The World Endurance Championship (WEC) and the 24 Hours of Le Mans are on the cusp of a new season, with the Hypercar category continuing to attract manufacturers. However, a subject that was once central to discussions, the Balance of Performance (BoP), is now more discreet. The governing bodies have chosen not to publicly communicate these figures anymore, a decision taken to refocus attention on the very essence of competition.
The world of endurance racing, and particularly the 24 Hours of Le Mans, has always been synonymous with cutting-edge technology and fierce battles. The premier category, Hypercars, is at the heart of this excitement, attracting major manufacturers thanks to technical platforms like LMH and LMDh. However, the success of this category is intrinsically linked to a complex system: the Balance of Performance (BoP). This device, intended to ensure sporting fairness by adjusting the performance of different cars, has over the years become a subject of almost constant debate, sometimes at the expense of sporting interest itself.
BoP: The cornerstone of Hypercar success
Faced with escalating costs and the complexity of BoP debates, the FIA and the Automobile Club de l’Ouest (ACO) have taken steps to calm the situation. Not only does the regulation now prohibit participants from “commenting on or seeking to influence” the BoP, but since the 2026 season, the BoP figures are no longer made public before each event. This is a radical decision aimed at reducing tension and refocusing discussions on pure performance, rather than technical adjustments.
This new approach, while potentially confusing for the most assiduous observers, is firmly defended by the governing bodies. The objective is clear: to reduce the media frenzy around a subject that, in their view, takes up disproportionate space. The BoP, although complex, is seen as an essential tool for the economic viability of the programmes involved, not solely as the determining factor for victory.
Pierre Fillon defends the ‘secrecy’ of BoP

When questioned about this new policy of discretion surrounding the BoP, Pierre Fillon, president of the ACO, defended this strategy with conviction. For him, the time spent discussing this system is excessive and diverts attention from what truly makes motorsport: strategy, driving, and the team’s overall performance. He reminds us that the BoP is primarily a guarantee of cost control for manufacturers, a strong argument for convincing boards of directors to fund ambitious programmes.
“It’s a delicate subject, on which we spend far too much time,” he told Motorsport.com. “You know, this BoP is very likely at the origin of the success and attractiveness for all manufacturers, because it’s a way of controlling costs. For the boards of directors who finance all these programmes, knowing that with a certain budget they can complete the season, compete in the championship, and have a chance to win without constantly being asked for additional budget, makes this BoP extremely important.”
BoP: One factor among many
Beyond its economic role, Pierre Fillon stressed the need to put the actual impact of the BoP on race results into perspective. According to him, this balance represents only a minor part of overall performance, estimated between 20% and 30%. The decisive elements remain team strategy, driving quality, pit stop efficiency, tyre choice, and attention to detail – all human and organisational factors that make the difference on the track.
“Our objective is to balance the cars against each other to give everyone an equal chance of winning,” he recalls. “But in the result of a race, BoP is perhaps 20% or 30%: strategy, driving, tyre choice, pit stop time, attention to detail, leaving nothing to chance to win a race… all of that remains more important.”
This view aims to deconstruct the idea that BoP is a crutch or an excuse for disappointing performances. “So I find that we spend too much time talking about this Balance of Performance, which is sometimes just an excuse when you haven’t won, when that’s not the reality. The reality is that it remains a race, and to win a race, it’s good to have a solid base with the car, but there’s everything else around it.”
Silence: Endurance’s new weapon?
By removing the BoP from the spotlight, the WEC and the 24 Hours of Le Mans hope to regain a welcome sense of calm. The focus is now on the sporting battle, the quality of the programmes involved, and technological innovation, rather than on the technical adjustments that could disrupt the competition. This accepted discretion could well be the key to a more exciting championship, less prone to controversy, where only raw performance dictates the final standings.
- The BoP is an essential tool for cost control and the attractiveness of the Hypercar category.
- WEC governing bodies have chosen not to publicly communicate BoP figures to reduce debate.
- The ACO president believes BoP accounts for only 20% to 30% of a race’s final result.
- Strategy, driving, and organisation are considered more decisive factors for victory.
- This new policy aims to refocus attention on sporting performance and innovation.
