Five-time IndyCar Series champion and 2025 Indianapolis 500 winner Alex Palou completed the second day of IndyCar’s IR-28 oval validation test Thursday at Indianapolis Motor Speedway, wrapping up running 15 minutes early after finishing his team's full checklist.
Palou, representing Honda teams for Chip Ganassi Racing, took over testing duties following Wednesday's initial oval runs by ECR’s Alexander Rossi, who represented Chevrolet. While Rossi logged laps in sweltering 90-degree heat and high humidity, an approaching cold front dropped temperatures nearly 10 degrees Thursday, providing IndyCar and chassis manufacturer Dallara with a broader spectrum of environmental data.
