Technical Glitch Delays Start of first Hybrid-Era Indy 500 Open Test

The 2025 Indianapolis 500 Open Test encountered an unexpected delay on its first day due to technical issues at the Indianapolis Motor Speedway. A communication failure between race control and the teams prevented the scheduled veteran testing session from commencing on time, as drivers were unable to receive critical radio instructions.
„Sounds like a radio/communications issue between race control & teams and drivers. Once they get rolling, veterans will get the full 2 hours, and then the ROP will be a full 2-hour session, so today’s schedule will get pushed back a bit.“ (Nathan Brown on X)
Despite this early setback, INDYCAR officials managed to address the problem, allowing the day’s testing to proceed, albeit on a revised schedule. The delay compressed the planned sessions, but teams and drivers adapted to make the most of the available track time.
This year’s test is particularly significant as it marks the first time the Indianapolis 500 will feature hybrid power units. The integration of hybrid technology introduces new variables for teams, especially concerning energy regeneration and deployment strategies during both qualifying and race conditions. Scott McLaughlin’s race engineer, Ben Bretzman, highlighted the added complexity, noting that understanding the efficiency of the hybrid system is crucial, especially given the unique demands of the Indianapolis Motor Speedway.
As teams continue to gather data and refine their setups, the focus remains on adapting to the hybrid systems and optimizing performance for the upcoming race. The Open Test serves as a critical opportunity for teams to evaluate their strategies and ensure readiness for „The Greatest Spectacle in Racing.“
