Modifications were made to the circuit in the run-up to the race. A new entry run-off area was constructed at the Porsche Curves in response to a major accident sustained by Duval during practice for the 2014 24 Hours of Le Mans although the turn's alignment was not altered. SAFER barriers were installed on the outside of the first entry section of the turn, marking the technology's first appearance at a European motor racing venue. Vincent Beaumesnil, the Automobile Club de l'Ouest's (ACO) sporting manager, revealed was easier to install a chicane, but following discussions with the national motor racing governing body of France, the Fédération Française du Sport Automobile, the circuit's layout was allowed to remain unchanged.
