The Ligier JS2 R is a GT race car developed by the French manufacturer Ligier, crafted solely for circuit competition. It honors the legacy of the original 1972 Ligier JS2, celebrated for its exceptional handling and outstanding power-to-weight ratio.
Model details
Revealed at the 2018 Paris Motor Show coinciding with Ligier's 50th anniversary, the JS2 R takes strong inspiration from the design and performance lineage of the classic JS2, which notably secured second place in its class at the 1975 24 Hours of Le Mans. The letter "R" signifies "Revival" or "Race". No variant intended for public roads has been announced.
Specifications
The JS2 R is equipped with a 3.7 L Ford Duratec 37 V6 engine, also used in the Ligier JS P4, mated to a 6-speed sequential manual transmission operated via pneumatic paddle shifters. Initially rated at , its output was elevated to by 2020. The braking system features Brembo components, including 6-piston calipers on front rotors and 4-piston calipers on rear rotors. Its suspension setup consists of double wishbones with rear push-rod activation, complemented by adjustable anti-roll bars and dampers. The cockpit prioritizes driver ergonomics, accommodating taller individuals and incorporating a heated windshield.
Designed to minimize operating expenses and simplify upkeep, the JS2 R meets FIA Group E homologation standards. Prospective customers had opportunities to participate in test sessions during November 2018.
Racing involvement
Since its debut in 2020, the JS2 R has been actively competing within its dedicated class in the "Ligier European Series" racing event.
