The FIA and the Automobile Club de l'Ouest (ACO) said the World Endurance Championship (WEC) will no longer publish detailed Balance of Performance tables from 2026, with exact weight, power and energy allocation figures shared only with teams.
Bruno Famin, who recently joined the ACO, and Marek Nawarecki, FIA circuit sport director, explained the change at a media briefing in Imola to prevent speculation and misinterpretation of WEC technical data. They said BoP is set during homologation and refined by on-track analysis, while results also depend on setup, strategy, driver management and other variables.
Marek Nawarecki said public disclosure of figures — for example a 20kg weight difference — could lead to incorrect interpretations because the public lacks access to homologation parameters and the data the FIA and ACO collect. The ACO and FIA confirmed all cars returned to the wind tunnel for re-homologation ahead of 2026 and said it is not expected to significantly change BoP application.
