Freedom 250 is hybrid-powered. How IndyCar signals industry direction.

This weekend’s NTT IndyCar Freedom 250 in Washington, D.C., arrives as the series unveils its next-generation hybrid chassis. IndyCar’s mild-hybrid approach over the past two years has reinforced Penske Entertainment’s decision to move cautiously on electrification compared with European open-wheel rivals pushing toward full electric. The new IR-28, built by Italian supplier Dallara, evolves from the current DW-12, with more than 800 horsepower and an estimated 85-15 gas-electric split. Early driver testing has drawn strong praise, with the chassis set to enter service at the end of the 2027 season.
