The 2018 edition of the 24 Hours of Le Mans was the framework chosen by the Western Automobile Club, promoter of this race and World Endurance (WEC), and the International Automobile Federation to publicize the technical regulation that will come into effect from 2020 and that will serve to say goodbye to the class LMP1 and receive hyper sports. The goal of the change, as announced, is "To recover the appearance, style and lines of the cars of the first category".
Will remain hybrid systems and there will be free choice of the type of combustion engine, although with a power limit of 707 horses. To match performance between different vehicles, a consumption system by performance.
The cars may have a KERS that can deliver up to a maximum of 272 CV and that it will be mounted on the front axle, although it will act on all four wheels to maintain the concept of energy efficiency promoted by the FIA. Likewise, it was confirmed that all cars will have an engine control unit (ECU) common to all.
Regarding aerodynamics, "Polished lines will be sought and mobile devices will be allowed, as long as they are relevant to the automotive industry." While the weight of the machines will be 980 kilos, much more than the current LMP1 (875 kg for the Toyota TS050 HYBRID and 833 kg for the rest of the non-hybrids). With all these specifications, vehicles will be about five seconds slower than today.
Some of the brands that participated in the creation of this regulation were Toyota, McLaren, Aston Martin, Ferrari y Ford, so it is estimated that all will be involved.
