Development

The Liger JS P217 was conceived in 2016 in preparation for the FIA and ACO's new regulation changes in 2017. Onroak Automotive built a brand new chassis from scratch and focused on improving the mechanics of the car from the Ligier JS P2. Onroak and technical partners focused on the air cooling of the engine radiators and brakes and cockpit air conditioning. The mechanical features of the car that were concentrated on was the implementation of a new axle, nut, and rim to lessen the time of tire changes, the efficiency of the axles, weight distribution, accessibility of mechanics at the front of the cockpit, aerodynamic efficiency, LMP1 style power steering, and a limited number of chassis pieces. The driver's comfort, space, controls accessibility, and visibility also was paid attention to as well.[1]

The car was unveiled at Spa-Francorchamps publicly in September 2016. It also performed tests at Magny-Cours in September 2016 and Daytona International Speedway in November 2016 for preparation for the 24 Hours of Daytona.[3]

A variation of the prototype, the Nissan Onroak DPi, was created for the IMSA's WeatherTech SportsCar Championship Prototype class under the DPi regulations. The car was developed in partnership with Nissan and Nismo. The powerplant of the vehicle is a 3.8 litre V6 twin-turbo engine from the Nissan GT-R GT3. Other alterations from the P217 include a large front panel and revised side panels.[4] Onroak Automotive will supply Tequila Patrón ESM with two prototypes for the WeatherTech SportsCar Championship.[2]
