IMSA's president Scott Atherton confirmed Petit Le Mans was part of the series' schedule for the 2017 WeatherTech SportsCar Championship at Road America's victory lane in August 2016.[1] It was the fourth consecutive year the event was held as part of the WeatherTech SportsCar Championship and the 20th annual running of the race.[2] The race was the final of 2017's twelve scheduled IMSA automobile endurance races, and the last of four North American Endurance Cup (NAEC) events.[3] It was held at the 12-turn, 2.540-mile (4.088 km) Road Atlanta in Braselton, Georgia on October 7, 2017. Event creator, Don Panoz served as the grand marshal for the 2017 event.[4]
As the final race of the 2017 season, the race marked the swansong for the PC class. First introduced in 2010, the category ran for eight seasons before a lack of interest lead to IMSA ending the class after the 2017 season.[5][6]
The BMW M6 GTLM also entered it its final IMSA event, ahead of the switch to new-generation GTE machinery for BMW in 2018.[7] BMW would introduce the M8 GTE as it was based on the upcoming G15 8 Series.[8]
This would be the final race for entry for Alex Job Racing as the team would step back from professional racing and focus on their historic restorations.[9]
Stevenson Motorsports also entered their final race after announcing they would shut down operations following the event.[10]
There were four practice sessions preceding the start of the race on Saturday, three on Thursday and one on Friday. The first two one-hour sessions were on Thursday morning and afternoon. The third held later that evening ran for 90 minutes; the fourth on Friday morning lasted an hour.[22]
In Friday afternoon's 90-minute four-group qualifying, each category had separate 15-minute sessions. Regulations stipulated that teams nominate one qualifying driver, with the fastest laps determining each class' starting order. IMSA arranged the grid to put Prototypes ahead of the PC, GTLM and GTD cars.[41][22]
The third session of qualifying was for cars in the PC class. James French set the fastest time driving the #38 Performance Tech Motorsports entry.[42]
Pole positions in each class are indicated in bold and by ‡. All Prototype and Prototype Challenge cars were grouped together on the starting grid, regardless of qualifying position.
