The FIA World Endurance Championship, abbreviated as WEC, is an auto racing world championship organized by the Automobile Club de l’Ouest (ACO) and sanctioned by the Fédération Internationale de l’Automobile (FIA). The series supersedes the ACO’s former Intercontinental Le Mans Cup which began in 2010 and is the first endurance series of world championship status since the demise of the World Sportscar Championship at the end of 1992. The World Endurance Championship name was previously used by the FIA from 1981 to 1985.
