licence eligibility and selection for a race seat are two separate decisions. Reaching 40 points would make Herta eligible to apply for the licence, subject to the remaining requirements. It would not oblige Cadillac to replace Bottas or Perez, and Herta taking Bottas’s car in Mexico does not establish that the Finn has been selected to leave.

That said, the driver market around Cadillac is genuinely unsettled. Team boss Marcin Budkowski did not shut down a potential change in the driver line-up when questioned in Austin, RacingNews365 reports, and a podcast rumour reported by Crash.net had already suggested Cadillac might slot Herta into an extra practice session precisely to chase the final point. Cadillac has also just extended Sergio Perez through 2029 ahead of his 300th start at his home race, which secures one seat and sharpens the question over the other. Bottas, for his part, has said publicly that he knows his situation and that it is all good, which is what a driver under pressure usually says. The Mexico session will not answer the seat question, but it will decide whether Herta is even eligible to be part of it.

Why has this taken Herta so long?

Because the super licence system has blocked him before. A potential move to Formula 1 in 2022 was stopped when the FIA declined to grant Herta a waiver to qualify without the necessary 40 points in a three-year period, RacingNews365 reports. He had won nine IndyCar races by then, but championship results alone did not carry him over the threshold. He left an established IndyCar career to pursue Formula 1 with the Cadillac project, moved to Formula 2 for 2026 in search of another route to the points, and has had a difficult campaign there, which leaves practice appearances as his most reliable remaining route.

The irony of the Mexico weekend is that Herta is not the only driver sitting out Friday’s first session. Mercedes must give Frederik Vesti a run in George Russell’s car under the rookie practice rules, and Alpine, Williams, Audi and Aston Martin all have substitutes in for their regulars too, taking the total to six. For those teams, Friday is a regulatory chore. For Herta, it is the difference between eligible and not, depending on whose maths the FIA accepts. He will know by Friday afternoon whether he completed the laps. He may have to wait longer to find out whether they counted, and the FIA has shown this season it is willing to own its errors in public, as when it admitted human error gave some cars extra power in Singapore sprint qualifying.

What happens next?

Friday’s session, then the wait. If Herta completes 24 laps, Cadillac will present him as having reached 40 points, and the documented count will say 39. The FIA’s recognised total, when it emerges, settles it. If he falls short of the mileage, the chase pauses with no further scheduled practice outing in the current programme. Either way, the 2027 line-up decision runs on its own timetable, and the title arithmetic that dominates the Mexico weekend will rightly take the headlines on Sunday, alongside Perez’s 300th start at his home race. Herta’s story is smaller and stranger: a driver who may or may not have qualified for Formula 1 by the end of Friday, depending on a single point nobody can publicly account for.
