CGR driver Sebastien Bourdais propelled the #01 Cadillac V-LMDh to first position shortly after the end of the 15th hour after passing the Porsche of Nick Tandy, who had been struggling on old tires and subsequently headed to the pitlane for fresh rubber.
This initially established a Cadillac 1-2 at the head of the field, with Alex Lynn trailing Bourdais in the #02 car, but MSR moved back up to second when Tom Blomqvist passed Lynn’s teammate Richard Westbrook in the 16th hour.
