2024 Ligier JS F4 Series

The 2024 Ligier JS F4 Series is the inaugural season of the Ligier JS F4 Series. The series was founded from the ashes of the Formula Development series, which served as a feeder into the United States Formula 4 Championship, but suffered chronically low grid numbers. The series is sanctioned by Parella Motorsports Holdings.

The series was created for teams and drivers to utilize the first-generation Ligier JS F4 chassis with Honda engines that lost their homologation after the 2023 season as a development series when the United States Formula 4 Championship switched to the new generation Ligier JS F422 chassis with Ligier Storm engines that complied with newer Formula 4 regulations. It serves as a development series for drivers before advancing to the current generation F4.
