LMDh

A Le Mans Daytona h (LMDh for short) is a racing car built to compete in the premier class of the IMSA WeatherTech SportsCar Championship and the World Endurance Championship (WEC). The LMDh regulations were created jointly by the International Motor Sports Association (IMSA), the Automobile Club de l'Ouest (ACO) and the Federation Internationale de l'Automobile (FIA), to allow cars to compete alongside those in class Le Mans Hypercar (LMH) in the world endurance championship. Cars built to the LMDh regulation have replaced IMSA's Daytona Prototype International Class (DPI) from 2023. LMDh builders must incorporate a specific hybrid system producing 50kW (67hp) in their propulsion package, with a maximum power between 480 and 520kW. This system forms a key part of the so-called backbone of the car: all LMDhs are based on LMP2 chassis. The category has been designed in such a way as to make participation in the WEC and IMSA championships easier and more direct. In fact, many brands that race in the world championship also have at least one car in the American championship.
