2015 24 Hours of Le Mans

The 83rd 24 Hours of Le Mans (French: 83^e 24 Heures du Mans) was a 24-hour automobile endurance event for teams of three drivers each entering Le Mans Prototype and Le Mans Grand Touring Endurance cars held from 10 to 14 June 2015 at the Circuit de la Sarthe, close to Le Mans, France. It was the 83rd running of the 24 Hour race organised by the Automobile Club de l'Ouest as well as the third round of the 2015 FIA World Endurance Championship. A test day was held two weeks prior to the race on 31 May. A record-breaking 263,500 people attended the event.

A Porsche 919 Hybrid driven by Neel Jani, Romain Dumas, and Marc Lieb started from pole position after Jani broke the circuit's lap record in qualifying. The race was won by the sister Porsche of Nick Tandy and Le Mans rookies Earl Bamber and Nico Hülkenberg, followed a lap behind by a third Porsche shared by Mark Webber, Brendon Hartley and Timo Bernhard. Audi's best car, driven by the title defenders Benoît Tréluyer, Marcel Fässler, and André Lotterer, finished third, a further lap behind the two Porsche vehicles. This was the seventeenth overall victory for Porsche, their first since 1998 and also the first gasoline-powered car to win the 24 Hours of Le Mans overall since 2005.

The LMP2 category was won by the KCMG Oreca-Nissan driven by Richard Bradley, Matthew Howson, and Nicolas Lapierre. The trio led all but nine laps of the race but only held a 48-second lead over the Jota Sport Gibson-Nissan at the race's end. Corvette Racing won their first class victory since 2011 despite one of their two cars being withdrawn after an accident in qualifying. Oliver Gavin, Tommy Milner, and Jordan Taylor held a five-lap margin in LMGTE Pro over the AF Corse Ferrari in second, after breaking away from the rest of the field in the second half of the race. The LMGTE Am class was led for most of the time by the No. 98 Aston Martin until driver Paul Dalla Lana crashed in the Ford Chicane in the final hour of the race, handing the victory to the SMP Racing Ferrari of Viktor Shaytar, Aleksey Basov, and Andrea Bertolini.

The result meant Lotterer, Tréluyer and Fässler remained the leaders of the Drivers' Championship on 80 points, 20 ahead of Tandy, and a further two in front of his co-drivers Bamber and Hülkenberg. Dumas, Jani and Lieb dropped from second to fourth and Bernhard, Hartley and Webber stood in fifth place. Porsche became the new leaders of the Manufacturers' Championship with 140 points; Audi were 16 points behind their nearest rivals with Toyota 69 points adrift in third with five races left in the season.
