Mustang Challenge North America, the IMSA-sanctioned championship featuring the Ford Mustang Dark Horse R, has revealed its 2026 schedule.

The two-class series will run a 12-race schedule opening in March at Sebring International Raceway, Sebring, Florida, and concluding in September at the Circuit of The Americas (COTA), Austin, Texas.

In total, the series will visit six facilities during the season, including Sebring and COTA, as well as stops at WeatherTech Raceway Laguna Seca, Salinas, California; Mid-Ohio Sports Car Course, Lexington, Ohio; Watkins Glen International, Watkins Glen, New York; and VIRginia International Raceway, Alton, Virginia.

Mustang Challenge North America is open to drivers who hold up to an FIA silver rating and features two classes--Dark Horse and Dark Horse Legends. All drivers can compete in the Dark Horse class, while the Legends class is an optional categorization for any bronze-level driver who is 45 years old and older. Each Mustang Challenge race weekend features two 30-minute practice sessions, one 15-minute qualifying session, and two 45-minute sprint races. Each driver competes behind the wheel of a Mustang Dark Horse R, a car similar to the production Mustang Dark Horse but with minor modifications to make it race-ready.
