IndyCar Announces New Lighter Chassis For 2028 Season

IndyCar has announced a new chassis set to debut in the 2028 season, with on-track testing planned for early 2026. The new car, produced by Dallara, will feature a weight reduction of 85-100 pounds, including a lighter gearbox, and will be powered by a new 2.4-liter twin-turbo V6 engine paired with a low-voltage hybrid system that builds on the hybrid technology introduced in 2024. The design aims to attract a new generation of fans while maintaining classic IndyCar styling cues and improving safety, raceability, and competition across all four types of circuits: superspeedways, short ovals, street circuits, and permanent road courses. IndyCar President J. Douglas Boles emphasized that the new chassis is a necessary evolution following significant updates like the aeroscreen and hybrid power unit on the current DW12 chassis, which has been in use since 2012. Collaborative work between IndyCar engineers, Dallara, and component suppliers has focused on competition, powertrain development, and safety to ensure enhanced on-track performance and fan appeal. Engine manufacturers for the new formula will be announced at a later date.
