The 2010 24 Hours of Le Mans (24 Heures du Mans 2010) will be the 78th Grand Prix of Endurance, taking place on June 12–13, 2010 at the Circuit de la Sarthe, Le Mans, France, and organised by the Automobile Club de l’Ouest (ACO).
Automatic entries to the 2010 24 Hours of Le Mans will be granted to teams that have performed well in the previous year’s 24 Hours of Le Mans, as well as the 2009 seasons of the American Le Mans Series, Le Mans Series, Asian Le Mans Series, FIA GT Championship, and the Petit Le Mans. An automatic invitation is also awarded to the team which accumulates the most points in the Michelin Green X Challenge as part of the Le Mans Series. The award is based on fuel economy of competitors during each event. On 19 November 2009 the ACO published their automatic invitations to 29 teams.
