Convinced by the new LMDh regulation, Cadillac prepared a car to race in the IMSA and FIA-GT championships starting from 2023. The car, signed V-LMDh, mounts the 5.5-litre LMC55R V8 engine with a power of around 680 HP. The 50kW ERS acts on the rear axle. The gearbox is 7-speed sequential, while the chassis is the work of Dallara, one of the manufacturers who have received the chassis builder license for the LMDh category.
