Chevrolet and Honda have swiveled their resources from testing their 2.4-liter engines to cooperating with each other and working with a new hybrid component supplier after it became clear that the proposed component from Mahle would be insufficient for the rigors of IndyCar racing and would not be ready in time for the 2024 season.
On the eve of the 2022 season, IndyCar announced that adoption of the new formula was being pushed back from ’23 to ’24, due to global parts supply chain issues. Mahle, which was building and developing the hybrid component, was struggling like several companies as chips or semi conductors were in short supply.
