The FIA has announced a timeline to address the ongoing controversy surrounding the Mercedes engine “loophole.”

In a press release, the sport’s governing body confirmed that votes have been submitted by the Power Unit Manufacturers, with the outcome expected within the next 10 days.

The sport has recently been dominated by the controversy surrounding the compression ratio of the Mercedes power unit. Respective team principals, including more recently Jonathan Wheatley and Laurent Mekies, have echoed their sentiments on the issue. However, the FIA has now clarified its position on the engine controversy.

FIA clarifies position on engine loophole

In its statement, the FIA highlighted the collaborative effort made to quantify compression ratio changes. The governing body explained that a proposal has been submitted, and a vote by the Power Unit Manufacturers is currently underway, with results expected soon.

“Over recent weeks and months, the FIA and the Power Unit Manufacturers have collaboratively developed a methodology to quantify how the compression ratio changes from ambient to operating conditions. Following validation of this approach, a proposal has been submitted whereby, from 1 August 2026, compliance with the compression ratio limit must be demonstrated not only at ambient conditions, but also at a representative operating temperature of 130°C.”

“The vote has been submitted to the Power Unit Manufacturers, and its outcome is expected within the next 10 days and will be communicated in due course. As with all Formula 1 regulatory changes, any amendment remains subject to final approval by the FIA World Motor Sport Council.”

Earlier, the Williams F1 team principal, James Vowles, expressed confidence in the legality of the Mercedes power unit.

Vowles, in his assessment, highlighted the immense innovation the team undertook to achieve such a feat. The 46-year-old also urged against the FIA banning the Mercedes engine, noting it could dent the boundaries of innovation that have long characterised Formula 1.
