US F4 is a single-class sprint series for solo drivers in open-wheel cars. The field is professional to entry-level professional; it draws from club and regional racing below it and feeds drivers upward to USF Pro 2000 and Formula Regional Americas. Cooper Shipman and Alex Popow Jr. lead the current grid. The series sits above the regional feeder ranks, stronger than the Lucas Oil Formula Car Race Series and the SKUSA SuperNationals but weaker than USF Pro 2000; it is comparable to Formula Regional Americas, its peer, and trades drivers readily with both that series and the professional levels above.
