For you ALMS, Sport Car LMP fans:

14.1.9 – Temperature inside the cockpit (closed car) :
The ambient temperature around the driver must not be higher than 30°C (86°F) whatever the temperature on the outside when the car is in motion. After a stop, the temperature must go back down to this value in 5 minutes maximum. An efficient air conditioning system comprising a compressor, a condenser, a pressure reducer and an evaporator is compulsory for the closed cars. It must be described on the homologation form and approved by the ACO.
Subsequently the ACO has increased the all-up weight for LMP1/2 by 25 kgs making them 925 and 775 respectively. Presumably this is to take into account the weight increases caused by the fitment of an air conditioning (AC) system. This weight increase is across the board for closed and open-top cars (even though it is a regulation, understandably, for closed top only) in order to maintain parity. To further that, the ACO is allowing a engine restrictor diameter increase for closed top cars (taking into account power loss suffered from running said mandated AC system)
