IndyCar has changed plans for its new engine formula again, but says it remains committed to introducing hybrid power units in 2024.Three years ago the series announced it would switch from its current 2.2-litre V6 twin-turbo engines to 2.4L versions mated to hybrid drive systems for the 2022 season. But the introduction of the new engines, intended to increase power from 700bhp to 900bhp, has been pushed back twice, first to 2023 and then 2024.
Today the series announced it has “paused” plans to introduce its larger, 2.4L engines. However it remains determined to add hybrid drive to the series in the season after next. These will now be incorporated alongside the 2.2L motors which the series has used since 2012.
“The 2.2L IndyCar engines supplied by Honda and Chevrolet have provided the most competitive racing in the world,” said IndyCar series president Jay Frye. “The 2024 hybrid engine package will provide even more excitement with horsepower increases over the current engine.”
An IndyCar spokesperson denied the decision to continue using the 2.2L engines was a result of parts shortages or supply chain problems. The series remains committed to the current timeline for the introduction of its new power units, testing of which will continue in 2023.
The introduction of hybrid power units is part of IndyCar’s move to improving the sustainability of its championship. Its cars will use “100% renewable” fuel from the start of next season and it will expand the use of sustainable guayule rubber which appeared in some of the tyres raced during 2022.
