Their respective LMDh prototypes have had their minimum weights reduced by seven kilogrammes for the Bahrain 8 Hours on 4 November under the Hypercar class Balance of Performance.
A change has been made to the so-called ‘platform BoP’, which means the move is an attempt to create a level playing field between the two manufacturers running LMDh machinery and the Le Mans Hypercars from Toyota, Ferrari and Peugeot.
This explains why the weight reduction is the same for both the Porsche and the Cadillac.
New BoP rules for 2023 allowed for a platform change after the Monza and Fuji rounds in July and September respectively.
It follows wholesale revisions for all the cars competing in Hypercar after the Le Mans 24 Hours in June.
This was meant to be the only manufacturer change of the season, but WEC rule makers the FIA and the Automobile Club de l’Ouest opted to override the regulations without the consent of the competitors ahead of Le Mans.
