The IMSA WeatherTech SportsCar Championship will conclude its 2025 season with the Motul Petit Le Mans at Michelin Raceway Road Atlanta, and the 10-hour race on the 12-turn, 2.54-mile road course in Braselton, Georgia, will determine the champions in all four four categories.
In Grand Touring Prototype, the No. 6 Porsche Penske Motorsport 963 leads its No. 7 963 teammate by 131 points and can clinch the championship with a seventh or better. The No. 24 BMW M Team RLL M Hybrid V8 lurks 145 points behind in third.
The No. 99 AO Racing ORECA LMP2 07 can capture the LMP2 title with a podium finish, leading the No. 22 United Autosports USA by 85 points.
GTD Pro has the tightest title battle with the No. 3 Corvette Racing by Pratt Miller Motorsports Chevrolet Z06 GT3.R ahead of the No. 81 DragonSpeed Ferrari 296 GT3 by 18 points. The car with the best finish likely will win the championship.
