The small 'great' revolution of the ACO for the WEC 2020


The day of Friday, in the 24 Hours of Le Mans has no activity in track for the WEC. This fact gives rise to the usual parade in the town of Le Mans, the act of signature of autographs from the pilots and also to the celebration of some conferences on the part of drivers, teams, manufacturers and the organization itself. In this aspect, the press conference of the ACO has left the first strokes of the technical regulation to be adopted by the WEC in 2020. The arrival of a hybrid system of rapid recharging, and the control of costs by various means are the keys of this new regulation.

The idea of the rules of the WEC 2020 is to bring plug-in hybrids (PHEVS) to the competition and do so in a framework of spending control with a series of guidelines for the development of prototypes or the number of mechanical components to use. It also will control the number of test private, the hours of wind tunnel and the number of employees you have each manufacturer to full-time in the WEC, which however does not affect the 24 Hours of Le Mans. All of these measures claim that Toyota and Porsche are maintained in LMP1, and to facilitate the arrival of Peugeot.

In this way, the technical regulations of the WEC 2020 maintains the settings of two hybrid systems with a maximum recovery of 8 MJ as in the present, although these may be supplemented by a system plug-in hybrid (PHEVS), which contains a system of rapid recharging to fill the battery in the refuelling pit. It is likely to change the first mile after the stop in the pit lane and after passing the target is in mode 100% electric. While biofuels will accommodate, by the time the hydrogen and the fuel cell are in a second plane.


It will seek to reduce costs with the introduction of active aerodynamic. The use of some type of flap, spoiler, DRS or flaps variables allow you to meet with one of the major objectives of this regulation and which involves having a only aero kit and not two as are used from this 2017. Also it will control the aerodynamics of the flat bottom and will simplify the design of the wheel arches and nose of the prototypes. The time of wind tunnel is trimmed from 800 to 600 hours and the number of test private also will be reduced to change the arrival of a test collective.

will Be limited to four engines per season and two transmissions to use during the year. The number of team staff will be reduced from 65 to 50 people, with Le Mans as an exception. it Is very likely that your time to reach a system of ‘jokers’ in order not to influence in a scale of costs in the development of the chassis, engine, hybrid system or body. This ‘cutting’ mass in the development of the LMP1 will be supplemented with a reinforcement of security in the cage of habitability, which will be larger, with adjustable pedals, and greater protections in the area of the legs of the riders.
