Andretti Global IndyCar driver Colton Herta has been named the test driver for Cadillac F1 as they make their Formula 1 debut in 2026.Herta will also drive in full time in F2 on a team yet to be named.

Herta drove seven seasons in IndyCar starting in 2018 with Harding-Steinbrenner and then Andretti. He is the youngest driver to win an IndyCar race, winning the race at COTA in 2019. His last win came at Nashville in 2024.

Herta told IndyCar.com, “I’m incredibly excited to be joining the Cadillac Formula 1 Team as a test driver,” Herta said. “This is a dream opportunity, and one I’ve been working toward for a long time. To be part of Cadillac F1’s entry at such a pivotal time is something I couldn’t pass up.

“My dream has always been to race in Formula 1, and I see this move as a huge step toward that goal. For now, my focus is on giving everything I can to Cadillac F1, helping build a competitive team.”

Herta finished the 2025 IndyCar season seventh in points. He won pols at Detroit and Toronto.

For his career, Herta won nine times, earned 16 poles, and led more than 1,000 laps.

It hurts for the series to lose a 25 year old driver, especially one I am a fan of. It is hard to believe he has driven for seven years.

Andretti Global has not named a replacement for 26 yet, but I expect an announcement soon. The new driver will expected to join the

team will make the organization more powerful.
