25 Years of Partnership Culminate in the Launch of the New SL90-20LW
SADEV is proud to introduce the new SL90-20LW gearbox, the latest evolution of its renowned SL90 transmission platform. Selected by Ligier Automotive for the new Ligier JS2 RS, the gearbox marks a new milestone in a partnership that has been shaping international motorsport for more than 25 years. From Formula 4 single-seaters to GT and endurance racing vehicles, SADEV and Ligier have combined their expertise to deliver reliable and high-performance racing solutions used worldwide.
THE NEW SL90-20LW
The SL90-20LW is built upon its predecessor and benefits from the latest engineering innovations. Using advanced calculation and simulation tools, our design office team has designed the gearbox with a focus on lubrication efficiency and a new casing architecture. The result is a durable and capacitive gearbox, designed for high-performance race cars competing in Circuit, Endurance, Sprint, Hill Climb and Rallying. The new gearbox will be displayed for the first time at PMW Expo 2026, taking place on 11-12 November in Cologne, Germany.
FIRST APPLICATION WITH LIGIER
LIGIER JS2 RS
The Ligier JS2 RS represents a major new milestone in the evolution of Ligier Automotive's GT racing lineup. . Built around a dedicated carbon-fibre monocoque homologated to FIA EII SC regulations and complying with LMP3 crash-test standards, the car is designed for both gentleman drivers and professional racers. Beneath its carbon-fibre bodywork with optimized aerodynamics lies a Ford 3.5L EcoBoost V6 engine producing 650 hp, supported by state-of-the-art electronics including a MoTeC ECU, Bosch ABS, traction control, and a Brembo endurance braking system.
The car is equipped with the latest evolution of the SADEV SL90-20, the SL90-20LW gearbox. Already renowned for its versatility and its ability to handle up to 700 Nm of torque in circuit racing applications, this two-wheel-drive transmission incorporates several major technical enhancements, including a completely redesigned casing, an upgraded lubrication system, optimized gearsets and a revised range of gear ratios. These developments contribute to improved efficiency, enhanced performance and increased reliability. This new gearbox is ideally suited to international endurance championships, offering optimized maintenance intervals and controlled operating costs.

25 YEARS OF PARTNERSHIP
More than 25 years ago, in the early 2000s, the first project between SADEV and Ligier Advanced Technologies (formerly Mygale) was launched through the Formula Renault Campus, a single-seater race car developed for the French young driver championship, now known as the FFSA F4 Championship.
Since then, numerous projects have been developed together, particularly in the early 2010s around single-seater racing cars such as Formula 3 and Formula 4, as well as Sport Prototypes and, more recently, GT cars:
• 2004 – Sport Prototype | LIGIER JS49 – SL75-14
• 2008 – Sport Prototype | LIGIER JS51 – SL75-14
• 2012 – Sport-Prototype | LIGIER JS53 – SLR82-14
• 2014 – Single-seater | LIGIER F4 – SL75-14LW
• 2016 – Single-seater | LIGIER JS F4 – SL75-14LW
• 2018 – Single-seater | LIGIER JS F3 – SL82-12LW
• 2022 – Single-seater | LIGIER JS F422 – SLR75-14
• 2025 – Single-seater | LIGIER JS F326 – SLR82-14
• 2025 – GT | LIGIER JS2 RS – SL90-20LW
Today, these projects continue to make their mark on motorsport worldwide. Ligier race cars equipped with SADEV transmissions compete in numerous championships, including FIA F4 Championships in France, China, India and the United States, as well as the Formula Regional Americas Championship, U.S. F4 Championship, Ultimate Cup Series and the 24H Series.
FOCUSING ON ANOTHER RECENT PROJECT
LIGIER JS F326
Developed by Ligier Advanced Technologies, the Ligier JS F326 is the new single-seater designed to meet the requirements of the FIA Formula Regional Gen2 category. Weighing just 575 kg, the car combines an ultra-safe carbon-fiber monocoque with advanced aerodynamics. It is powered by a 280 hp Horse V20 Performance 2.0L turbocharged engine, featuring an electric “Push-to-Pass” system and compatibility with 100% sustainable fuels.
On the transmission side, the car is equipped with the SADEV SLR82-14 gearbox, capable of handling 400 N.m of torque in single-seater circuit racing applications. It is paired with reinforced gearsets specifically designed for turbocharged powertrains. This advanced mechanical package provides drivers and technical directors with a reliable, lightweight and high-performance solution, ensuring maximum efficiency on track.
