The fourth full-course caution waved at the five-hour, 41-minute mark for a Turn 1 incident involving two DPis. While Wayne Taylor Racing’s Kamui Kobayashi and most of the other DPis opted to pit under the yellow, Pipo Derani stayed out to give the No. 31 Whelen Engineering Cadillac the lead.
That move eventually gave the 31 team five points for leading the opening segment of the Michelin Endurance Cup. It also illustrates why the Action Express Racing team has won the Cup each year since its inception in 2014.
Prior to the caution, Kobayashi led the green-flag section of the hour after taking over for Fernando Alonso in the No. 10 Konica Minolta Cadillac DPi. He was second at the six-hour mark, followed by Juan Pablo Montoya in the No. Team Penske 6 Acura, the No. 77 Mazda driven by Timo Bernhard and Ricky Taylor in the No. 7 Acura.
DragonSpeed continued to lead LMP2 with Roberto Gonzalez behind the wheel, while in GTLM, Oliver Gavin in the No. 4 Corvette and in GTD, Felipe Fraga continued to lead for Team Riley Motorsports in the No. 33 Mercedes-AMG GT3.
The biggest incident occurred at the 5:41 mark, when Mark Kvamme spun the No. 52 PR1 Mathiasen Motorsports ORECA Gibson in Turn 1. Kvamme was stranded in the center of the track and watched most of the field take evasive action. Juan Piedrahita had contact in the No. 84 JDC-Miller Motorsports Cadillac DPi, going to the garage with damage.
