The FIA World Endurance Championship (WEC) is an endurance auto racing series administered by the governing body of motorsport, the Fédération Internationale de l'Automobile (FIA), and co-organised and promoted by the automotive group, the Automobile Club de l'Ouest (ACO). There were two types of car called Le Mans Prototype (LMP) and Le Mans Grand Touring Endurance (LMGTE) divided into four classes when the WEC began in 2012: Le Mans Prototype 1 (LMP1), Le Mans Prototype 2 (LMP2), Le Mans Grand Touring Endurance Pro (LMGTE Pro) and Le Mans Grand Touring Endurance Am (LMGTE Am). The Le Mans Hypercar (Hypercar) class was introduced in the 2021 season to replace the LMP1 category and the Le Mans Daytona Hybrid (LMDh) class was introduced in the 2022 championship.
