The highly-anticipated debut of IndyCar’s new hybrid powertrains will have to wait another year. Originally planned to come onboard in 2023, the new engine features a 2.4-liter, twin-turbocharged V-6 using hybrid technology. Due to ongoing global supply chain challenges with some hybrid system components, the series has announced that it has postponed the move.
After consulting with engine partners Honda and Chevrolet, the series will continue to use the current 2.2-liter, twin-turbocharged V-6 power plant for the 2023 season. This comes on the heels of more than a year of delays with the energy recovery systems (ERS) and other vital components.
“We are pleased with the pace of the technical development of the 2.4-liter, twin-turbocharged V-6 hybrid as we prepare it for competition,” said IndyCar President Jay Frye. “We are very encouraged by the progress our team and our partners have made, but an immediate decision needed to be made to ensure we are prepared for the 2023 season utilizing our current 2.2-liter engine package.

Chevrolet remains fully committed to the NTT IndyCar Series, and we look forward to debuting our future engine package in 2024.”
Both Honda and Chevrolet will test the 2.4-liter engines at the end of the month (March 30-31) at Sebring International Raceway. New ERS units will also be tested, with lighter transmissions and bellhousings that have been developed. More testing and development work to incorporate the hybrid component will continue throughout the year.
