Opinion: Why WEC’s BoP secrecy stance is set to backfire

Previously, Motorsport.com's objective analysis of power-to-weight ratios provided a mathematical anchor for fans.

The necessity of such oversight is evidenced by recent events in IMSA, which, despite promises of a tight performance window, saw the delta in power-to-weight ratios grew to a maximum of 0.311kg/kW within just two races.

In the future, WEC will see this factual basis replaced by the very speculation it seeks to avoid. Since journalists can no longer verify performance, every team will be able to blame a poor result on the BoP without fear of contradiction.

The previous obligation for teams to provide honest answers disappears along with the media’s role as a watchdog. The result is the Streisand Effect: the debate will not be silenced; it will simply become more subjective and more widespread due to the lack of facts.

Ferrari’s WEC boss Antonello Coletta is already ringing the alarm: "It is clear that we all want to know more about the background of the competition. Unfortunately, this is an aspect that will be missing from the narrative of the race."

How will it affect Le Mans?

The implications of this shift go significantly further. Bruno Famin admitted that the organisers are not yet ready to commit to a specific BoP process for Le Mans.

Without public oversight, the FIA and ACO will have greater discretion in how BoP is applied and communicated internally with manufacturers and teams.

Past instances could at least be analysed after the race, such as the 2016 Le Mans 24 Hours, when only Ford and Ferrari were able to fight for the LMGTE Pro victory for the 50th anniversary of their legendary rivalry. Another example is the 2023 weight penalty imposed on Toyota against the WEC's own established regulations.

In the future, this level of scrutiny will be impossible.

There is also a risk that the world’s greatest race could be shaped by decisions that cannot be externally verified. In the absence of transparency, even far-fetched scenarios, such as an auction for the best BoP, cannot be dismissed outright.

Transparency is the insurance policy for fair competition. By canceling this policy for 2026, FIA and ACO are stripping the WEC of its status as a verifiable technical contest. What remains is a closed system where results are finalised in back rooms rather than on the track.
