Cadillac Confirms Colton Herta's F1 Practice Debut Date

Cadillac has confirmed that its test driver, IndyCar star Colton Herta, will make his official Formula 1 weekend debut during a practice session at the Spanish Grand Prix in June. The announcement follows Herta's decision to forgo a wildly ambitious plan to compete in both the Indy 500 and an F2 race in Montreal on the same day, choosing instead to focus fully on his primary 2026 duties in Formula 2 and his development role with the F1 team.

Why it matters:

For Herta, long considered one of America's top prospects for F1, these FP1 sessions represent a critical, hands-on step into the pinnacle of motorsport. For the new Cadillac team, it's a structured opportunity to evaluate a talented driver within the intense environment of a Grand Prix weekend, gathering valuable data and integrating him further into their long-term development pathway.

The Details:

• Debut Schedule: Herta's first appearance in an official F1 session will be during Free Practice 1 at the Circuit de Barcelona-Catalunya in June. He is scheduled to complete a total of four FP1 sessions for Cadillac across the 2026 season.
• The Sacrificed Double-Header: The 26-year-old revealed he had explored the logistically staggering idea of racing in the Indy 500 and an F2 event in Montreal on the same weekend—a plan made possible by revised F2 calendars but ultimately deemed unrealistic.
  • Herta cited the importance of 'Carb Day' at Indianapolis and the clear priority of his F2 and Cadillac commitments as the main reasons for shelving the idea.
• Current Focus: Herta is fully committed to his Formula 2 campaign with Campos Racing, where he has already scored points with a seventh-place finish in the season opener in Australia. He described the opportunity to race in Miami and Montreal as an unexpected but welcome bonus.
• Team Perspective: Cadillac Team Principal Graeme Lowdon framed the FP1 runs as a "natural next step" in Herta's test driver role, praising his strong start in F2 and his proven talent from IndyCar.
• Personal Sentiment: While dedicated to his F1 path, Herta admitted it is difficult to watch IndyCar races from the sidelines after six full seasons, calling it a fun series to drive in but acknowledging that a one-off return could potentially hinder his primary goals.

What's Next:

Herta's immediate focus remains on continuing his adaptation in Formula 2 and contributing to Cadillac's simulator program. His performance in the Barcelona FP1 session will be his first real-world test with the team during a Grand Prix weekend, offering a tangible benchmark for his progress and potential future within the Cadillac F1 project. The structured practice appearances are designed to accelerate his learning curve as he balances the dual challenge of a competitive F2 season and the demands of Formula 1.
