With five hours remaining in the 2017 6 hours of Mexico, Porsche holds a 1-2 at the head of the field, with the #2 919 Hybrid of Brendon Hartley leading Nick Tandy in the #1 from Pole, in what has been a relatively comfortable hour for the German team.
Behind, the two Toyota TS050s are third and fourth, the #7 of Mike Conway leading the #8 of Sebastien Buemi. The pair are 25 and 29 seconds off the leader respectively, unable to match the pace of the 919s through the relentless traffic.
In LMP2, the #31 Vaillante Rebellion ORECA leads the way, after the first round of stops, the Bruno Senna taking the start and gapping the field in the first stint. But by being one of only two cars in the field to change drivers in the pits, its 26-second lead is down to 4.3 with Nicolas Prost now behind the wheel.
Second is Alex Lynn in the G-Drive Racing ORECA, who fell back from Senna after a lengthy battle for the place with Pole-sitter Nicolas Lapierre, who slipped back to second place on the first lap, and then third 40 minutes into the race.
Third and fourth in the class are the two Jackie Chan DC Racing ORECAs, with the #38 of Oliver Jarvis ahead of the #27 of Tristan Gommendy. After Lapierre handed the Alpine over to Gustavo Menezes, the A470 is now down to fifth.
GTE Pro is led by the Pole-sitting #71 AF Corse Ferrari of Sam Bird, the Britain unable to create a healthy margin though, and instead having to defend hard at the end of the hour from the #95 Aston Martin of Marco Sorensen.
Behind in third is the #67 Ford GT of Harry Tincknell, with the sister #66 Ford of Stefan Mucke fourth.
The best of the Porsches – the #91 of Richard Lietz – is fifth, the sister car in the wars and seventh during the hour after a collision with the Clearwater Racing Ferrari of Mok Weng Sun at Turn 1.
Last in the class, and last overall is the #97 Aston Martin, which suffered from braking issues which forced Darren Turner to lose almost 20 minutes in the box for repairs after falling down the order on-track.
Aston Martin’s #98 Am class Vantage meanwhile, is having better fortunes, Pedro Lamy charging to the lead in the hour, getting past Pole-sitter Christian Reid and charging off into the distance. The lead for the Portuguese veteran is now 22 seconds.
An impressive first stint from Mike Wainwright kept the Gulf Racing UK Porsche third, in front of the #54 Spirt of Race Ferrari in fourth.
Last in the class is the GTE Am points-leading Clearwater Ferrari, which has had a disastrous outing so far after Sun’s contact with the #92 Porsche of Michael Christensen at Turn 1. The Singaporean Ferrari is now a lap down on the field after serving two subsequent drive-through penalties, one for the contact, and a second for speeding in the pit lane.
