In 2014, the ACO announced a new category of Le Mans Prototypes, known as LMP3, which would replace the previous Le Mans Prototype Challenge (LMPC) class in 2015. The number of constructors was limited in the class, with licenses being issued to 6 manufacturers, namely ADESS, Ligier (Onroak Automotive), Ave/Riley, Norma, Dome, as well as Ginetta. Nissan was later announced to be supplying the spec engine, the VK50VE producing 420 hp. The car was launched on 2 February 2015.
