Start Climbing the Open-Wheel Ladder

Welcome to the Ligier JS F4 Series—designed to help young karters transition to racecars and to prepare them for competition in the FIA-certified Formula 4 United States Championship, Formula Regional Americas Championship and beyond. With F4 U.S. and FR Americas devised as the initial steps on the Road to F1, the newly-rebranded Ligier JS F4 Series will strengthen the current ladder system while providing another avenue for drivers to race single-seater cars. Utilizing the first generation Ligier JS F416 chassis, Hankook racing tires and Honda engines serviced by Mountune USA, the Ligier JS F4 Series is available to drivers ages 14 years and older.

The Ligier JS F4 Series offers its champion an opportunity to advance their career by awarding a scholarship to compete in F4 U.S. the following season. With the use of a JS F422 chassis and engine from Ligier, two sets of tires per event from Hankook and race entry fees from Parella Motorsports Holdings (PMH), the prize is valued at $133,600.
