The NTT INDYCAR SERIES announced on Tuesday that following successful testing by both Honda and Chevrolet, the new INDYCAR Hybrid Era will begin July 5-7 with the Honda Indy 200 at the Mid-Ohio Sportscar course.

Speaking about the news, the President of INDYCAR, Jay Frye, said:

“The strength of this uncharted partnership between Chevrolet and Honda has pushed this innovative project to the grid in 2024. “The INDYCAR-specific hybrid power unit will bring a new and exciting element to the NTT INDYCAR SERIES with additional energy and overtake options. We cannot wait to see the start of this new era at Mid-Ohio.”

INDYCAR’s hybrid power expands the series’ efforts to deliver the most competitive motorsport on the planet. The new powerplant unit will feature additional overtake (Push to Pass) options, ultimately giving INDYCAR SERIES drivers more choices and control – enhancing the on-track competition and excitement.

The innovative hybrid system consists of the low-voltage (48V) Motor Generator Unit (MGU) and Energy Storage System (ESS)—consisting of 20 ultracapacitors—both of which fit inside the bell housing, located between the Chevrolet and Honda INDYCAR SERIES internal combustion engine and the gearbox. During regeneration, acting on the clutch shaft, the MGU builds power to be stored in the ESS. The additional horsepower is deployed through the same motor generator on driver demand.

For the competition, options for automatic “regen” via braking or throttle position and manual “regen” via selected steering wheel paddles and buttons will be available. Deployment of stored energy will only be available manually through a latching button, similar to the existing Push to Pass system.

Eric Warren, General Motors Executive Director, Motorsports Competition commented saying:

The introduction of hybrid technology provides an opportunity to integrate electrification technologies into the NTT INDYCAR SERIES.

During the development of any new technology, extensive analysis and testing are done to identify as many issues as possible. We support INDYCAR’s decisions throughout this process to study testing data carefully and make sure that when the hybrid technology is integrated, the operation and performance are exactly what is expected.

“This approach has given INDYCAR and the engine manufacturers the opportunity to ensure the high level of competition continues uninterrupted.”

Honda Racing Corporation USA President David Salters said

“Hybrid technology is playing an ever-increasing role in both our racing programs and the production vehicles created by Honda and Acura,. “More than a quarter of Honda’s total sales in 2023 – nearly 300,000 vehicles – were Honda CR-V and Accord hybrids. Introducing electrification to INDYCAR at Mid-Ohio further aligns our racing efforts with Honda’s passenger car production as we operate multiple manufacturing and R&D facilities in central Ohio, employing more than 13,000 associates there.

“This is exciting new technology and, like all things new, has presented challenges to us at HRC as we have stepped in with our competitors to help INDYCAR make the hybrid system compact enough, powerful enough, light enough and reliable enough to work within the highly-restricted confines of an INDYCAR chassis. We are proud of our associates’ work to develop the supercapacitor pack and control software for the system. We look forward to hybrid tech adding another dimension to the great racing spectacle and entertaining our great Honda and INDYCAR racing fans.”

A full-field test of INDYCAR’s power unit is scheduled for Tuesday, June 11 at the Milwaukee Mile to allow teams to finalize implementation ahead of the July debut. On-track testing has taken place at Barber Motorsports Park, Homestead-Miami Speedway road course, Indianapolis Motor Speedway, IMS road course, Milwaukee Mile, Road America, Sebring and World Wide Technology Raceway to effectively mirror the disciplines of the NTT INDYCAR SERIES schedule.
