We are most proud of the many advancements that the NTT IndyCar Series has. “The 2.2-liter IndyCar engines supplied by Honda and Chevrolet have provided the most competitive racing in the world. The 2024 hybrid engine package will provide even more excitement with horsepower increases over the current engine.” Said IndyCar President Jay Frye.
The series has decided to stick with the tried-and-true 2.2-liter engine specifications that have been in use since 2012.

Both Chevrolet and Honda had been working over the past year to get the new engines ready for usage, and reports suggested that the limited on-track testing had gone off without a hitch.
It was decided to at least temporarily put the new motor’s development on hold due to ongoing supply chain concerns and the simultaneous introduction of a hybrid electronics system to the power supply.
The idea is now to attach the electric power components to the current combustion engine while the hybrid components are still actively being developed. Source
