Filipe Albuquerque of the #10 Acura led after seven hours completed at the IMSA SportsCar Championship’s 27th running of Petit Le Mans.
With the 10-hour IMSA season finale heading into the latter half of the race, the day drew to evening and eventually night-time.
This meant that the clear, blue skies and ambient temperatures begun to fall naturally.
Furthermore, tyre management is affected in the way that the performance will differ slightly in the nighttime in comparison to the daytime.
At the turn of the sixth racing hour, the fight for the overall lead in the GTP category was still hot as ever.
Both Porsche Penske and Wayne Taylor Racing with Andretti Acura cars proved to be the strongest team effort so far.
The top-four ran as Nick Tandy’s #6 Porsche 963, followed by teammate #7 Porsche of Dane Cameron and Brendon Hartley’s #10 Acura ARX-06.
Unfortunately for Tandy, he unintentionally nudged off the #47 Cetilar Racing Ferrari 296 GT3 – of Roberto Lacorte – at Turn 3.
From the lead, Tandy served his subsequent drive-through penalty which put him in third whilst Cameron took the lead.
Hartley, however, maintained strong pace so as to take the lead from Cameron at the chicane before Tandy overtook Cameron.

Albuquerque held the lead in the #10 WTRAndretti Acura, followed by Mathieu Jaminet’s #6 Porsche Penske.
The other Porsche Penske, the #7, of Matt Campbell took third position.
