In 2014, the FIA introduced the Formula 4 concept globally to bridge the gap between karting and open-wheel racing. The Sports Car Club of America created the Formula 4 United States Championship in 2016. The series has experienced rapid growth in popularity due to its affordability and competitiveness.

In 2024, the series transitioned to the new Ligier JS F422 chassis and Ligier Storm power, rendering the previous model obsolete.

The Formula 4 United States Championship is part of a ladder system. The winner of the Driver's Championship will receive a scholarship to compete in the 2025 FR Americas series. Also included is the lease of an engine and Ligier JS F3 chassis from Ligier Automotive. There are also awards for the second and third-place finishers in the title chase. Finally, the series provides cash payouts and prizes at each race.

The series includes an impressive alumni list, including Kyle Kirkwood, David Malukus, Benjamin Peterson, Ernie Francis Jr., and Linus Lundqvist.

The 2026 Formula 4 United States Championship consists of seven weekends, with three races at each venue, except Mid-Ohio Sports Car Course, VIRginia International Raceway and Barber Motorsports Park, which will host two contests.
