After a GTD car choking on pit entry caused the first red flag, the running was interrupted again after only 16 minutes due to debris at Turn 2. At that point, only Philipp Eng in the #24 BMW M Hybrid V8 had set a vaguely representative time, with a 1m39.586s.
When action resumed Tom Blomqvist drove the polesitting Meyer Shank Racing Acura ARX-06 to the top of the times with a 1m35.688s run, a few hundredths ahead of Renger van der Zande’s #01 Chip Ganassi Racing Cadillac V-LMDh, and Albuquerque’s Acura.
