INDY NXT by Firestone race winner Caio Collet has signed with AJ Foyt Racing for the 2026 NTT INDYCAR SERIES, driving the No. 4 Chevrolet in the entire 17-race season with sponsorship from Combitrans Amazonia.

Collet, 23, from Brazil, finished second in the INDY NXT by Firestone standings in 2025 and won four races during his two seasons in the INDYCAR development series. He earned series Rookie of the Year honors in 2024 after placing third in the standings.

"I’m very happy to join AJ Foyt Racing in the NTT INDYCAR SERIES and thankful to Larry (Foyt, team president) for trusting my skills and giving me this fantastic opportunity," Collet said. "It is a dream come true after years of hard work in developing series since my early go-karting experiences. I’m thankful to all teams and sponsors that helped me through my career, especially Marcelo Camargo from Combitrans Amazonia, that joined our INDY NXT campaign this season and will be with us next year.

“INDYCAR is huge in Brazil, and I’m looking forward to bringing its flag back to a full-time seat in the 2026 season.”

Collet continues a long line of Brazilian drivers in the INDYCAR SERIES, including four-time Indianapolis 500 winner Helio Castroneves and series champions, Indianapolis 500 winners Emerson Fittipaldi, Gil de Ferran and Tony Kanaan, and series champion Cristiano da Matta.

He won the French F4 Championship before moving to Formula Renault Eurocup (2019-20), Toyota Racing Series (2020) and FIA Formula 3 (2021-23). These accomplishments helped Collet become the reserve and simulator driver for the Nissan Formula E Team in 2024.

"Caio is a welcome addition to AJ Foyt Racing,” team president Larry Foyt said. “He has shown great potential in INDY NXT by Firestone and in the junior formulas in Europe. I was impressed with how he adapted to our car at the recent Mid-Ohio test, and I'm very excited to see what he can do in INDYCAR. There's no doubt that he will be a strong contender in the battle for Rookie of the Year."

Combitrans Amazonia is a Brazilian logistics corporation that provides road cargo transportation, excluding hazardous materials, and moving services conducted on an intercity, interstate and international basis.

"Caio Collet’s dream is our dream," said Marcelo Camargo, owner and president of Combitrans Amazonia. "Brazil deserves the excitement of a full-time INDYCAR driver. We are thrilled to be part of this project with AJ Foyt Racing and carrying the Brazilian flag among so many global brands in the NTT INDYCAR SERIES.”

The 2026 NTT INDYCAR SERIES season starts Sunday, March 1 with the Firestone Grand Prix of St. Petersburg in St. Petersburg, Florida.
