Radical Cup NA is a sprint series for Radical sports prototypes run in multiple classes. The field is competitive amateur to semi-professional, anchored by drivers such as Michai Stephens and Jon Field. It draws drivers from club racing and regional championships including SCCA Majors and NASA, and sits notably stronger than those feeders while comparable in depth to peer series like American Endurance Racing. Drivers move on primarily to IMSA's one-make and endurance cups and to other peer-level racing, making it a mid-tier step for drivers progressing within amateur and early-professional ranks rather than a destination series. The multi-class structure separates graded drivers in the PLATINUM and PRO classes from an ungraded field in GOLD and PRO 1340.
