The #14 Porsche returned to the race after a lengthy stop – the car’s 194th lap officially taking 18 and a half minutes to complete; Romain Dumas telling Shea Adam on RLM that the problem was again fuel-pressure related.
Further down the pitlane, the good run for the #72 SMP Ferrari looked to be at an end as the team worked on the front left and rear right wheel-wells. Andrea Bertolini sat patiently in the car as the work continued, but the Ferrari continued to slip down the order.
The #52 RAM Ferrari was suffering still further problems, with now the gearbox undergoing major repairs; and the #74 Corvette was in for a full brake disc, caliper and pad change.
Darren Turner was again closing in on the GTE-Pro lead in the #97 Aston Martin Vantage, having closed to within four seconds after 186 laps – a gain of 10 seconds since his last stop. The #72 SMP Oreca made a stop for new bodywork – the front left light cluster being absent – and Anton Ladygin took the car back into the race at the same time as the #72 Ferrari rejoined.
The class leads at 04:30 were two minutes (P1), 2:52.925 (P2), 0.365s (GTE-Pro) and one lap (GTE-Am). Moments later, Turner took the Pro lead from Fisichella.
Jann Mardenborough put in yet another PB – 3:38.676 – as his impressive run continued. One lap later, he pitted the #35 Ligier for new tyres and carried on.
The leader pitted at 04:38, with Kazuki Nakajima taking control of the #7 Toyota after a triple stint for Stéphane Sarrazin. Tristan Gommendy, meanwhile, pitted the #46 Thiriet Ligier from third in LMP2.
Turner pitted for fuel on (its) Lap 192, but still held the lead over Bruni.
But the hour ended in dramatic circumstances as the leader was reported to have stopped at Arnage. Treluyer now led in the #2 Audi.
