Colton Herta is returning to Europe as the 25-year-old IndyCar Series driver from California was named as test driver for Cadillac Formula 1 as it begins its maiden season in 2026.
The nine-time NTT IndyCar Series race winner just concluded the 2025 IndyCar season seventh in points.
“I’m incredibly excited to be joining the Cadillac Formula 1 Team as a Test Driver. This is a dream opportunity, and one I’ve been working towards for a long time,” Herta said. “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 towards that goal. For now, my focus is on giving everything I can to Cadillac F1, helping build a competitive team.”
Herta Returns To Europe
For Herta, 25, the 2026 season will mark a return to the European racing ranks, as the second-generation racer – the son of IndyCar and Champ Car driver Bryan Herta – made his European racing debut in 2015. Over a two-year period, he secured four victories, six podium finishes and five pole positions in the Euroformula Open Championship and went on to compete in six British F3 events, earning three podium finishes including a victory at Brands Hatch before returning to America in 2017.
Coming off his seventh IndyCar season, Herta has recorded nine wins, 16 pole positions, and led over 1,000 laps in his 116 career starts. He also holds the title of youngest driver to win an IndyCar Series race and pole position, a feat he achieved in 2019 at the Circuit of the Americas – home of the F1 United States Grand Prix. In addition to a successful INDYCAR career, Herta has scored multiple IMSA WeatherTech Sportscar Championship class wins at the Rolex 24 at Daytona (2019 and 2022) and an overall win at the 12 Hours of Sebring in 2024.
Transitioning into a new role within TWG Motorsports, Herta is the first Test Driver named by the Cadillac Formula 1® Team, following the announcement last month that experienced F1 duo Valtteri Bottas and Sergio ‘Checo’ Perez will form the team’s first-ever race driver line-up during its debut season next year. Announcements on Herta’s 2026 racing program will be made in due course.
