INDYCAR is planning to debut a new chassis and engine formula in 2028, the Indianapolis-based sanctioning body announced.

Dallara, the Italian car designer and builder with facilities in Speedway, Indiana, will produce the chassis, which will feature a look designed to appeal to a new generation of fans while keeping styling cues recognized by all as an INDYCAR SERIES car, according to series officials. Dallara has produced chassis for the series since 1997 and has been the series' exclusive chassis supplier since 2008.

Evolution of the new chassis has included work by Dallara and recently developed simulation technology, aimed at enhancing overall "raceability."

Working in tandem with Dallara and other component suppliers, the overall car design includes a projected weight reduction of 85-100 lbs. compared to the current INDYCAR SERIES chassis.

Plans also include a new engine formula, utilizing 2.4-L twin-turbocharged V6 internal combustion engine, which is expected to provide more torque and power over the current engine formula.

Xtrac, an exclusive supplier for INDYCAR since 2000, will continue to provide transmissions for the new chassis. Development for 2028 includes a gearbox that will shed 25 pounds from the currently used unit and one that will share components with a future INDY NXT by Firestone gearbox – streamlining components for teams also involved in INDYCAR's development series.

Low-voltage hybrid engine technology, introduced to series competition with a successful launch in July 2024, will continue to evolve in the new car with longer deployment, more horsepower gain and overall improved performance.

Performance Friction Corporation (PFC) once again will be the exclusive supplier of brake system components for the series, as it has since 2017.

Safety also will continue to be a focus of Dallara's design, in close collaboration with INDYCAR technical and medical response officials, the series said. The new car will bolster safety to new benchmarks with an ergonomic driver cockpit to improve seating position, an integrated aeroscreen and a new roll hoop. The existing chassis was retrofitted with the aeroscreen upon that safety device's introduction in 2020.

Renderings and more information about the new car, along with additional partners, will be announced at a later date.
