The 2013 Le Mans 24 Hours will take place on 22-23 June. It is a very important running of the greatest endurance race in the world as it will celebrate its 90th anniversary! The test day will now be held on Sunday 9th June. The dates of the 2013 Le Mans 24 Hours, initially scheduled for 15-16 June, have been put back by a week at the request of the Fédération Internationale de l’Automobile (FIA) in order to harmonize the world calendar of motor racing events. Thus, the Automobile Club de l’Ouest, the FIA’s partner in the World Endurance Championship, has decided to put back the blue riband event on its own calendar by seven days. The test day will again take place two weeks before the race on Sunday 9th June 2013. Scrutineering (technical and administrative checks) will be on Sunday 16th and Monday 17th June. The Automobile Club de l’Ouest will celebrate in the style it deserves the 90th anniversary of the Le Mans 24 Hours on 22-23 June 2013.
