The LM P2 category is aimed at private teams, independent from manufacturers and/or engine suppliers. It responds to technical regulations and a strict limit on costs, defined by the FIA and the ACO. In 2017, a new regulation comes into place with only four manufacturers chosen for the chassis – Onroak Automotive, Oreca, Dallara and Riley Tech/Multimatic – and a unique engine supplier, Gibson Technology. Meanwhile, the LM P2 of the previous generation are still allowed to run. The continuation of the Ligier story in the LM P2 category will be written from 2017 with the brand new Ligier JS P217, one of the four models meeting the new ACO-FIA regulations. This new sport-prototype of the brand benefits from the experience gained in the category with the Ligier JS P2.
The Automobile Club de l'Ouest (ACO) launched a new sport-prototype category in 2015 – named LM P3. This category makes it easier to access endurance racing as it has fewer budgetary, technical, driving and operational constraints than the LM P2, all the while benefitting from great safety. Six manufacturers were chosen to build the chassis, which is mandatorily closed – Ginetta, Onroak Automotive for the Ligier brand, Adess, Dome, Riley, and Norma – and one unique powertrain made up of the Nissan V8 atmospheric engine with 420 horsepower and an Xtrac gearbox.

It's the category with the easiest access to endurance racing in terms of costs, driving and operations. The CN are not just reserved for circuits. They are also allowed to take part in hill climbs.
