The Ligier European Series is a European sports car racing endurance series inspired by the 24 Hours of Le Mans race and organized by Ligier Automotive in collaboration with the Automobile Club de l'Ouest (ACO).

[1][2] The Ligier European Series is divided into two classes: JS P4 and JS2 R.[1] Built in 2017, the Ligier JS P4 is the sports prototype car of the championship, designed as a step between the Group CN and LMP3 categories.

The car made its debut in the 2018 British LMP3 Cup and features a carbon fibre composite monocoque and body, as well as LMP3-based brake discs and calipers.

Intended as a revival of the classic Ligier JS2, the car is a mid-engined, 2-door coupé borrowing several design cues from its predecessor.

[6][7][8] Specifications:[6] Both vehicles share the same 3.7-litre, naturally-aspirated Ford Duratec V6 engine coupled with Michelin tyres and a 6-speed Quaife sequential transmission, semi-automatic in the case of the JS P4 and manual for the JS2 R. Upgrade kits for both cars were introduced in 2022.
