It was inspired by the Ligier JS2 introduced in 1972, a car described as having superior driving dynamics and the best power-to-weight ratio of the time.

The car is powered by the same 3.7 L Ford Duratec 37 V6 engine used in the JS P4, coupled to a 6-speed sequential manual transmission with pneumatic shift mechanism and paddle shifters.

The suspension is a double wishbone system with actuated push-rods at the rear, with adjustable anti-roll bars and dampers.

[7] The JS2 R provided the basis for development of a demonstration hydrogen powered vehicle to be unveiled at the 24 Hours of Le Mans in early June 2023.

The car, called the JS2 RH2, is a joint project of Bosch, who has oversight of the overall vehicle concept including engine, hydrogen storage, and development of a safety concept, and Ligier, who is responsible for vehicle architecture, H2 system integration and cooling.
