2025 NTT IndyCar Series (NaBB737)

The 2025 NTT INDYCAR Series will be the 114th official championship season of American open wheel racing and the 30th season under IndyCar Series sanction. The premier event will be the 2025 Indianapolis 500. It will be the sixth year under Penske management after they took over in late 2019.
==Contracted teams and drivers==
The following teams, entries and drivers have been announced to compete in the 2025 NTT IndyCar Series season. All teams use a spec Dallara IC-25 chassis with universal aero kits (one each for speedways, short ovals, and road courses) and Firestone tires. This is the first season of the new IC-24 chassis and the second season of the new 2.4L twin turbo hybrid engine formula. The latter change has brought Porsche back as an engine supplier to American open-wheel racing for the first time since 1990.
There are 28 full-season entries for the 2025 season. Honda supplies engines for 12 of these teams, Chevrolet provides the horsepower for 10, and 6 of them are powered by Porsche. (Part time entries are yet to be confirmed, so this table only lists full-season efforts)
