91 Porsche 911 was vacated after regular driver Michael Christensen missed the Spa race because of a United SportsCar Championship commitment, while Richard Lietz moved to the team's No.

[2] Ferrari's factory team AF Corse entered a second car in LMGTE Am which was driven by Duncan Cameron, Alex Mortimer and Matt Griffin.

[16] Audi had won the preceding 6 Hours of Silverstone with Lieb, Dumas and Jani finishing in second place, while Davidson, Buemi and Nakajima came in third position.

Conditions deteriorated as the session advanced, and several cars elected not to improve their quickest times to avoid driving off the track after going through standing water.

[26] Lotterer set the quickest time of the weekend so far at 1:57.368 recorded in the session's final minute,[27] and was 0.011 seconds faster than the second-fastest car of Hülkenberg.

[28] A brief full course yellow flag was displayed when Bachler's back-end collided with the Pouhon corner tyre barrier,[27][29] while Turner avoided going into the Les Combes wall and was temporarily beached in the turn's gravel trap.

[31] Bernhard took over from Hartley and recorded a lap that was 0.027 seconds faster than the latter lowering the car's two-lap average time to 1:54.767 clinching pole position.

[31][32] The pair were two-tenths of a second faster than the second-place qualifiers, Howson and Lapierre, and held the class pole position until Canal's lap.

43 car took third in the category,[35] while the second G-Drive Racing entry was fourth, with fifth-placed qualifier Tincknell recording the session's best class individual lap time.

[37] KCMG's No 47 car had its qualifying lap times disallowed after it was discovered in post-qualifying scrutineering that the vehicle's skid block had insufficient rigidity and had been excessively flexible.

Jota Sport was issued with a drive-through penalty after its car was adjudged to have jumped the start and rejoined in sixth in LMP2, allowing Bird to the front of the category.

[44] Tandy drove to the inside of Estre to lap him, but made head-on contact with his car and went straight into the Pif Paf corner barrier.

30 Extreme Speed Motorsports car into the team's garage to allow his mechanics to replace a broken boost line falling to the rear of the LMP2 field.

[50] Tandy stopped his Porsche briefly at the pit lane entry, while Bonanomi went wide driving up to Radallion corner battling Wurz for sixth.

[51] Bernhard was caught by Duval and used his car's hybrid boost system on the Kemmel straight, moving ahead of the German under braking for Les Combes corner.

This prompted a localised yellow caution flag, and enabled Aleksey Basov and Khaled Al Qubaisi to inherit second and third places in LMGTE Am.

[57] Bruni reduced the time deficit to Alex MacDowall and passed him by using the Bus Stop chicane kerbs to claim the LMGTE Pro lead.

Lapierre moved ahead of Paul-Loup Chatin to take over fourth place in LMP2, while Jani reduced the time deficit to two seconds in arrears of Tréluyer on lap 154.

[48] Following the first free practice crash between Nakajima and Jarvis, Davidson called for cars to be equipped with brighter flashing rain lights and that what happened to his co-driver was "every driver's worst nightmare".

[66] Toyota's technical director Pascal Vasselon believed Nakajima's lack of reaction time along with the absence of flashing rain lights contributed to his injury.

[66] In early June, the sport's governing body, the Fédération Internationale de l'Automobile (FIA) and the ACO, required all Le Mans Prototype cars carry additional flashing rain lights at the rear of their cars from the 24 Hours of Le Mans onward after the FIA's Endurance Committee observed their usage under wet weather conditions and felt there was an improvement in visibility.

[68] The result meant Lotterer, Fässler and Tréluyer increased their Drivers' Championship advantage to 14 points ahead of second-placed Lieb, Jani and Dumas.
