History
editThe car was first unveiled in 2017, at the 2017 24 Hours of Le Mans. It was homologated in the FIA Free Formula cars (Group E) category, and sits between the Group CN and LMP3 performance window.[2] The car made its debut in the 2018 British LMP3 Cup in its own P4 class.[3] The car is primarily used in the Ligier European series.[4] In 2022 the car received an update kit to improve the engine and the brakes. The engine power was increased from 330 hp to 385 hp. These upgrades were mandatory for all teams competing in the Ligier European Series.[5]
