US F4 is a single-class sprint racing series that runs open-wheel single-seaters. The field is entry-level professional, drawing its strongest contingent from the lower domestic karting and club racing ranks and feeding drivers upward into Formula Regional Americas and USF Pro 2000. Cooper Shipman and Alex Popow Jr. lead the current grid. The series sits above its main feeder series in driver calibre and stands notably stronger than the lower SCCA Majors level, though it remains weaker than USF Pro 2000, the primary destination for its graduates.
