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 estimated would be worth 1.2 seconds per lap at the Circuit de la Sarthe.
While the sporting regulations in the World Endurance Championship do not allow open criticism of BoP decisions, the target of Leupen’s ire was the way the changes were implemented by the FIA and the Automobile Club de l’Ouest.
Speaking prior to Ferrari bagging pole position in Thursday evening’s Hyperpole session, he suggested that some of Toyota’s rivals in the Hypercar class had managed to gain an advantage from the organisers simply by “screaming the loudest”.
“I can’t talk about the weight [itself], but we can talk about the fact they have changed the process and the system in the middle of the game,” Leupen told Autosport.
“We are of the opinion that they should have not done this. And if they had to do this, not in the way they have done it. We would like to have these things not happening again.
“Of course, there is pressure [on the organisers]. Of course, it’s not nice that if you just started a programme you cannot win immediately. But there is some logic to this.
“From our point of view, the logic is not to scream the loudest and get something. The logic is that we have been working hard for a long time, and this is more or less nullified.
“It seems now that if you scream loud enough, something is changed to your advantage. We are very unhappy with this process.”
