Cadillac’s search for the ideal driver line-up ahead of its second Formula 1 season is becoming increasingly interesting, with Colton Herta emerging as a serious contender for a race seat in 2027. Sergio Perez has now offered a positive assessment of the American’s progress, suggesting that Cadillac is beginning to see more of his potential as he gains experience with the team.
Herta is currently serving as Cadillac’s test driver while attempting to secure the FIA Super Licence required to compete in Formula 1. His potential promotion could create a major opportunity for the American, but it would also put Valtteri Bottas under pressure as uncertainty continues surrounding the second seat.
Perez, who has recently signed a new multi-year agreement keeping him at Cadillac for at least another three years, believes Herta is contributing valuable information to the team’s development. However, the Mexican made it clear that selecting his future teammate is not his responsibility.
PEREZ DELIVERS POSITIVE VERDICT ON HERTA
Speaking ahead of his home Mexican Grand Prix, Perez described Herta’s work within Cadillac as encouraging, particularly his technical feedback and growing understanding of the car.
The former Red Bull driver acknowledged that Friday practice sessions are not always the best opportunity for a reserve or test driver to demonstrate their full potential. Limited running time, unfamiliar conditions and the need to follow a team’s testing programme can make it difficult to judge a driver’s outright speed.
However, Herta has been spending more time in the simulator and gaining additional experience behind the wheel. Perez believes that progress is allowing Cadillac to develop a clearer understanding of what the American can offer.
Perez also praised Herta’s feedback, an important quality for a new manufacturer trying to establish itself in Formula 1. Cadillac needs drivers who can help engineers understand the car, identify weaknesses and accelerate development.
For a team still building its foundations, technical contribution could be just as important as outright speed when evaluating a potential long-term driver.
VALTTERI BOTTAS FACES A SERIOUS CHALLENGE
While Herta’s reputation within Cadillac appears to be growing, Bottas has not been ruled out of the team’s plans.
According to PlanetF1’s report, continuing with the experienced Finnish driver remains Cadillac’s preference at present, despite the competition for his position. Bottas has considerable Formula 1 experience, including race victories and years of working with leading teams.
Perez also defended his current teammate, pointing out that Bottas has suffered misfortune in several races. He specifically highlighted the Finnish driver’s performance at the United States Grand Prix, where he believes Bottas demonstrated strong pace.
This is an important part of the discussion because Cadillac must balance future potential with the immediate demands of building a competitive team.
Bottas offers experience, technical understanding and familiarity with the demands of Formula 1. Herta, meanwhile, represents a younger option with a different racing background and the possibility of becoming an important part of Cadillac’s long-term project.
The decision will not necessarily come down to one driver’s speed alone. Consistency, development contribution, adaptability and the team’s wider objectives will all matter.
HERTA’S SUPER LICENCE COULD CHANGE EVERYTHING
One of the biggest obstacles standing between Herta and a Formula 1 race seat has been his FIA Super Licence eligibility.
The American is scheduled to receive an additional FP1 outing at the Mexican Grand Prix. If he completes the required 100 kilometres during the session, he is expected to secure the final point needed for his Super Licence.
That would remove a significant administrative barrier to his promotion, although it would not automatically guarantee him a place in Cadillac’s 2027 line-up.
Herta’s transition to Formula 2 in 2026 has also presented challenges. He has struggled to produce the results expected of him, raising questions about how quickly he can adapt to the European single-seater environment.
However, his previous success in IndyCar and his experience with Cadillac’s development programme remain relevant considerations.
Formula 1 is a different challenge, and the team will need convincing evidence that he can adapt to its technical demands, race procedures and competitive environment.
CADILLAC’S NEXT THREE MONTHS COULD BE CRUCIAL
Perez believes Cadillac is entering an important development period, with the next three or four months expected to play a major role in its preparations.
That makes the second driver decision particularly significant. Cadillac cannot afford to make a choice based solely on popularity or nationality. It needs a driver pairing capable of helping the organisation progress quickly.
Perez also confirmed that he does not want to influence the selection process. He trusts team principal Marcin Budkowski to evaluate the available information and decide which driver is best suited to the team’s future.
This approach is sensible. Although a driver relationship matters, the final decision must serve the organisation rather than simply satisfy the preferences of one side of the garage.
WILL CADILLAC CHOOSE HERTA OR KEEP BOTTAS?
The battle between Herta and Bottas presents Cadillac with two very different options.
Keeping Bottas would provide stability and preserve an experienced partnership with Perez. Promoting Herta would offer the team an opportunity to invest in a driver it could potentially develop over several seasons.
There is also a commercial dimension to Herta’s potential promotion. As an American driver joining an American-backed manufacturer, he could attract additional attention from the United States market. However, commercial appeal cannot replace the need for competitive performance.
For now, Perez’s comments suggest that Herta is making progress and earning credibility within the organisation. They do not, however, confirm that he has been selected.
Bottas remains a serious candidate, and Cadillac’s final decision will reveal whether the team values immediate experience or believes Herta is ready to become part of its long-term Formula 1 project.
One thing is certain: with Perez already secured, the remaining seat could become one of the most closely watched driver decisions ahead of the 2027 season.
