The first bulletin giving the Equivalence of Technology for the LMP1 class at next weekend’s 2020 24 Hours of Le Mans has been published.
As previously confirmed the system of ‘Success handicap’ in the LMP1 class is suspended for Le Mans, the cars instead reverting to the previous system of adjustment pertaining to their differing traction methods.
By comparison with the values in play at the 2019 Le Mans 24 Hours the adjustments made are as follows:
The non-hybrid LMP1s remain at the same weights as in 2019. The normally aspirated Gibson-powered Rebellions and ByKolles at 816 kilos, the turbo AER Ginetta at 833 kilos.
The hybrid-powered Toyotas though gain 7 kilos, up to 895 kg in 2020 from 888 kg last year.
In other areas, there are breaks handed to the non-hybrids. The maximum fuel per stint goes up from 50.8 kilos for the normally aspirated cars to 55.4 this year, a move designed to unlock more of the performance of the cars and to enable equal stint lengths.
The Ginetta too sees an increase, up from 48.4 kilos to 52.8 for the more fuel-efficient AER.
The Toyotas remain at 35.1 kilos per stint, a reflection of the efficiency of their hybrid powertrains.
Fuel Fill Time
Finally, the fuel fill-time advantage of the Toyotas is reeled in too, the fuel rig restrictor diameter is increased for the normally aspirated cars from 22.3mm in 2019 for the Gibson-powered cars to 24.1 mm this year.
The Ginettas see an increase for a turbo-powered car from 21.75 to 23.5 mm.
The Toyotas remain at 19mm.
