INDIANAPOLIS — The rumor was surfacing lately that INDYCAR’s best interest may be to delay the hybrid power at least another year. The testing programs that had taken place so far was showing some glaring issues that the Dallara chassis for which was introduced in 2012, wasn’t the right one for this new powerunit.
Plus, without a new manufacturer signed on for 2023 and supply issues, the writing was on the wall to push this back another year.
That’s exactly what happened on Thursday.
Due to ongoing global supply chain challenges with some hybrid system components, INDYCAR announced that it has adjusted the debut of the 2.4-liter, twin-turbocharged V-6 engine with hybrid technology to the 2024 season.
In consultation with engine partners Chevrolet and Honda, the NTT INDYCAR SERIES will continue to use 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 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.
“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 development of the 2.4-liter, twin-turbocharged V-6 engine with hybrid technology involves cutting-edge innovations unique to INDYCAR. The new engine will give the most exciting and competitive racing series in the world a roaring and powerful 800 horsepower as a baseline. The addition of the hybrid system will give an additional boost of 100 horsepower to ultimately produce 900.
“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.”
“We are very excited to get the electrified era of INDYCAR SERIES racing underway,” said David Salters, president and technical director, Honda Performance Development. “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 first on-track test of the new INDYCAR SERIES 2.4-liter, twin-turbocharged V-6 will come Wednesday, March 30 and Thursday, March 31 at Sebring International Raceway. Development, testing and work to incorporate the hybrid component will continue throughout the year.
This was initially supposed to be rolled out this season but COVID restrictions last year delayed that to 2023. Now, we get another delay and questions on if this is even right to do in general until we can roll out a new chassis and engine package at once.
