Leupen expressed his frustration at both the Balance of Performance changes made to the Hypercar class in the run-up to last weekend’s Test Day, made without the consent of the manufacturers, and the decision to bring back tyre warmers for Le Mans only.
Toyota was the worst-hit of the Hypercar manufacturers by the BoP adjustments, having 37kg of extra weight added to its GR010 HYBRID - something driver and team principal Kamui Kobayashi had estimated would be worth 1.2 seconds a lap around the Circuit de la Sarthe.
