North America’s premier sportscar series returns to America’s National Park of Speed for a six-hour endurance event, bringing several familiar names for race fans and a handful of down-to-the-wire battles. IMSA races feature elite sportscars 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. With Motul continuing as the title sponsor, the format aligns Road America with endurance classics such as the Rolex 24 at Daytona, Mobil 1 Twelve Hours of Sebring, Sahlen’s Six Hours of The Glen, and Motul Petit Le Mans.
