According to racing legend and Cadillac advisor Mario Andretti, American IndyCar driver Colton Herta is still the odds-on favorite to be called up for driving duty when the team hits the Formula 1 grid for the 2026 season. And he says the General-Motors-backed squad is looking to finalize its driver roster soon.
"Looking back at the way Colton has trained from the very beginning of his young career — as you know, he started in Formula 3 and so on with the likes of Lando Norris, and he's done some F1 testing," Andretti said. "Zak Brown gave him a good test at Portimao in Portugal. You should see the report that we got from [team principal] Andrea Stella. And Andrea is an individual that says it like it is — so again, [Herta's] a great candidate. And all of this has to be proven, of course, but going in, he's a good bet, in my opinion."
