The Ferrari 499P Le Mans Hypercar will run 5kg heavier and with maximum power reduced by 12kW or 16bhp from the levels at which it won the double-points round of the WEC last month with Antonio Giovinazzi, Alessandro Pier Guidi and James Calado.
Toyota, which finished second and 1m21s in arrears of Ferrari in the 24 Hours, has an unchanged weight for the Monza 6 Hours on 9 July and will run with 5kW or 6.7bhp less maximum power.
Wholescale BoP changes for the remainder of the 2023 WEC season were published on Monday evening.
This one-off, across-the-board change of what is known as the manufacturer BoP was scheduled in the original framework laid down for this season.
WEC rule makers the FIA and the Automobile Club de l’Ouest opted to unilaterally to revise the BoP ahead of Le Mans in what was described as a “correction” of figures published ahead of the season, which were meant to stand until after Le Mans.
Separate BoP tables have been issued by the WEC Committee for each of the three remaining rounds of the 2023 season at Monza, Fuji in September and November’s series finale in Bahrain.
This is because the adjustments made “assign different values to all three of the circuits remaining on the schedule, taking into account the unique characteristics of each of the layouts”, according a statement put out by the FIA.
