Radical Cup NA is a sprint series for Radical sports prototypes run across four driver-ability classes. The field is semi-professional; most drivers are ungraded amateurs, with a small cohort of graded Silver and Bronze sportscar racers integrated across the classes, strongest in the Platinum and Pro 1500 tiers. Top drivers include Michai Stephens and Bobby Thompson. The series draws drivers from SCCA regional and national competitions and sits above those feeder series in calibre, comparable to American Endurance Racing. Drivers typically arrive from club-racing backgrounds and move on to IMSA championships or peer-level GT and touring-car series, functioning as a semi-professional stepping stone for developing track-racing talent.
