Colton Herta to Make F1 Debut with Cadillac at Spanish Grand Prix

Colton Herta is set to make his official Formula 1 debut this weekend at the Spanish Grand Prix. Cadillac has confirmed that the 26-year-old American will step into Sergio Perez's seat for the opening practice session (FP1) at the Circuit de Barcelona-Catalunya.

Why it matters:

Herta's transition from a dominant IndyCar career to Formula 2—and now to a potential F1 seat—represents a high-stakes gamble to break the American drought in the sport. His performance this weekend serves as a critical litmus test for Cadillac as they evaluate their driver trajectory and long-term strategy for the 2026 season.

The details:

• FP1 Requirement: Herta's appearance fulfills one of the four mandatory young driver sessions required by F1 regulations, with Barcelona being a preferred venue due to its familiarity to the grid.
• Dual Program: The weekend will be a grueling test of endurance for Herta, as he is simultaneously competing in Formula 2 with HiTech.
• Preparation: To bridge the gap, Herta has undergone extensive simulator work in Charlotte and has been shadowing the team's operations at Silverstone to accelerate his adaptation to F1 procedures.
• The Bottas Saga: Despite the debut, Cadillac team principal Graeme Lowdon and Valtteri Bottas have vehemently dismissed rumors that Herta is slated to replace Bottas. Lowdon labeled the speculation "fiction" and attributed the noise to "click-bait headlines."

What's next:

While the team officially denies any immediate seat changes, all eyes will be on Herta's telemetry and feedback during Friday's session. A clean, competitive showing in Barcelona could validate the external rumors and put significant pressure on the current driver lineup as the 2026 season progresses.
