The 2006 1000 km of Istanbul was the opening race of the 2006 Le Mans Series season run by the ACO. It was run on April 9, 2006.
Due to a mistake made by event organizers, not enough fuel was brought to Istanbul to be able to supply all the entrants for a distance of 1000 km. Thus, the race was quickly shortened to a 4-hour timed race in order to ensure that there would be enough fuel for everyone.[1][2]
