Colton Herta has expressed that moving from Indycar to Formula 1 would present a "difficult decision."
The 24-year-old American, with established ties to Andretti and Cadillac, is frequently discussed as a primary contender to join the planned F1 team set to debut in 2026.
Recently, Mario Andretti, Cadillac F1 advisor and Formula 1 icon, stated to the German news outlet DPA that "the goal from the beginning was to have at least one American driver."
Andretti acknowledged that Herta is "very likely" their leading option.
Speaking at the Indycar media event this week, Herta commented: "If it happens, then that's great but I would have to make a difficult decision.
"It feels like we've been talking about it for half a decade and I'm getting tired of it," he continued. "I just want to drive and concentrate on Indycar and winning the championship this year. If something comes out of that, then I'd have to think about it.
"All my friends and family are here in America so it would be a big decision."
A further challenge for Herta would be securing the necessary points under the FIA's super license system to qualify for F1. "I think the answer to that is that I didn't even know how the system works," he smiled. "If it happens, that's great. And if it doesn't, then poor me.
"Then I'll be stuck racing in Indycar," he said with another grin. "I'll be fine either way."
Meanwhile, Mario Andretti confirmed the current strategy includes pairing Cadillac F1's American driver with a more seasoned competitor.
"Many drivers are being considered. We are keeping all options open," the 84-year-old told DPA.
"It definitely makes sense to put an experienced driver alongside that American driver."
Discussing potential candidates, Andretti added: "Suddenly, someone could become available that we would have never thought of."
