An LMDh (Le Mans Daytona h) is a type of sports prototype race car that will compete alongside Le Mans Hypercar entries in the Grand Touring Prototype (GTP) class of the IMSA SportsCar Championship from 2023. It also competes in the Hypercar class of the FIA World Endurance Championship. The LMDh ruleset was created jointly by the International Motor Sports Association (IMSA) and the Automobile Club de l'Ouest (ACO). The cars will 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. The FIA World Motor Sport Council allowed LMDh cars to participate in the 2022 WEC season on a race-by-race basis, "to ensure the seamless introduction" in 2023. History DPi 2.0 Following the FIA World Endurance Championship's transition to a winter calendar in 2018, IMSA announced in January 2018, that it would extend the homologation periods for LMP2, DPi and GTE-spec machinery in the WeatherTech SportsCar Championship by an additional year. This would delay the homologation periods in the championship by roughly six months, which necessitated the homologation extension from IMSA. As such, the DPi and LMP2 cars, which were originally confirmed for a four-year period through 2020, would now be eligible for competition until at least the end of the 2021 season. Despite calls from manufacturers to retain the DPi platform and regulations for the 2022 season, then-IMSA President Scott Atherton announced that IMSA was looking at other options beyond a further extension to the life of the DPi platform. On May 6 2019, IMSA announced that the next generation DPi ruleset, known as DPi 2.0 would be an evolution based on the current LMP2-based platform, featuring Hybrid technology from a single supplier, with supply voltage being unconfirmed. A few days later, IMSA's VP of Competition Simon Hodgson stated that the next-generation DPi regulations would be expected to feature increased styling measures, by opening up more areas where manufacturers were able to add styling cues. Hodgson also indicated that the enlarged scope for styling cues may also come alongside regulations that dictated minimum level of styling required from each manufacturer. On June 24 2019, it was revealed that IMSA had held discussions with manufacturers regarding the incorporation of hybrid technology in the next-generation DPi ruleset, with manufacturers on the DPi 2.0 steering committee divided over the level electrification
