Why Alex Palou's day testing IndyCar's new car at Sebring was cut short
Alex Palou tested the new IndyCar IR28 chassis at Sebring before a fuel issue cut his day short. Palou briefly drove alongside Kyle Kirkwood.
IndyCar and Dallara introduced their new chassis, the IR28, for testing outside Indianapolis Motor Speedway for the first time. Alex Palou, a five-time IndyCar champion, participated in his fourth day of testing the car on Monday at Sebring International Raceway in Sebring, Florida. The same drivers, Palou and Alexander Rossi, continued testing on Tuesday.
Sebring is known for being one of the bumpiest courses in North America due to its physicality and height of bumps, reasons why IndyCar only tests there instead of running full races. During the Monday testing session, the IR28 faced a fuel system issue, ending Palou's day early after 43 laps. The engineering team, comprising members from various IndyCar teams, was unable to revive the car.
Palou mentioned that he drove well, braking deeply compared to the DW12, and that the car's new cooling system was effective in the warm Florida humidity. The issue was resolved, and Rossi will test the IR28 again on Tuesday. IndyCar plans to carry out further testing this fall before each team tests their respective chassis with the new 2.4-liter twin-turbocharged V6 engine.
