IndyCar provided an update on the next-gen chassis before qualifying in Wisconsin, revealing plans for a lighter car with a more powerful engine. This change comes after a private meeting with team owners where details were discussed. Scheduled for a 2028 launch, the new chassis will undergo on-track testing starting in early 2026. Key changes include weight reduction, a 2.4-liter twin-turbocharged V-6 engine, and advancements in the hybrid unit technology. Dallara will manufacture the chassis, Xtrac the transmissions, and PFC will supply brakes, while engine suppliers remain undisclosed. The new design aims to enhance competition, powertrain development, and safety standards, addressing areas like hybrid system performance, driver cockpit ergonomics, and exterior features. The current IndyCar chassis, in use since 2012, has been continually adapted to incorporate modern enhancements such as the aeroscreen and hybrid unit.
