Andre Lotterer headed the field by just under two-hundredths of a second ahead of team-mate Thomas Laurent, followed by the Toyota Hybrids of Kazuki Nakajima and Kamui Kobayashi in third and fourth respectively.
Both SMP BR Engineering BR1 AER entries finished fifth and sixth.
In addition to being out-gunned by the non-hybrids for the first time this season, the number TS050 spun when Kobayashi was forced to avoid a collision with the TF Sport GTE-Am Aston Martin.
The non-hybrid entries have been maxing out performance to bridge the gap to the Toyota’s and the race will be no exception, with both drivers and teams finding extracting the last tenth from pit-stops a precarious exercise.
In LMP2, DragonSpeed’s Anthony Davidson put the number 31 Oreca 07 Gibson a tenth ahead of Signatech Alpine’s Andre Negrao, followed by the Jackie Chan DC Racing entries.
Marco Sorensen put Aston Martin on top of GTE Pro by three tenths over Olivier Pla in the number 66 Ford GT, with the number 92 Porsche of Kevin Estre rounding out the top three.
Ferrari teams Clearwater Racing and Spirit of Race again dominated GTE-Am, with this time Matt Griffin heading Giancarlo Fisichella.
