2013 24 Hours of Le Mans

The 81st 24 Hours of Le Mans (French: 81^e 24 Heures du Mans) was a 24-hour automobile endurance racing event for teams of three drivers entering Le Mans Prototype and Le Mans Grand Touring Endurance cars held from 19 to 23 June 2013 at the Circuit de la Sarthe close to Le Mans, France. It was the 81st running of the event, as organised by the Automobile Club de l'Ouest (ACO) since 1923. The race was the third and the premier round of the 2013 FIA World Endurance Championship, with 32 of the race's 56 entries contesting the championship. A test day was held two weeks prior to the race on 9 June. Approximately 245,000 spectators attended the event.

The race was won by an Audi R18 e-tron quattro shared by Dane Tom Kristensen, Brit Allan McNish and Frenchman Loïc Duval after it led the last 248 laps, taking the manufacturers' twelfth victory at Le Mans since its first in the 2000 edition. It was Kristensen's ninth victory, McNish's third and Duval's first. The car started from pole position but lost the lead at the start to the sister No. 1 Audi of André Lotterer, Marcel Fässler and Benoît Tréluyer who traded the position with a Toyota TS030 Hybrid shared by Anthony Davidson, Stéphane Sarrazin and Sébastien Buemi under pit stop rotation until it was forced into the pit lane in the seventh hour with a crankshaft position sensor fault. Buemi, Davidson and Sarrazin finished second and Lucas di Grassi, Marc Gené and Oliver Jarvis in another Audi completed the race podium.

The Le Mans Prototype 2 (LMP2) category finished with the OAK Racing Morgan car of Bertrand Baguette, Martin Plowman and Ricardo González ahead of the sister entry of Alex Brundle, David Heinemeier Hansson and Olivier Pla by a distance of one lap. The class podium was completed by Greaves Motorsport's Zytek Z11SN, driven by Michael Krumm, Jann Mardenborough and Lucas Ordóñez. One of Porsche's Manthey Racing 991 RSR of Romain Dumas, Marc Lieb and Richard Lietz won the Le Mans Grand Touring Professional (LMGTE Pro) class and the sister No. 91 vehicle of Jörg Bergmeister, Timo Bernhard and Patrick Pilet in second. Porsche also won the Le Mans Grand Touring Amateur (LMGTE Am) category with the No. 76 IMSA Performance Matmut car of Raymond Narac, Christophe Bourret and Jean-Karl Vernay, earning the marque its 100th class victory at Le Mans.

The result elevated Kristensen, McNish and Duval to the top of the Drivers' Championship with 94 points.
