IMSA GTP learnings helping Chevrolet, Honda with IndyCar’s hybrid unit
Cadillac and Acura represented the two manufacturers in the IMSA SportsCar Championship in 2023, completing their first season in the hybrid-infused GTP class. Each manufacturer was allowed to create their own powerplant within certain rules and limitations on system output and engine speed. Cadillac developed a 5.5-liter naturally aspirated V-8, while Acura opted for a twin-turbo V-6 engine. In IndyCar, both Chevrolet and Honda collaborated on a single hybrid system that fits their respective 2.2-liter engines. Testing and development for the hybrid systems have been extensive, with thousands of miles logged at various tracks. The experience gained from IMSA and other areas has contributed to the development of the hybrid system for IndyCar.
