The 2019 Petit Le Mans (formally known as the 2019 MOTUL Petit Le Mans for sponsorship reasons) was the 22nd running of the Petit Le Mans, and was held on October 12, 2019. It was the last race in the 2019 IMSA WeatherTech Sportscar Championship, and the last race of the 2019 Michelin Endurance Cup, and was run at Road Atlanta in Braselton, Georgia.

Qualifying

Friday's afternoon qualifying session was broken into three sessions that were scheduled for 15 minutes each. Cars in GTD were sent out first before those grouped in GTLM and DPi/LMP2 had two separate identically timed sessions. All cars were required to be driven by one participant and the starting order was determined by the competitor's fastest lap. IMSA then arranged the grid so that the DPi, LMP2, and GTLM cars started in front of the GTD field.

Felipe Nasr in the No. 31 Cadillac set a new track record to clinch pole position with a time of 1 minute and 08.457 seconds.[38] [39] He was joined on the grid's front row by Ricky Taylor's No. 7 Acura who was 0.141 seconds slower. Filipe Albuquerque qualified the No. 5 Cadillac in third, ahead of Dane Cameron's fourth-placed No. 6 Acura.[40] The two Mazdas were fourth and fifth (the No. 77 car driven by Bernhard in front of the No. 55 vehicle of Tincknell). Trummer's No. 84 Cadillac took sixth and van der Zande's No. 10 Cadillac qualified seventh.[41] Pigot's No. 50 Juncos Racing Cadillac took eighth, ahead of Goikhberg in the No. 85 JDC-Miller MotorSports Cadillac and the No. 54 CORE Autosport Nissan driven by Jon Bennett rounded out the DPi qualifiers. In LMP2, Masson set the fastest time in the Performance Tech Motorsports entry, with his fastest lap being 0.131 seconds faster than McMurry in the No. 52 PR1/ Mathiasen Motorsports Oreca.

In GTLM, James Calado in the No. 62 Ferrari set a new category track record to take pole position with a time of 1 minute and 15.639 seconds.[42] García in the No. 3 Corvette set the second fastest time, but would start at the back of the GTLM field after his car failed the post-qualifying technical inspection where it was discovered that the Corvette was found to not have complied with mandated ride height. As a result, Philipp Eng would start in second position followed Vanthoor's No. 912 Porsche in third.

In GTD, Corey Lewis took his second consecutive pole position of the season with a lap of 1 minute and 19.530 seconds. He was joined by Ben Keating's No. 33 Mercedes-AMG on the grid's front row with his best lap being 0.135 second slower, and Jeff Westphal drove the No. 63 Scuderia Corsa Ferrari to third place. Justin Marks qualified the No. 86 Acura fourth, ahead of Christina Nielsen's fifth placed No. 57 Acura. The No. 96 Turner Motorsport BMW failed to record a time due to Robby Foley spinning at turn 10a and beaching the car at the gravel trap on his outlap. The No. 29 Montaplast by Land-Motorsport and No. 47 Precision Performance Motorsports entries lost all their lap times due to both teams crew touching their respective cars.
