Originally called Crawford F4, this F4 single-seater was selected by the FIA to be the exclusive model in the F4 U.S. Championship since 2016. Its carbon fibre chassis combines speed and safety. Equipped with a 2-litre Honda engine pushing out 160 bhp and Hankook tires, it was renamed the Ligier JS F4 from the 2018 season onwards.

F4 Cup Canada will make its debut in 2019.
