Porsche has opted to expand its assault on the 2015 Le Mans 24 Hours to three LMP1 cars.
The German manufacturer announced the decision after the expanded assault on the blue-riband World Endurance Championship event next June was given board approval.
The additional car will also be fielded alongside the in-house Porsche squad's two full-season WEC entries at the Spa round at the start of May by way of preparation.
No drivers have been announced for the car, but Porsche LMP1 boss Fritz Enzinger has revealed that three of the five drivers from its GT roster who tested the 919 over two tests in September and October will be given a second try-out in the P1 car early next month at an undisclosed venue.
Enzinger refused to deny that Frederic Makowiecki, Nick Tandy and Michael Christensen were the three who were being invited back for a second run.
Porsche has insisted that its pool of GT drivers will be the starting point in the selection process for the seats in the third LMP1.
It is unclear whether all three seats could go to internal candidates, but Enzinger has admitted to contact with multiple drivers.
Porsche has already retained all six of its regular P1 drivers for next season.
