A dramatic four-car crash occurred on the final lap of Sunday's IndyCar Series race at Iowa Speedway, severely impacting drivers Sting Ray Robb, Alexander Rossi, Kyle Kirkwood, and Ed Carpenter. The crash was triggered when Rossi's car, running low on fuel, slowed down, causing Robb to collide with him, launch into the air, and flip over twice before skidding down the track. Kirkwood and Carpenter were also involved, with Carpenter's car landing atop Kirkwood's. Robb was transported to a hospital but was later released and reported to be in good condition. The race was ultimately won by Will Power, who overtook Alex Palou to secure his 43rd series victory. This incident highlights the critical safety role of the aeroscreen, which likely prevented more serious injuries.
