The Ligier JS P3 is the latest car from French manufacturer, Onroak Automotive. It takes full advantage of its relationship to the Ligier JS P2, in particular in terms of its design and aerodynamics.

Driver comfort was at the heart of the development of the Ligier JS P3. It has a large cockpit that provides plenty of room around the driver’s chest and legs, and its adjustable pedal box in three different positions means that it can accommodate small drivers as well as bigger people. Particular attention has been paid to the ventilation system for the cockpit and the driver.

The use of a protective system for the driver’s head that complies with the future LMP1 regulations is an additional benefit in terms of safety. The Onroak engineers have also paid particular attention to making the LMP3 easy to run and has cost capped the components respecting the philosophy of accessibility to the LMP3 category.
