The80th 24 Hours of Le Mans (French:80^e 24 Heures du Mans) was a 24-hourautomobile endurance race for teams of three drivers each enteringLe Mans Prototype andLe Mans Grand Touring Endurance cars held from 16 to 17 June 2012 at theCircuit de la Sarthe close toLe Mans, France before 240,000 spectators. It was the 80th running of the event, as organised by the automotive group, theAutomobile Club de l'Ouest (ACO) since1923. The race was the third round of the2012 FIA World Endurance Championship, with 30 of the race's 56 entries contesting the championship. A test day was held two weeks prior to the race on 3 June.

AAudi R18 e-tron quattro driven byAndré Lotterer,Marcel Fässler andBenoît Tréluyer started frompole position after Lotterer set the fastest overall lap time in the third qualifying session. The team were untroubled in the opening hours of the race until aToyota TS030 Hybrid shared byAlexander Wurz,Kazuki Nakajima andNicolas Lapierre took the lead. Toyota relinquished it during asafety car period for a major accident at the start of the sixth hour. Audi's other team ofAllan McNish,Tom Kristensen andRinaldo Capello became their teammate's lead challengers until McNish crashed whilelapping slower traffic in the 22nd hour and providing Lotterer, Fässler and Tréluyer with a lead they maintained to the end of the race. It was Lotterer, Fässler and Tréluyer's second Le Mans win, Audi's eleventh and the first for ahybrid electric vehicle. The second Audi finished one lap behind in second place and a R18 ultra ofOliver Jarvis,Marco Bonanomi andMike Rockenfeller completed an Audi sweep of the podium positions in third.

TheLe Mans Prototype 2 (LMP2) class was won by theStarworks Motorsport team ofEnzo Potolicchio,Ryan Dalziel andTom Kimber-Smith in aHPD ARX-03b after they led the final 215 laps of the event. The trio finished ahead of Thiriet byTDS Racing'sOreca 03 car shared byPierre Thiriet,Mathias Beche andChristophe Tinseau and PeCom Racing'sLuís Pérez Companc,Pierre Kaffer andSoheil Ayari.Giancarlo Fisichella,Gianmaria Bruni andToni Vilander in anAF CorseFerrari 458 Italia GT2 held a three-lap lead inLe Mans Grand Touring Professional (LMGTE Pro) overLuxury Racing's trio ofFrédéric Makowiecki,Jaime Melo andDominik Farnbacher. The Le Mans Grand Touring Amateur (LMGTE Am) category was won byLarbre Compétition'sChevrolet Corvette C6.R ofPatrick Bornhauser,Pedro Lamy andJulien Canal after Lamy overtook Anthony Pons,Nicolas Armindo and Raymond Narac'sIMSA Performance MatmutPorsche 997 GT3-RSR in the final hour.

Due to the result of the race, McNish, Kristensen and Capello were elevated to the lead of theDrivers' Championship, 6½ points over the race winners Lotterer, Fässler and Tréluyer in second position. The leaders entering the event,Romain Dumas andLoïc Duval fell to third.Marc Gené was in fourth place and theRebellion trio ofNick Heidfeld,Neel Jani andNico Prost completed the top five after finishing in fourth position.Audi continued to lead the non-scoringToyota in theManufacturers' Championship with five races left in the season.

The24 Hours of Le Mans was first held in1923 after the automotive journalistCharles Faroux, theAutomobile Club de l'Ouest (ACO) general secretary Georges Durand and the industrialist Emile Coquile agreed to hold a test of vehicle reliability and durability. The 24 Hours of Le Mans is considered one of the world's most prestigious motor races and is part of theTriple Crown of Motorsport.^[1]

The ACO moved the 2012 Le Mans schedule forward by one week in order to avoid a date conflict with races in the2012 Formula One World Championship and to allow teams to establish their facilities at theCircuit de la Sarthe close toLe Mans, France.^[2][3] It was the 80th annual edition of the event, as well as the third of eightautomobile endurance races of the2012 FIA World Endurance Championship (WEC).^[4]

After the preceding6 Hours of Spa-Francorchamps,Audi driversRomain Dumas andLoïc Duval led theDrivers' Championship with 43 points, two ahead of their teammatesRinaldo Capello,Tom Kristensen andAllan McNish in second place.Marc Gené was in third position with 25 points, the trio ofMarcel Fässler,André Lotterer andBenoît Tréluyer were in fourth place with19+1⁄2 points andTimo Bernhard was fifth with 18 points.^[5] Audi led the non-scoringToyota in theManufacturers' Championship by 52 points.^[5]

With the introduction of hybrid electric vehicles for the first time at the 24 Hours of Le Mans in 2012, the ACO and the world governing body of motor racing, theFédération Internationale de l'Automobile (FIA), created seven zones on the Circuit de la Sarthe for those cars to recuperateelectrical energy under braking. Each zone was situated 50 m (160 ft) before the entry to a corner. The ACO and the FIA imposed a mandatory limit of 500 kJ (140 Wh) to restrict the amount of energy capable of being harvested by anenergy recovery system between two braking zones and to regulate the capital needed to develop such systems.^[6]

Automatic entries were earned by teams which won their class in the2011 24 Hours of Le Mans. Teams who won Le Mans-based series and events such as theAmerican Le Mans Series (ALMS),Le Mans Series (LMS), and thePetit Le Mans were also invited. Some second-place finishers were also granted automatic entries in certain series. Entries were also granted for the winners of theMichelin Energy Endurance Challenge in both the ALMS and the LMS. A final entry was granted to the champion in the LMS'Formula Le Mans category, and the winner received their invitation in Le Mans Prototype 2 (LMP2). As automatic entries were granted to teams, teams were allowed to change their cars from the previous year to the next, but not their category. Automatic invitations in the two GTE categories could be swapped between the two based on the driver line-ups chosen by those teams. As the ALMS did not separate between the Pro and Am categories, only a single GTE invitation was granted for their class champion.^[7]

On 24 November 2011, the list of automatic entries was announced by the ACO.^[7]Peugeot Sport chose not to accept their automatic invitation as they withdrew from sports car racing in January 2012 due to financial difficulties.^[8]BMW Team RLL and Pegasus Racing were the other two teams who did not take up their entries because both teams elected to focus on their respective series during the 2012 season.^[7]

In conjunction with the announcement of entries for the 2012 FIA WEC, the ACO announced the full 56-car entry list and nine-vehicle reserve list at a press conference in Paris on 2 February.^[9] In addition to the 30 guaranteed entries from the WEC, 5 came from the ALMS, 3 from the LMS, while the rest of the field was filled with one-off entries only competing at Le Mans.^[10]

For the 56th and final entry for the 2012 Le Mans race, the ACO promoted cars which featured advancements in technology, either for performance or ecological improvement. Three projects were submitted to the ACO, with the automatic entry being granted to an American group by the name of Project 56 who developed theDeltaWing concept originally proposed for the AmericanIndyCar Series. The extremely lightweight car features a layout that is far removed from the style ofLe Mans Prototypes. The project was backed byHighcroft Racing,All American Racers and thePanoz Group.^[11] Two other entries had been granted reserve status if the DeltaWing team withdrew: the Swiss-developed GreenGT LMP-H2, which utilized ahydrogenfuel cell to runelectric motors within a Le Mans Prototype style body,^[12] and the FrenchCourage 0.12 usedstored energy to drive electric motors.^[13]

Nine reserves were initially nominated by the ACO, limited to the LMP2 (five) and both of the LMGTE (four) categories.^[10] TheDyson Racing teams withdrew both of theirLola B12/60-Mazda cars from the entry list on 16 April, citing a financial difficulty preventing the team from obtaining the necessary budget to compete at Le Mans and a desire to focus on the ALMS. This promoted theNo. 30Status Grand PrixLola B12/80 and the No. 48Murphy PrototypesOreca 03-Nissan cars to the race entry list.^[14] That same day, the ACO released a revised entry list confirming the withdrawal of the Dyson entries as well as theJetalliance, Hope Racing,Lotus Cars andAston Martin Racing reserve entries. By the event's start, three reserved entries had not been promoted to the race entry.^[15]

A test day was held on 3 June, two weeks prior to the race, and required all race entrants to participate in eight hours of track time divided into two sessions.^[16] A secondLevel 5 MotorsportsHPD ARX-03b forScott Tucker, the No. 32 Lotus Lola B12/80 andIMSA Performance'sPorsche 997 GT3-RSR reserve entries took part.Sébastien Loeb Racing and twoDAMS-entered Le Mans Prototype Challenge Oreca-FLM09s also participated.^[17] Toyota'sStéphane Sarrazin was unable to take part in testing after sustaining facial injuries from a bike accident on the afternoon of 2 June.^[18]

Duval set the fastest lap in the first session at 3 minutes, 27.738 seconds in the No. 3 Audi R18 Ultra.^[19] McNish later improved to a 3 minutes, 25.927 seconds lap in the No. 2 Audi R18 e-tron quattro though he crashed at Tertre Rouge corner with one hour remaining and was unable to continue.^[20] He was followed by Lotterer's No. 1 Audi in second and Duval fell to third. The fastestToyota TS030 Hybrid was fourth courtesy of a lap fromAlexander Wurz and the fastestprivateer LMP1 entry wasDanny Watts' No. 21Strakka Racing HPD ARX-03a car in sixth.^[20] At the end of the first session,Guillaume Moreau crashed the No. 15 OAK Racing Pescarolo car heavily against a concrete barrier in the Porsche Curves, sustaining a fracture to theT12 vertebrae on his spinal cord. He underwent an operation at the Centre Hospitalier Universitaire d'Angers to reduce the pressure on his spinal cord and was ruled out of the race.^[21] His place was taken by former Peugeot driverFranck Montagny.^[22]Olivier Pla's OAKMorgan LMP2 car led in LMP2 asFrédéric Makowiecki in the No. 59Luxury RacingFerrari 458 Italia GT2 was the fastest driver in LMGTE Pro andAllan Simonsen helped Aston Martin to be fastest in LMGTE Am.^[20] Separate crashes from Piergiuseppe Perazzini,Rui Águas,Jordan Taylor,Pierre Thiriet andGianmaria Bruni led to disruptions during the second session.^[23]

After the test several prototype teams, including all Audi, Toyota, Pescarolo and Starworks Motorsports cars participated in an unofficial test on the shorterBugatti Circuit on 6 June to ensure car components were working efficiently before the race.^[24] Official practice was held on 13 June with the full 56-car field on track for four hours.^[16] Audi led from the start once again, with Duval and later Tréluyer setting the early pace. Kristensen went faster before a lap of 3 minutes, 25.163 seconds from Lotterer at the end of the session made him quickest and Audi took the first four places.Kazuki Nakajima was the fastest Toyota driver in fifth and his teammateAnthony Davidson was sixth.^[25] Apowertrain issue stopped the No. 8 Toyota on theMulsanne Straight and it required an engine change.^[25][26] Watts was the fastest LMP1 privateer in seventh andSébastien Bourdais's No. 17 Pescarolo Dome-Judd placed eighth.^[25] The No. 16 Pescarolo car ofJean-Christophe Boullion spun and crashed into a guardrail at 268 km/h (167 mph), damaging his ribs and leaving him unable to compete for the rest of the race meeting.^[27]Tom Kimber-Smith in the No. 44 Starworks HPD ARX-03b vehicle led in LMP2 with a 3 minutes, 39.669 seconds lap, ahead of the No. 38Jota Zytek Z11SN car ofSam Hancock andWarren Hughes' No. 48 Murphy Prototypes Oreca entry.^[25][26] The LMGTE Pro category was led by the No. 97 Aston Martin ofDarren Turner with a time of 3 minutes, 57.036 seconds andPatrick Pilet in the No. 79 Flying Lizard Porsche was fastest in LMGTE Am and was within 1.2 seconds of Turner's pace.^[26] The No. 51 AF Corse Ferrari caused a stoppage afterGiancarlo Fisichella pirouetted and heavily damaged the car's rear-left corner in the Porsche Curves. The ACO and the FIA appliedforce majeure and allowed the car's chassis to be transported to AF Corse's factory inPiacenza for reconstruction.^[28]

The first of three two-hour qualifying sessions to determine the race's starting order through the quickest laps set by each team's fastest driver began late 13 June night under clear conditions.^[16][29] Audi led from the first minutes of the session with a flying lap fromOliver Jarvis in the No. 4 Audi,^[29] followed by Kristensen overtaking Jarvis soon after. He was followed by Lotterer whose final timed lap of 3 minutes, 25.453 seconds earned the No. 1 Audi team provisionalpole position. Kristensen's time put the No. 2 car second and Duval's No. 3 entry finished the session third. The No. 7 Toyota ofNicolas Lapierre was 1.7 seconds adrift of the fastest Audi in fourth.^[30]Mike Rockenfeller's No. 4 Audi took fifth and Davidson's No. 8 Toyota in sixth was the slowest of all the hybrid cars. Watts, driving the No. 21 Strakka HPD, was the top non-hybrid LMP1 vehicle in seventh.^[29]Mathias Beche drove the No. 46 Thiriet by TDS Oreca to provisional pole in LMP2 with a lap of 3 minutes, 39.252 seconds ahead of the Murphy Oreca car ofBrendon Hartley and Kimber-Smith's Starworks HPD vehicle.Keiko Ihara crashed the No. 29 Gulf Racing Middle East Lola car at the Dunlop Curves and was extricated from a barrier by recovery vehicles. The Pro class of LMGTE had Chevrolet lead from the start with the fastest lap set byOliver Gavin in the No. 74C6.R at 3 minutes, 55.910 seconds. Ferrari, Aston Martin and Porsche all had cars within two seconds of the Corvette. Pilet's Flying Lizard Porsche set the pace in LMGTE Am, followed bySean Edwards' No. 75Prospeed Competition car and Simonsen's Aston Martin.^[29] The experimental DeltaWing car driven byMichael Krumm suffered a heavy jolt on a kerb that activated its onboard fire extinguisher and the master electrical switch, disabling the engine.^[31]

The weather was clear for the second session on the evening of 14 June. Duval's Audi R18 Ultra was quickest in the session with a lap of 3 minutes, 24.098 seconds on 30 minutes to go and passed Lotterer's No. 1 Audi for provisional pole position. McNish's No. 2 car finished the session third at the conclusion of a final six-lap stint as Davidson prevented Audi from taking the first four positions in the No. 8 Toyota. The No. 4 Audi ofMarco Bonanomi fell to fifth and Toyota's No. 7 entry driven by Nakajima dropped to sixth after Lapierre lost control of its rear and spun into some grass entering the Ford Chicane. Watts' Strakka HPD improved its best lap to ensure it remained the fastest non-hybrid LMP1 vehicle in seventh withNeel Jani's No. 12 Rebellion Lola-Toyota eighth.^[32] One second covered the first six vehicles in LMP2 as Pla gave OAK's Oreca car provisional pole in class at the session's conclusion with a time of 3 minutes, 38.598 seconds despite a driver error into a gravel trap at Indianapolis corner.Nelson Panciatici's No. 26Signatech car was second. In LMGTE Pro, Makowiecki moved the No. 59 Luxury Ferrari to the provisional category pole position. Turner helped Aston Martin to finish the session second andTommy Milner's No. 74 Corvette took third.^[33] The No. 58 Luxury Ferrari was the fastest LMGTE Am car of the session yet it was more than 1.2 seconds behind the Flying Lizard Porsche's pole lap.^[32]

Notes:

• ^1 —The No. 16Pescarolo 03-Judd started from the pit lane after a change of engine overran into the race.^[39]

The cars took to the circuit on the morning of 16 June for a 45-minute warm-up session on a waterlogged track. The No. 3 Audi driven by Duval set the fastest lap of 4 minutes, 3.933 seconds with the sister No. 2 car of Capello second and the pole sitting No. 1 of Lotterer third.^[40] Jarvis' No. 4 Audi was fourth and the quickest Toyota was fifth after a lap from Wurz. The fastest LMP2 lap was recorded by the No. 42Greaves Motorsport Zytek Nissan car ofLucas Ordóñez. AF Corse's No. 51 Ferrari driven byToni Vilander was the fastest car in LMGTE Pro whileJoël Camathias of JWA-Avila helped Porsche to lead in LMGTE Am.^[41][42] During the session, where several carsaquaplaned on the track,Marc Rostan spun the No. 29 Gulf Racing Middle East Lola car on the start/finish straight andJan Charouz beached the No. 25 ADR-Delta Oreca vehicle in a gravel trap at Dunlop Curve leading to the session being stopped for ten minutes.^[40]

The weather was dry and sunny before the race with an air temperature between 10.5 to 21 °C (50.9 to 69.8 °F) and the track temperature from 15.5 to 26 °C (59.9 to 78.8 °F).^[43] Approximately 240,000 spectators attended the race.^[4] TheFrench tricolour was waved at 15:00Central European Summer Time (UTC+02:00),^[16] byTakeshi Uchiyamada, the vice president and director of Toyota, to start the race,^[44] led by the starting pole sitter Lotterer.^[45] A total of 56 cars planned to take the start but the No. 16 Pescarolo 03-Judd car underwent an engine change in the pit lane after it failed during the warm-up session and the No. 21 Strakka HPD vehicle had agearbox oil leak caused by a seal connecting thedriveshaft and the gearbox failing. Lotterer maintained his lead on the opening lap and he pulled away from the rest of the field.^[39] McNish's No. 2 Audi overtook Sarrazin's No. 8 Toyota for third and he held off a counter-challenge from Sarrazin to keep the position. Light rain that fell on the north section of the track did not affect the race.^[46]

In LMP2, John Martin led the first nine laps until Pla's OAK car passed him during pit stop rotation. The No. 59 Luxury Racing Ferrari ofJaime Melo fell to fifth in the opening laps as LMGTE Am began as a multi-car battle between representatives of Porsche, Ferrari and Aston Martin with the lead of the class changing multiple times during the first hour.^[46] The LMGTE classes continued to be closely contested in the second hour with the No. 97 Aston Martin ofStefan Mücke, AF Corse's No. 51 Ferrari of Bruni and Gavin's No. 74 Corvette duelling for the head of the Pro category. Kimber-Smith was lapping faster thanSoheil Ayari's No. 49 PeCom vehicle in the LMP2 category at the time and he moved the Starworks team to second in class. The hour had the first retirement with Rostan's No. 29 Gulf Racing Middle East Lola car sustaining a broken front-left wheel alignment from an accident leaving the Porsche Curves. Pilet and laterSpencer Pumpelly's No. 79 Flying Lizard car took a clear lead in LMGTE Am after the No. 99 Aston Martin of Simonsen developed a misfire.^[47][48] LMGTE Pro continued to be a close battle between Milner's No. 74 Corvette, Turner's No. 97 Aston Martin and Bruni's No. 51 AF Corse Ferrari with the three cars nose-to-tail on the circuit and the lead changed frequently. The Ferrari was subsequently able to remain on track for longer than its competitors during a sequence of pit stops.^[49]

Nearly four hours into the race, Kristensen's No. 2 Audi returned to the garage so that the team's mechanics could remove a large amount of rubber debris lodged in its right-rear suspension arm and created a vibration. Kristensen returned to the race in fifth position and a routine pit stop for Duval's No. 3 car promoted the Toyota cars of Lapierre and Buemi to second and third.^[50][51] Although Toyota had less fuel economy than Audi,^[50] Buemi and later his teammate Lapierre were able to attack in the fourth hour and lowered Tréluyer's lead to twenty seconds.Jody Firth in the No. 48 Murphy Prototypes Oreca-Nissan vehicle passedRyan Dalziel's Starworks HPD car for third in LMP2 and he pulled away from Dalziel to lead him by twenty seconds. Lapierre sustained damage to the No. 7 Toyota's right rear wing endplate which later detached and he continued in second position.^[52] Not long after Dumas waslapping the LMGTE-Am leading No. 79 Flying Lizard Porsche ofSeth Neiman at the first Mulsanne Straight chicane and heundersteered heavily into a tyre barrier with the No. 4 Audi's front-right corner.^[50][53] The car sustained heavy damage to its front bodywork,^[53] and required a 26-minute and 34-second pit stop to replace it and dropping the car down the race order.^[54] The fifth hour ended with Lapierre prevailing against Tréluyer in a duel for the lead.^[53]

At the start of the sixth hour Davidson in third was lapping Perazzini's No. 81 AF Corse Ferrari when the left-rear of the No. 8 Toyota made contact with the front-right of the Ferrari at the end of the Mulsanne Straight.^[55] The Toyota rotated through 360 degrees,^[56] lifted into the air after its right-rear wheel detached in the collision with the Ferrari and allowed air to penetrate its floor, It struck the tarmac with its front-left corner and hurtled upright at high speed towards a tyre wall at Mulsanne corner. Perrazzini's Ferrari made heavy side contact with an armco metal barrier that deformed it and the vehicle was turned onto its roof. Thesafety cars were deployed to slow the race as marshals worked for 70 minutes to replace and repair the damaged barriers and extricate the two cars from the track.^[54] Both Davidson and Perrazzini vacated their vehicles without external assistance;^[55] Davidson was transported to a local hospital from the circuit's medical centre complaining of shock and back pain. Davidson fractured his T11 and T12 vertebrae while Perrazzini was unhurt.^[57]

Half a minute after racing resumed the overall leading No. 1 Audi of Fässler was delayed by slower traffic, causing Nakajima's No. 7 Toyota to collide with the left-hand corner of the No. 0 DeltaWing car ofSatoshi Motoyama and sent the latter into a concrete barrier beside the circuit.^[58] The DeltaWing sustained damage to its steering arm, powertrain and rear bodywork; track marshals pushed it behind the wall to allow mechanics from Highcroft Racing to advise Motoyama on how to repair the car. He spent 90 minutes repairing the car with garage equipment though he was unable to make it mobile and retired.^[59][60]Brendon Hartley was the fastest LMP2 driver at the time and he brought the No. 48 Greaves Oreca to the lead of the category. The No. 7 Toyota was driven into the pit lane for repairs to its rear and the crash promoted Audi to the first three positions.Pedro Lamy in the No. 50Larbre Compétition got involved in a battle withNicolas Armindo's No. 67 IMSA Performance Porsche for the lead of LMGTE Am.^[58]Maxime Martin returned OAK's No. 24 Oreca car to the lead in LMP2 until a puncture during his first lap out of the pit lane after a routine stop allowed the No. 48 Murphy Oreca-Nissan vehicle of Hughes back to the front of the category.^[61]

Lotterer had an anxious moment when he made a driver error during the first third of a lap in the No. 1 Audi; he returned to the track without losing the overall lead. Further down the field the fuel efficiency of the Ferrari 458 Italia allowed the No. 51 AF Corse of Bruni to remain in contention with the LMGTE Pro leading Corvette of Milner.^[62] As it turned 17 June, the No. 48 Murphy Oreca-Nissan relinquished the lead of LMP2 when driver Hughes entered the pit lane with a right-rear puncture that sent the car into a spin at the exit to Arnage corner and caused damage to its rear wheel arch and deck.^[63][64] Pla retook the class lead in the No. 24 OAK Oreca until he too was forced to slow and enter the pit lane with a sudden loss of oil pressure that was unable to be rectified and forced the car's retirement,^[65] returning the No. 44 Starworks HPD car of Kimber-Smith and later Dalziel to the category lead.^[63] In the eleventh hour, Westbrook had just relieved Milner in the No. 74 Corvette when its left-rear tyre detached in the Dunlop Esses and slowing him for the rest of the lap en route to the pit lane for repairs to the car's bodywork and underwent a change of brake discs.^[66] The car relinquished the lead of LMGTE Pro it had held for 66 consecutive laps to the No. 51 AF Corse.^[67]

Toyota lost its one remaining entry when the No. 7 car retired after 10½ hours with an engine failure.^[4] The No. 74 Corvette emerged on the track soon after though it was once again involved in an incident when Westbrook crashed at the first Mulsanne Straight chicane and necessitating repairs to its bodywork and a change of differential and halfshaft. A major accident for Frankie Montecalvo's No. 58 Luxury Racing Ferrari caused the car to retire with heavy left-hand side damage and its front wing removed.^[66] As the race approached half distance, the No. 1 Audi of Fässler led Kristensen's No. 2 car by 40 seconds before a driver change, Bonamoni's No. 3 entry was in third position and the recovering No. 4 driven by Dumas was fourth after contact with the No. 70 Larbre Corvette at the Ford Chicane. Makowiecki lost ground to the LMGTE Pro leading AF Corse Ferrari of Fisichella in the No. 59 Luxury Racing car after a driver error put him into a gravel trap at Indianapolis corner.^[68] McNish took over the No. 2 Audi and lapped in the 3 minutes and 30 seconds range to which Fässler's No. 1 entry responded to stabilise a gap to 1 minute and 20 seconds at the conclusion of the 13th hour.^[69]

In the early morning the No. 1 Audi of Fässler spun in the Porsche Curves and made contact with the rear of the car against a barrier, relinquishing first place to McNish's No. 2 car.^[70] During this period a broken left-rear transmission on Hartley's No. 48 Murphy Oreca-Nissan failed and caused one of the car's rear wheels to lock before track marshals pushed it towards the pit lane for it to be retired from the event.^[71]Abdulaziz Al Faisal spun and crashed backwards against a concrete barrier in the Porsche Curves causing enough damage to retire the vehicle and required the deployment of the safety cars for the second time in the race.^[70] When racing resumedHarold Primat's No. 13 Rebellion Lola car spun on cold tyres exiting the Porsche Curves; he avoided contact with a circuit barrier. The car lost a large amount of time while it was recovered by track marshals and Primat continued in sixth overall. The safety cars allowed Lotterer's No. 1 Audi to return to the lead after McNish entered the pit lane for a routine pit stop.^[72] Mücke, holding second place in LMGTE Pro, lost control of the No. 97 Aston Martin, went straight on and made contact with the car's right-hand side against a tyre wall to the right of the track.^[73] The car sustained minor damage and after repairs which dropped it four laps, returned to the track third in class.^[74] AF Corse had their lead in LMGTE Pro further strengthened when Makowiecki's Luxury Racing Ferrari picked up a right-rear puncture and required the team's mechanics to replace it.^[73][74]

Duval in the No. 3 Audi became the lead challenger to the No. 12 Rebellion Lola car, twice resetting the race'sfastest lap and passing the Rebellion for fourth overall.^[75]Brian Vickers made minor contact against a wall at Tetre Rouge corner and the No. 71 AF Corse Ferrari sustained a left-front puncture. As he entered the pit lane, the front-left wheel caught fire, which fire marshals extinguished. The car was transported into the garage for repairs to its bodywork.^[76] Over three hours after reclaiming the race lead, Fässler encountered the No. 74 Corvette, which spun at Mulsanne corner. He damaged the No. 1 Audi's rear bodywork against a barrier in avoidance. Audi told Fässler to remain on the circuit until his next scheduled stop to replace the damaged component. Repairs took more than two minutes to complete and allowed Kristensen's No. 2 car to reclaim the lead following a pit stop for fuel. Kristensen overhauled Fässler in a duel for the lead on the Mulsanne Straight after a driver error sent the latter into a gravel trap.^[77] Separate pit stop strategies for the No. 1 and 2 Audi cars saw the lead exchange several times, while the No. 13 Rebellion car was forced into the pit lane for aclutch change and forfeiting sixth place to the No. 22JRM HPD vehicle.^[78] Ayari, driving the No. 49 PeCom Oreca, held second place in LMP2 until he ran wide at Indianapolis corner and beached the car in a gravel trap. The car dropped to fourth after recovery vehicles extricated it from the gravel and Ayari made a pit stop to remove debris from it.^[79]

Bonanomi's No. 4 Audi twice stopped on the circuit with a transmission fault that he rectified by resetting theignition system and kept the car in third position.^[80][81] Not long after an accident forSimon Dolan's No. 38 Jota Zytek in the Porsche Curves caused its retirement in the garage due to extensive damage to its rear.^[81] The race-leading No. 1 Audi of Tréluyer spun at the entry to the pit lane as he slowed to comply with the pit lane speed limit. He lost the lead to McNish's No. 2 car who extended it to 47 seconds.^[82] Audi suffered two accidents in the 22nd hour that warranted the third deployment of the safety cars. Gené in the No. 3 Audi repeated his co-driver Dumas' accident from the fifth hour, understeering into a wall at the exit to the first Mulsanne Straight chicane and damaged the car's front bodywork and front-right suspension. McNish's No. 2 car had rear oversteer while lapping the No. 59 Luxury Racing Ferrari and punctured a hole on an armco metal barrier in the Porsche Curves. Repairs to the No. 2 Audi dropped McNish one lap behind Lotterer and Gené fell behind the No. 13 Rebellion car in fourth place.^[83][84] After racing resumed, Anthony Pons' No. 76 IMSA Performance Porsche ceded the lead of LMGTE Am to Lamy's No. 50 Larbre Corvette which it maintained to the finish to earn the team's fifth victory in the class after Pons sustained a left-rear puncture on the final lap.^[85][86]

The No. 1 Audi R18 e-tron quattro of Fässler, Lotterer and Tréluyer maintained the race lead without trouble for the final two hours of the race,^[4] taking the trio's second consecutive win and Audi's eleventh overall in a distance of 5,151.8 km (3,201.2 mi) and 378 laps.^[87] Audi completed a sweep of the podium positions with the No. 2 and No. 4 cars in second and third.^[4] The Audi R18 e-tron quattro was the first hybrid electric and non-permanentfour-wheel drivetrain vehicle to win the 24 Hour race.^[4][87] The Starworks Motorsport team was undaunted in LMP2 and maintained the first-place position it had held for 215 consecutive laps to win,^[67] earning Kimber-Smith his third victory in the class and Dalziel and Pottolicchio's first.^[88] The Thiriet by TDS Racing and PeCom Racing teams were second and third in LMP2. AF Corse held their three-lap lead over Luxury Racing in LMGTE Pro and took their first class win. It gave Bruni his second category win, and Fisichella and Vilander's first. Aston Martin came third in the category. The IMSA Performance team were able to secure a second-place finish in LMGTE Am after the team's late event puncture and theKrohn Racing squad followed in third.^[89] There were eighteen outright lead changes amongst three cars during the race. The No. 1 Audi's 326 laps led was more than any other car.^[67]

The top three teams in each of the four classes appeared on the podium to collect their trophies and spoke to the media in the later press conferences.^[16] Lotterer said Audi's victory over Peugeot in the 2011 edition provided him with the confidence to challenge Toyota, "For me, I'm more new in Le Mans so to be in that situation was amazing, so this year we had a bit more confidence within the team. We know we can trust each other even more and this gave us good potential. But you come to Le Mans and you can't expect to win, you just do your best and hope that it will work."^[90] McNish apologised for the accident that caused the crew of the No. 2 Audi to lose a chance at victory, "I'm sorry for our team: Dindo, Tom, the engineers and the mechanics. They did a perfect job throughout the race. Despite a few problems we were in contention for victory up to my accident."^[91] Capello revealed that he said to McNish that the crash could have occurred to any driver, "For sure I felt disappointed when I saw the car in the wall, but as a driver immediately my thoughts went to Allan because I know he was giving 100% to try to close the gap as much as possible to the #1 car."^[92]

Davidson was flown back to his home in Oxford on 20 June to begin a three-month recovery period.^[93] He attributed the design of his race seat and head rest to saving him from paralysis, "It held me, supported me and arguably was the thing that saved me from further compression and maybe the worst case scenario of being paralysed now instead. When you look at everything involved, I think I got away with it the lightest I was ever going to."^[94] Members of the Toyota team went to the Nissan garage to apologise for the collision that resulted in the retirement of the DeltaWing.^[95] The team principal,Pascal Vasselon, stated Toyota's pace in the first half of the race was a realistic of what it could achieve, "We were not looking for an aggressive start and leading for 10 minutes. I know some people were expecting us to try to do that at the start, but no. The drivers knew they had to be safe at the start, then at the beginning the balance was not perfect. It was changing, the track was changing. We started on a very green track [because of the rain overnight] and it's important to be balanced for when the grip builds up, that was our target."^[96]

Due to the result of the event, McNish, Kristensen and Capello moved to the lead of the Drivers' Championship with 77 points, 6½ ahead of the race winners Lotterer, Fässler and Tréluyer in second place. Dumas and Duval fell from first to third with 67 points, Gené stood in fourth position with 49 points and the Rebellion trio ofNick Heidfeld, Jani andNico Prost rounded out the top five with 42½.^[5] Audi continued to maintain their lead over the non-scoring Toyota in the Manufacturers' Championship with five races left in the season.^[5]
