While the current Dallara DW12 chassis has survived 14 years of service with continual safety and performance updates, it should have been replaced years ago. IndyCar unveiled the Dallara IR-28, which is slated to make its competitive debut in 2028. At first glance, the IR-28 features a hallmark of a modern single-seater race car: curved transitions between main planes and end plates. The aeroscreen that IndyCar introduced in 2020 to improve cockpit safety is now a fully integrated part of the chassis rather than a bolt-on addition. The series claims that IR-28 will be 100 pounds lighter than the current car.
