All 27 cars in IndyCar will have electrified power units, in addition to 2.2-liter internal combustion engines, resulting in over 800 horsepower to the rear wheels. The unique hybrid configuration aims to set IndyCar apart from other racing series that have integrated hybrid power. Development of the hybrid system was a lengthy process, with initial work done in collaboration with MAHLE to fit the system into the Dallara DW12 chassis. Despite delays due to technical and supply chain difficulties, Honda and Chevy have taken over the project and finalized the hybrid unit for introduction in 2024. Testing by series veterans like Scott Dixon and Will Power has helped evaluate the system’s performance and drive adjustments for optimal functioning on tracks. The hybrid system operates on similar principles as other automotive hybrids, using an electric motor on the driveshaft for power delivery and regeneration during braking.
