To meet the new regulations brought in by the ACO for endurance racing, the 03 has been cost-capped along with all 2011 LMP2 cars with a price of €345,000.
The Oreca 03 uses the same body and aero package developed by Oreca's chief-engineer David Floury for the LMP1 car campaigned during the 2009 and 2010 season by the works team.
