The series currently known as INDY NXT debuted in 2002 as a feeder series for the then-Indy Racing League, and it took on its current name in 2023 when it was acquired by Penske Entertainment. It has become highly effective at graduating drivers into the premier NTT INDYCAR Series, with future INDYCAR champion Josef Newgarden and fellow stars Patricio O’Ward and Kyle Kirkwood each using INDY NXT titles to springboard their future successes at the highest level.
INDY NXT’s weapon of choice is the Dallara IL-15. Introduced in 2015, it features 450 base horsepower (plus an additional 50 with push-to-pass) coming out of a turbocharged 2.0-liter inline-four. The car received updates in 2021 including a halo for driver safety and new engine tuning by AER to run a full season without a rebuild. The latest update to the car came in 2023, when Firestone took over as tire supplier after Penske’s acquisition of the championship.
