IndyCar 2028: The hybrid system
RACER - Racing News••technology
Key Points:
- IndyCar is developing a second-generation hybrid energy recovery system (ERS) for its 2028 IR28 chassis, aiming to significantly increase energy storage capacity and power output compared to the current Version 1 system.
- The Version 2 hybrid system will be housed in the same compact bellhousing area behind the engine as the current system, with a focus on doubling ERS power to 120hp and extending power deployment duration from 5 to around 10 seconds.
- The current motor generator unit (MGU), developed by Empel, has the capability to deliver up to 150hp, but its output has been limited by the smaller energy storage system; the new ESS will enable fuller use of the MGU's potential.
