IndyCar’s next-generation engine will test for the first time on-track next week as Honda and Chevrolet will get proper running on parts of the ex-Formula 1 layout at the Indianapolis Road Course.
IndyCar is switching to a hybrid-supported 2.4-litre engine – up from the 2.2-litre unit in use since 2012 – but has had to delay the introduction of the new power plant until 2024 for what the series called “ongoing global supply chain challenges”.
That means the cars will run naturally aspirated for this test – without the hybrid unit – on Monday and Tuesday, March 28-29.
The test had originally been planned for Sebring on March 30-31 but has been moved.
Chevrolet and Honda have both racked up significant mileage on dynos without the hybrid unit so the lack of a hybrid isn’t expected to cause serious issues.
It is not yet clear which teams and drivers will be involved in the test, but it is a private event and The Race understands that IndyCar is using sections of the F1 layout is in a bid to avoid any team or driver getting representative running if the road course they will race on twice this year in the IndyCar Series.
Two days after the test, around 20 IndyCar drivers are expected to test on the IMS road course ahead of May’s race there.
