The FIA issued a bulletin during free practice 3 at Fuji announcing further Equivalence of Technology changes to the LMP1 class, effective in qualifying, to further reduce the performance gap between the hybrid and non-hybrid prototypes in the field ahead of tomorrow’s race.
The changes see the maximum fuel allocation per stint and max petrol energy per lap increased for the LMP1 non-hybrid teams. No changes have been made to the Toyota TS050 HYBRID’s EoT parameters in this change.
Rebellion Racing and DragonSpeed — which race with normally aspirated Gibson engines — will run with 55.5kg of fuel per stint, and 75.2 MJ per lap. Before, the teams ran with 54.4 kg of fuel per stint and 73.7 MJ per lap.
The turbocharged LMP1s from ByKolles (NISMO) and SMP Racing (AER) will run with 50.3kg per stint and 69.7 per lap. This is a change from 49.3 kg of fuel per stint and 68.3 MJ per lap.
However, despite the change (the second since the 6 Hours of Silverstone), there is still major discontent among the privateer teams in LMP1, who explained to RACER that the tweak is still not significant enough to allow them to extract the maximum current performance potential of their cars. To ensure they are compliant with the fuel parameters laid out, they will still have to ask their drivers to lift and coast each lap, even with the change this morning.
The changes were made with data collected from the three practice sessions so far this weekend, which all saw Toyota Gazoo Racing’s TS050 HYBRIDs finish 1-2, with times considerably faster than the privateers.
The amendment to the EoT cannot be appealed.
