The IMSA WeatherTech SportsCar Championship reaches the halfway point of the 2025 season with its first endurance race in three months, racing for six hours with all four categories at Watkins Glen International.
Porsche Penske Motorsport maintains a firm grip on the top two spots of the Grand Touring Prototype championship standings, but Acura won May 31 in Detroit to snap Porsche's four-race winning streak to start the season.
The premier prototype class has featured parity on the 11-turn, 3.4-mile road course in Watkins Glen, New York, where five manufacturers have won in the past four years: Porsche (2024), BMW ('23), Acura ('22), Cadillac ('21) and Mazda ('21).
Watkins Glen will mark the return of the LMP2 division, which last raced March 15 in the Twelve Hours of Sebring (the most recent endurance event on the IMSA schedule).
