IndyCar’s new IR-28 chassis is put through durability testing at Sebring International Raceway by Alex Palou, who drives the Honda-powered car for Chip Ganassi Racing. After earlier smoothness evaluations on the oval and road course at Indianapolis Motor Speedway, the Sebring session represents the first full durability check on the circuit’s challenging bumps and surface.
Multiple outlets report that Palou’s on-track time is shortened when a fuel issue interrupts the day’s testing. Yahoo Sports adds that Palou does briefly share track time alongside IndyCar driver Kyle Kirkwood during the session. Forbes and Motorsport.com focus more on the purpose and setting of the test—preparing the IR-28, which is scheduled to begin competition in 2028—while the interruption details highlight how quickly the program adjusts when issues arise.
