The Ligier JS P2 is a racing car designed and built by French manufacturer Onroak Automotive and named in partnership with French former racing driver Guy Ligier. Designed for the Le Mans Prototype 2 (LMP2) regulations, it is intended as a second option to Onroak's Morgan LMP2 that has been competing since 2012. As well as being the first closed-cockpit car offered by Onroak, it is also the first car they designed entirely in-house. The JS P2 debuted at the 2014 24 Hours of Le Mans, and has been campaigned in the FIA World Endurance Championship, European Le Mans Series, Asian Le Mans Series and United SportsCar Championship.
Onroak initially planned to develop a car for the Le Mans Prototype 1 category but cancelled these plans to concentrate on the LMP2 category. The design was seen by Onroak as marketable in North America where closed-cockpit designs, which were required for all LMP1 cars, were also prominent choices for LMP2s and Daytona Prototypes in the new United SportsCar Championship. The LMP1 design was therefore evolved into an LMP2 design with measures taken to assure the car met the Automobile Club de l'Ouest's (ACO) cost limitations in LMP2. The car was designed to be able to utilize available LMP2 engines: Nissan and Judd's naturally aspirated V8 engines and Honda's turbocharged V6 engine. A high downforce sprint design and a low downforce Le Mans setup are offered for the car.
