There was a red flag within three minutes of the start of the session when the Winward Racing Mercedes AMG GT3 stopped at Turn 3 before continuing under its own power, and during the brief stoppage it was extended as a result of Ryan Dalziel’s Era Motorsport LMP2 car stopping at Turn 4.
Just past the quarter-hour mark, the Chip Ganassi Racing Cadillac DPi-V.Rs of Sebastien Bourdais and Alex Lynn sat 1-2 at the top of the times, on 1min32.4sec laps, just 0.004sec apart, despite Lynn having a lap invalidated for a track limits violation. Then Bourdais trimmed a further three tenths off his lap. While the CGR cars sat in the pits, Pipo Derani moved the Action Express Racing #31 Whelen Engineering Caddy to the top of the pile, one tenth faster than Bourdais andwell over half a second faster than the quickest Acura ARX-05 at this stage, the Wayne Taylor Racing machine of Ricky Taylor.
