Audi took the lead of the Le Mans 24 Hours as the leading Toyota his trouble at the front.
Kazuki Nakajima appeared to have the threat of the #2 Audi under control after Stephane Sarrazin had struggled to prevent Andre Lotterer and then Benoit Treluyer from making inroads into its lead.
However, the Toyota then came to a halt near Arnage corner with an electrical problem, and was officially retired from the race shortly after.
Behind the new leader, Brendon Hartley's Porsche continued to run ahead of Lucas di Grassi in the #1 Audi, which had fallen out of a podium spot when it suffered fuel injection problems .
The second #14 Porsche lost its top five spot to the #8 Toyota, which continued its recovery following Nicolas Lapierre's crash early in the race.
The #35 OAK-run Ligier maintained its lead in LMP2 with Jann Mardenborough at the wheel, with the Signatech ORECA of Oliver Webb giving chase in second.
Also in the LMP2 class, Karun Chandhok's Murphy Prototypes team was forced into an early retirement in the tenth hour after a steering problem left the #48 Oreca Nissan stranded out on the circuit. This is the Indian's first retirement at Le Mans (in three attempts).
Darren Turner repassed Giancarlo Fisichella to ensure Aston Martin retained the lead in GTE Pro, and the British marquee also heads the Am division as well.
Turner had dropped behind Fisichella by virtue of taking on tyres in a pitstop right at the end of the previous hour but was quickly catching the AF Corse Ferrari 458 Italia when he rejoined the track.
A six-second gap was reduced to nothing within half an hour and soon after Turner breezed past on the Mulsanne straight to, not for the first time in this race, wrest the lead away from the Italian.
A pitstop for Fisichella, during which he took on tyres, coupled with a stop for Turner that involved him double-stinting his rubber, extended the Briton's advantage further.
Long-time frontrunner Corvette's lead #74 C7.R dropped to fourth behind the #92 Manthey Porsche after spending time in the garage changing brakes, though the team insisted this was pre-planned and maintained it was in the running for victory.
While the #95 Aston Martin continues unabated in GTE Am, the order behind it has changed. The #61 AF Corse Ferrari is now second, with the #88 Proton Competition Porsche third after the SMP Ferrari was wheeled into the garage twice with mechanical problems.
