Alpine has regained some power in an increase ahead of the 24 Hours of Le Mans test day but its maximum output sits lower than the amount it had for last year’s event.
The Hypercar BoP table for Sunday’s test shows the Alpine A480 Gibson at a maximum value of 420 kW (563 hp), which is 10 kW or about 13 hp more than what it had for the previous FIA World Endurance Championship round at Spa-Francorchamps.
However, compared to last year’s Le Mans, Alpine has 30 kW (40 hp) less power for the 90th edition next weekend.
The French squad was handed a 20 kW power reduction following the opening round of the WEC campaign at Sebring in March, half of which has since been restored.
Toyota Gazoo Racing’s BoP is unchanged since Spa, with the Toyota GR010 Hybrids retaining the 190 km/h hybrid activation speed they have used so far this season.
They will also run to an unchanged maximum power output of 506 kW, a minimum weight of 1070 kg and a maximum stint energy allowance of 898 megajoules.
Last year the Toyota GR010 Hybrids debuted at Le Mans with 515 kW of power available, 4 kg less weight and 64 MJ more energy to expend over the course of a stint.
The Japanese manufacturer was not subject to a minimum hybrid activation speed in 2021, with that part of the BoP introduced to the Hypercar class for the current season.
The pair of Glickenhaus 007 Pipos are set to appear on track at Le Mans under the same BoP settings that the American constructor started its WEC campaign with.
The BoP package for the non-hybrid LMH car consists of a 520 kW power output, a minimum weight of 1030 kg and a maximum stint energy allowance of 910 MJ.
Glickenhaus Racing made its Le Mans debut last year with the same power output and weight levels, but its energy allocation was 55 MJ higher than it is now.
Alpine’s energy amount has also been reduced, while its 952 kg minimum weight is unchanged since both the Belgian WEC round and Le Mans last year.
BoP Figures Set for GTE Categories
The Chevrolet Corvette C8.R and the Ferrari 488 GTE Evo will remain at the 1269 kg they stood at in 2021, while the Porsche 911 RSR-19 has kept its 1285 kg minimum.
Corvette and Ferrari also have the same fuel capacity numbers, although Porsche’s 102-liter tank is slightly larger than the 99 liters it was permitted for last year’s edition.
Ferrari’s turbo boost curve is the same as it was for last month’s TotalEnergies 6 Hours of Spa, which the Italian manufacturer won, however it has higher values compared to the previous Le Mans BoP.
The Corvette’s air restrictor diameter is 0.8 mm smaller than it was last year.
In GTE-Am, the Aston Martin Vantage GTE has gained 5 kg since the 89th running of Le Mans, in the only weight difference across the two GTE classes.
The Aston contingent also holds a 1-liter fuel capacity reduction since last August, while the GTE-Am Porsches have an additional 3 liters, as is the case in GTE-Pro.
Changes to the turbo boost figures exist for both Aston Martin and Ferreri compared to last year.
