Post-Race
Following a successful turn out from a large number of European teams, as well as a handful of American and Japanese teams, the event was considered a success. With this, the ACO pushed forward with their development of the Le Mans Endurance Series, debuting in 2004. This move would also lead to the demise of the FIA Sportscar Championship, as prototype teams chose instead to participate in LMES.
Since this event, the LMES has not returned to Le Mans as part of their regular schedule, although many LMES participants race in the 24 Hours of Le Mans.
