IndyCar Set to Debut Ultracapacitor Hybrid Engine System After Years of Development

INDIANAPOLIS — At an upscale steakhouse in downtown Indianapolis, engineers from Chevrolet and Honda raised a toast just days before their engines would compete in the Indianapolis 500. Despite being rivals on the track, they collaborated to push the IndyCar Series into a new era.

Together, they developed a hybrid unit that can fit inside the existing Dallara chassis and work with each manufacturer’s twin-turbocharged V-6 engines. This innovative design is set to revolutionize IndyCar racing.

Team Penske driver Scott McLaughlin described the upcoming change as a “massive shift” that will impact all teams. The hybrid system will make its debut at Mid-Ohio during an IndyCar regular-season race presented by the 2025 Honda Civic Hybrid.

Arrow McLaren team principal Gavin Ward expressed optimism about the transition to hybrid technology, viewing it as an opportunity for growth and advancement in the series.

Innovation in Action

The journey towards hybridization began when Chevrolet and Honda recognized the shift in consumer demand towards hybrid and electric vehicles. To align with this trend, they set out to integrate hybrid technology into IndyCar racing.

The collaborative effort between Chevrolet and Honda focused on developing specific components for the hybrid system. Chevrolet worked on the motor generator unit (MGU), while Honda focused on the energy storage system (ESS). The resulting system fits seamlessly into the space between the engine and gearbox.

Extensive testing of the hybrid system has been conducted at various tracks, including oval tracks and road courses, to ensure its performance and reliability. The partnership between the two manufacturers has been crucial in the successful development of this groundbreaking technology.

Despite delays, IndyCar remains committed to introducing the hybrid system midway through the current season. This decision demonstrates the series’ dedication to innovation and progress.

“We just want to make it introduced at the right time,” Ward said, highlighting the aggressive timeline for implementation.

Driving Towards the Future

The hybrid system in IndyCar marks a significant step towards embracing evolving technology and sustainability. By utilizing ultracapacitors instead of traditional batteries, IndyCar’s hybrid system offers a lightweight and powerful solution for energy storage.

The boost provided by the hybrid system enhances engine performance, pushing IndyCar engines over 800 horsepower for the first time in decades. This boost can be strategically deployed by drivers, adding a new level of complexity to race strategies.

Most major IndyCar teams have experience with hybrid technology through other racing programs, which has prepared them for the upcoming changes. Drivers acknowledge the learning curve ahead but are excited about the new dynamic the hybrid system will bring to the series.

As the series embraces hybrid technology, it also marks the end of an era in IndyCar. Drivers and teams are optimistic about the future and the opportunities for growth and innovation in the sport.
