IndyCar is considering whether to commission a new chassis from Dallara or continue updating the existing DW12 and IR18 models. The decision depends on future engine and energy recovery system (ERS) developments, with a potential shift to a high-voltage ERS possibly necessitating a new chassis design by 2027.
IndyCar has completed its investigation into the cause of Kyle Kirkwood's Indy 500 crash, where the left-rear wheel assembly on his Andretti Autosport car broke free and sailed over the Turn 2 grandstands. The analysis revealed that the failure was due to a freakish failure of the retaining nut that holds the wheel hub and wheel bearings into the upright. In response, Dallara has designed a new, wider nut made from a different grade of steel to decrease the likelihood of it being stripped off the hub's threads. The new nut will be implemented starting this weekend at the Hy-Vee doubleheader at Iowa Speedway.
IndyCar and Roger Penske are investigating the cause of Kyle Kirkwood's left rear wheel detaching from his car during the Indianapolis 500 and flying over the Turn 2 grandstands. Penske spoke with Dallara's founder and owner to address the mechanical failure, and IndyCar confirmed that the rear tethers remained intact. Kirkwood believes the car's left-rear upright assembly "shredded" upon impact with another car, but IndyCar stated that the tire tether did not fail. No injuries were reported, but one spectator was hit by debris and suffered minor injuries. IMS will purchase a new car for the owner of the car hit by the flying wheel.
