Porsche LMP Team finished the opening practice session of the 2017 6 Hours of Mexico 1-2 atop the times. Fastest of the 919 drivers was Andre Lotterer in the #2 Porsche 919 Hybrid, the German setting a 1:27.026 late in the session, to go just over half a second quicker than the sister #1 Porsche which ended up second after a best time from Earl Bamber.
Behind were the two Toyota Gazoo Racing TS050s, which early on in the session ran fastest. The TS050s were quickest when the track was at it wettest, after a rain shower prior to the session meant the times tumbled throughout as conditions improved.
The best time from the two Toyotas was a 1:28.029 by Mike Conway in the #7 to go third and a second off the fastest time set by Lotterer. The #8 meanwhile, was two seconds off the ultimate pace in fourth after Sebastien Buemi’s best efforts.
Fastest in LMP2 was the #36 Signatech Alpine A470 of Nicolas Lapierre, Gustavo Menezes and Andre Negrao. Lapierre set the fastest time in the car, a 1:34.556, which in the end was three tenths faster than Bruno Senna in the #13 Rebellion ORECA 07, which ended up second in the now all-ORECA class.
Completing the top three was the G-Drive Racing 07, Roman Rusinov the fastest driver for the Russian-flagged team with a 1:35.506 tour of the 4-km circuit.

Fastest of the two 911s in the class was the #77 Dempsey Proton Racing example, after Matteo Cairoli reeled off a 1:42.461, to put the team ahead of the Gulf Racing UK squad which finished just a tenth off. In the end, Ben Barker was the quickest driver in the car, the Britain setting a 1:42.576.
