The NTT IndyCar Series has announced the postponement of its 2.4-liter, twin-turbocharged V-6 engine with hybrid technology to 2024.
The power unit was originally planned to make its debut in next year in North America’s premier open-wheel championship. However, the impact of a global supply chain shortage with some of the various hybrid components have led to the decision for the delay. After discussions with engine suppliers Chevrolet and Honda, the series will extend the use of the current 2.2-liter, twin-turbocharged V-6 powerplant for the 2023 season.
“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 Jay Frye, President of IndyCar. “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.
“Thanks to our great partners at Honda and Chevrolet for working through this challenging supply chain situation. We are going full speed ahead with the 2.4-liter hybrid engine and cannot wait to have it on track in 2024.”
The 2024 power unit will feature a baseline of 800 horsepower, and a hybrid system to provide an additional boost of 100 horsepower.
“We are proud of the hard work and level of commitment by our engine group, along with our teams and partners, in the development of the Chevrolet 2.4-liter engine for our IndyCar program,” said Mark Stielow, director, GM Motorsports Competition Engineering. “We were certainly excited to have it on track next season. Chevrolet remains fully committed to the NTT IndyCar Series, and we look forward to debuting our future engine package in 2024.”
David Salters, the President and Technical Director of Honda Performance Development, added, “We are very excited to get the electrified era of IndyCar Series racing underway. We have finished development and dyno testing of our new internal combustion engine, and once the hybrid system component supply chain issues are sorted, we’ll begin track testing of the new hybrid power unit.”
The site of the first on-track test of IndyCar’s 2024 engine is set for March 30-31 at Sebring International Raceway.
The next stop for the 2022 season is the XPEL 375 at Texas Motor Speedway, with coverage beginning at 12:30 p.m. (ET) on NBC and simulstreamed on Peacock Premium. Coverage is also available from the INDYCAR Radio Network with audio available via the IndyCar App powered by NTT DATA.
