Motul SportsCar Endurance Grand Prix Featuring IMSA

North America’s premier sports car series returns to America’s National Park of Speed, bringing several familiar names for race fans and a handful of down-to-the-wire battles. IMSA races feature elite sports cars from nearly 20 different manufacturers, including Mercedes, Ferrari, Chevrolet, and Aston Martin. The skill of the drivers, paired with advanced automotive technology, creates a high-stakes, adrenaline-fueled race weekend you do not want to miss. The midsummer WeatherTech Championship race at Road America will evolve into a six-hour endurance event in 2026, with Motul continuing as the title sponsor.
