International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2018 IMSA SportsCar Championship (IMSA SCC) in August 2017.[2] It was the fifth consecutive year the event was held as part of the WeatherTech SportsCar Championship and the 21st annual running of the race. The race was the final of 2018's twelve scheduled IMSA automobile endurance races, and the last of four Tequila Patron North American Endurance Cup (NAEC) events.[3] The race was held at the twelve-turn, 2.540-mile (4.088 km) Road Atlanta in Braselton, Georgia, on October 15, 2018.[3] The 2018 Petit Le Mans marked the first IMSA race after the passing of American Le Mans Series founder Don Panoz on 11 September 2018.[4] The DeltaWing and Panoz Esperante GTR-1 did 1 demonstration lap before the race start on Saturday in tribute of Panoz.[5]

Due to a highly controversial change made by the FIA/ACO in the 2018-19 FIA World Endurance Championship, which saw the date of the 6 Hours of Fuji moved to allow Fernando Alonso to compete at the home race of the sole LMP1 manufacturer, Toyota, several drivers which were due to compete in both events were unable to do so.[12][13] As such, the entry list featured a large number of changes compared to the previous rounds of the championship.[14] A total of 37 cars took part in the event split across 3 classes. 14 cars were entered in P, 9 in GTLM, and 14 in GTD.[15] In P, Tristan Vautier substituted for João Barbosa, who received injuries from an accident at the previous round in Laguna Seca.[16] Marino Franchitti substituted for Harry Tincknell in the #55 Mazda Team Joest entry due to a clash with the WEC race at Fuji while Lucas Di Grassi substituted for René Rast in the #77 Mazda Team Joest entry due to a clash with the DTM race at Hockenheimring.[17] Timo Bernhard and Norman Nato subbed for Oliver Pla and Nicolas Lapierre in the Tequila Patrón ESM entries due to a clash with the WEC race at Fuji.[18][19] Gabby Chaves joined Felipe Nasr and Eric Curran in the #31 Whelen Engineering Racing entry.[20] in GTLM, Risi Competizione made its first appearance since Sebring.[21] Chaz Mostert made his IMSA SportsCar Championship debut joining John Edwards and Jesse Krohn in the #24 BMW Team RLL entry.[22] Mathieu Jaminet joined Earl Bamber and Laurens Vanthoor in the #912 Porsche GT Team entry.[23] Bill Auberlen returned to the #25 BMW Team RLL entry.
