Dallara IR-28 Coming to iRacing? UPDATE:
#cars #indycar #rumor
  • IndyCar officially unveiled the Dallara IR-28 on July 28, 2026, the chassis and powertrain package replacing the IR-18 when the 2028 NTT INDYCAR SERIES season begins. The car is approximately 100 pounds lighter than the current IR-18, powered by a new 2.4L twin-turbo V6 hybrid producing up to 760hp. iRacing has held the official IndyCar license since the IR-18 era and matched the real-world car debut with a sim release in the same year. No official iRacing announcement on the IR-28 yet, but the precedent and the partnership make it a near-certain eventual addition. (IndyCar Official Announcement) (07.28.26)
