[4] On 23 May 2018, the Automobile Club de I'Ouest announced a brief outline for the 2020 Generation 2 Le Mans Prototype 3 (LMP3) regulations, alongside chassis models from four manufacturers – Onroak Automotive (Ligier), Duqueine Automotive (Norma), ADESS AG and Ginetta being announced as granted homologation for the new ruleset.

[5] On 7 February 2019, the ACO announced the new 2nd Generation Le Mans Prototype 3 (LMP3) regulations, with full implementation due by 2021, and to be raced from 2020 to 2024.

As a result, the design department of Ligier Automotive collaborated with Exa Corporation to optimise the car's aerodynamics to make it efficient on all circuits.

With the new Generation 2 Regulations traction control could be added, and some safety-related changes were made to the driver's headrest and seat, along with Zylon side panels.
