Most of the quick times in DPi were set early in the session with top times from the top three all being set before they completed six laps.
Neither the #55 Mazda RT24P nor the #77 Mazda RT24P participated in the session. The #55 Mazda spent most of the session having its rear assembly replaced, while the pole-sitting #77 Mazda was undergoing what it appeared to be routine maintenance.
In LMP2, the pole-sitting #52 PR1/Mathiasen Motorsports ORECA 07 set the quickest time. Gabriel Aubry set a time of 1:37.084.
Colin Braun in the #81 DragonSpeed ORECA 07 ended the session in second and Ryan Dalziel in the #8 Tower Motorsports ORECA 07 finished the session in third.

Mathieu Jaminet set the car’s quickest time, a 1:43.301.
The #24 BMW M8 GTE ended the session in second. Augusto Farfus set the quickest time of 1:43.611. The #24 BMW carried the banner for BMW for most of the session while the sister #25 BMW spent much of the session in the garage after undergoing repairs for a broken fuel pump.

The #16 Wright Motorsports Porsche 911 GT3 R led a Porsche 1-2 in GTD. Klaus Bachler set the quickest time in that car, a 1:46.128. That car ended the session in the infield, however, after pulling off the circuit and stopping amongst the RVs, it was not clear what the problem was.
The pole-sitting #9 Pfaff Motorsports Porsche 911 GT3 R ended the session in second. Dennis Olsen set a best time of 1:46.203. There was also drama for the #9 Porsche, it coasted into the pits without power and was pushed into the box.
