Alexander Rossi completes Sebring IR28 test of IndyCar's new car; what was the goal for this round?

Another round of testing for IndyCar's 2028 chassis, the Dallara IR28 , is in the books after Alexander Rossi piloted the car Tuesday at Sebring International Raceway in Sebring, Florida. After a fuel system issue held Alex Palou to just 43 laps in the cockpit during his testing session Monday, Rossi completed 134 laps. When Rossi and Palou drove the IR28 on the Indianapolis Motor Speedway road course and oval this summer, the goal was to ensure everything worked properly. At Sebring, IndyCar and Dallara instructed the drivers to drive as they normally would at a test.
