The IMSA VP Racing Sportscar Challenge retained LMP3 class cars from the Prototype Challenge series, but introduced GT4 cars to allow for multi-class racing.[2] Beginning in 2025, the series introduced a third class, GTDX, open to GT3-specification cars.[3] The series features two 45-minute races per event weekend with no mid-race pit stops or driver changes.[4] The series is designed as a development series for other IMSA series, and as such drivers must have either a silver or bronze categorization from the FIA to participate.[5]
The series is currently sponsored by VP Racing Fuels.
