The concepts may be different but technologies are equivalent so competitors are on a level playing field. Values were calculated last year and remain the same until after the 24 Hours.
The rules cater for private teams that do not necessarily have the human and financial means to develop complex energy recovery systems. The category is also open to cars without such systems.

Last year, the LM P1 category, which is for closed cockpits only, was split into two groups, LM-P1-L and LM-P1-H. This year, there will be a single group: LM P1. For the first time since 2011, 14 cars have been selected in the category.
To keep cost to a minimum, the tyre allocation (excluding rain tyres) is 7 sets (two front and two back) for the practice sessions, qualifications and warm-up and 12 sets for the race, plus an extra four tyres for the duration of the competition.

In the same way, the number of engines is limited to 5 for all hybrid prototypes for the whole FIA WEC season (7 for newcomers such as Nissan). Other invitees for the Le Mans 24 Hours, that is the third Audi, Porsche and Nissan cars have 2 engines plus one “joker”.

Minimum weight (excluding driver and fuel):
