Graham Rahal leads Motul Petit Le Mans under yellow at the halfway point for Acura Team Penske.

GT Daytona Championship leaders Paul Miller Racing lead in class with Madison Snow currently aboard the No. 48 Lamborghini Huracan GT3 followed by Ben Keating’s No. 33 Mercedes-AMG GT3 and Alvaro Parente in the No. 86 Meyer Shank Racing Acura NSX GT3.
The No. 5 AXR Cadillac is mired back in ninth after an off track excursion for Filipe Albuquerque midway through the fourth hour which dropped them off the lead lap.
The car did sustain minor front end damage which was rectified under the yellow.
The No. 55 Mazda, which had recovered from losing a wheel under yellow earlier in the race, was handed another setback when it sustained damage to the rear of the machine after contact with a GTLM Porsche.
From the GTD class, the No. 93 MSR Acura went behind the wall in the fifth hour with a suspected oil leak and has been retired from the race, while he No. 73 Park Place Motorsports Porsche 911 GT3 R lost close to an hour with a gearbox issue.
An early casualty of attrition, the No. 6 Acura is back on track, albeit many laps down, after undergoing extensive repairs to damage sustained when Juan Pablo Montoya went off course earlier in the race.
