The Ligier JS P320 represents an LMP3 Le Mans Prototype crafted by Onroak Automotive in collaboration with former French racing driver Guy Ligier. Engineered to comply with the ACO Generation II LMP3 specifications, this model can be manufactured as an update kit for the earlier Ligier JS P3. Officially introduced on 4 June 2019, it was the inaugural Gen II LMP3 vehicle and is approved for participation in prominent international series such as the Michelin Le Mans Cup, Prototype Cup Germany, Asian Le Mans Series, European Le Mans Series, IMSA Prototype Challenge, and IMSA SportsCar Championship.
Developmental history
The Automobile Club de l'Ouest announced the 2020 Generation 2 LMP3 regulations on 23 May 2018, authorizing homologation for chassis from four manufacturers: Onroak Automotive (Ligier), Duqueine Automotive (Norma), ADESS AG, and Ginetta. These Generation 2 rules were finalized by the ACO on 7 February 2019, with full adoption planned by 2021 and competitive use spanning from 2020 through 2024.
The predecessor, Ligier JS P3, was developed before LMP3 vehicles were expected to compete at the Circuit de la Sarthe, resulting in less aerodynamic refinement and lower maximum speeds compared to rivals such as the Norma M30. To enhance aerodynamic performance across various tracks, Ligier Automotive partnered with Exa Corporation during development.
Approximately 95% of the bodywork on the JS P320 is newly designed, complemented by Öhlins suspension components and an updated cooling system. The car also integrates traction control in accordance with updated regulations. Safety improvements involve redesigned headrests and seats along with Zylon-reinforced side panels. Powertrain upgrades include the introduction of the more robust Nissan VK56 engine, delivering an extra 35 hp.
Prior to its official launch, the vehicle underwent initial testing at Circuit de Nevers Magny-Cours. Its competitive debut took place at Circuit Paul Ricard during the opening rounds of both the 2020 Le Mans Cup and the 2020 European Le Mans Series. Notably, eight out of twelve LMP3 entries were Ligier JS P320s, reflecting significant acceptance within the market.
