Sebastien Bourdais set the best time of 1m46.180s aboard the #01 Cadillac DPi-V.R around 40 minutes into the 90-minute session, around four tenths slower than Pipo Derani's FP2 benchmark.
Following a late red-flag period caused by a Turn 17 shunt for Katherine Legge's Team Hardpoint Porsche 911 GT3 R, Earl Bamber put the sister #02 Ganassi Cadillac in second on a 1m46.546s, moving ahead of Derani in the best of the Action Express Racing-run Caddys, the #31 Whelen Engineering car.
