Inspired by the Ligier JS2 from the 1970s, the hydrogen-powered JS2 RH2 and the Ligier JS2 R, Ligier Automotive has announced its JS2 RS, a sharper, more performance-focused GT built for endurance racing. The company has also continued to develop the Ligier JS2 R with technical upgrades aimed at delivering greater reliability, performance and durability.
Features from the JS2 R
The Ligier JS2 RS preserves the key features of the JS2 R, including controlled running costs, enhanced safety, extended service intervals and true two-seat configuration.
“With the Ligier JS2 RS, we wanted to take performance further while keeping what made the JS2 R successful: an affordable, reliable and fun car to drive for all enthusiasts, especially gentleman drivers,” said Jacques Nicolet, president of Ligier Automotive.
Spec sheet: JS2 RS
The Ligier JS2 RS features a specific carbon monocoque chassis, FIA EII SC homologated and compliant with the 2025 LMP3 static tests. It’s fitted with a homologated roll cage and Zylon side protection panels. Additional components include a front crash box, hydraulic power steering and a Brembo steel braking system built for 24-hour races. On the electronics side, the JS2 RS is equipped with a MoTeC ECU, Bosch ABS and traction control.
The 3.5-liter Ford V6 Ecoboost engine delivers up to 650bph and is paired with a Sadev SL 90-20 EVO gearbox. A sharp aerodynamic package wraps the car in a carbon splitter with underfloor and rear diffuser.
“The Ligier JS2 RS embodies our vision of a modern GT – a fusion of technology, safety and performance, all while keeping the racing spirit that’s driven Ligier for over 50 years,” added Nicolet.
The company says the JS2 RS is designed for drivers, featuring a carbon monocoque chassis, strong performance and driver-focused safety. The car is eligible across numerous racing series.
Latest upgrades
Ligier says it remains committed to the Ligier JS2 R. Upgrades have been introduced to meet current and future customer expectations, including a new braking system with racing calipers, reinforced pivots and improved gearbox lubrication for the 3MO transmission to enhance durability.
In parallel, the 3.7-liter Ford V6 engine, discontinued in 2023, has been replaced by the 3.5-liter Ford V6, now fitted on all new Ligier JS2 R models. This change will be optional for the 2026 and 2027 seasons in Ligier championships, but mandatory starting in 2028, or earlier in the event of engine failure.
An optional ‘endurance’ version of the Sadev gearbox is also available. Designed to handle high power outputs in long-distance races, it is not mandatory in Ligier championships. Where different engines (3.5/3.7-liter) and gearbox combinations coexist, a balance of performance (BoP) will be applied to ensure fair competition.
