A group of cars at the Road America, featuring three LMDh manufacturers
An LMDh (Le Mans Daytona h)[1] is a type of sports prototype race car that competes alongside Le Mans Hypercar entries in the Grand Touring Prototype (GTP) class of the IMSA SportsCar Championship from 2023.[2] It also competes in the Hypercar class of the FIA World Endurance Championship.[3]
The LMDh ruleset was created jointly by the International Motor Sports Association (IMSA) and the Automobile Club de l'Ouest (ACO).[4] The cars serve as the successor to the Daytona Prototype International class, utilising regulations that were planned to become the next-generation Daytona Prototype International ruleset, converged with the Le Mans Hypercar ruleset.[5]
The FIA World Motor Sport Council had allowed LMDh cars to participate in the 2022 WEC season on a race-by-race basis, "to ensure the seamless introduction" in 2023, however no LMDh cars would actually participate at any race in the 2022 season, and they would actually first begin racing in the 2023 season.[6]
