McLaren CEO Zak Brown sent a formal letter to FIA President Mohammed Ben Sulayem calling for immediate rule changes to prevent common ownership across multiple Formula 1 teams, three people familiar with the correspondence confirmed. The letter arrived at FIA headquarters in Geneva within 72 hours of reports that Mercedes parent Daimler is exploring a minority stake in Alpine, the Renault-owned constructor currently valued at roughly $900M enterprise.
Brown's intervention targets Article 7.3 of the FIA Sporting Regulations, which permits shared ownership provided teams maintain "operational independence." The McLaren executive argues the language creates compliance grey zones that disadvantage single-team ownership structures, particularly around wind-tunnel allocation, CFD development hours, and constructor prize-money distribution. Mercedes currently holds a 33% stake in McLaren Group through a £450M investment completed in 2022, but that position sits below the chassis manufacturer layer and carries no technical governance rights. A direct Alpine stake would place Mercedes in simultaneous constructor and shareholder roles across 20% of the grid.
The timing matters because FIA governance windows close March 31 for regulation amendments affecting the current Concorde cycle, which runs through 2025. Any ownership structure approved before that deadline becomes grandfathered under existing language, creating a 24-month window where Mercedes could theoretically steer technical resources across two teams while competitors operate under stricter separation protocols. Brown's letter specifically references the 2023 cost-cap breach penalties, where Red Bull's $432,000 overspend triggered wind-tunnel time reductions. Under multi-team scenarios, those penalties lose deterrent value if a parent company can reallocate aero development across sister operations.
The commercial stakes extend beyond competitive balance. Liberty Media's $17B acquisition of Formula 1 in 2017 hinged on franchise-style team valuations, where each constructor operates as a standalone asset with independent revenue streams and equity structures. Dorilton Capital paid $200M for Williams in 2020; that same team fielded offers above $800M in 2024 preliminary talks. Cross-ownership compresses those valuations by introducing execution risk around FIA enforcement and future rule interpretations. Family offices sizing paddock entries now face structural uncertainty that didn't exist 18 months ago when Andretti's $1B+ bid collapsed over grid dilution concerns.
Mercedes team principal Toto Wolff, who holds a 33% stake in the Silver Arrows operation, declined comment through a Stuttgart spokesman. Alpine CEO Laurent Rossi told French media the Renault board is "evaluating all partnership structures that preserve operational sovereignty," which team insiders translate as keeping Viry-Châtillon engine development separate from any Brixworth collaboration. The FIA issued a two-sentence statement acknowledging receipt of Brown's letter and confirming "ongoing governance review of ownership frameworks."
What happens next depends on whether Ben Sulayem convenes an extraordinary World Motor Sport Council session before the March deadline or lets the Alpine-Mercedes structure play out under current rules. Brown's letter reportedly includes 14 pages of appendices detailing historical precedents, including the 2008 Super Aguri collapse after Honda withdrew technical support mid-season. The McLaren executive also chairs the Formula 1 Commission, giving him procedural leverage to force a grid-wide vote if the FIA declines unilateral action.
Watch for three developments by mid-March: whether Mercedes files formal notification of an Alpine stake purchase, triggering FIA technical governance review; whether Brown escalates to a public campaign through F1 Commission channels, likely during pre-season testing at Bahrain; and whether rival teams—particularly Red Bull and Ferrari, who've remained silent—file supporting letters. The FIA's compliance department already requested Q4 2024 financial audits from all 10 teams under the cost-cap protocols, suggesting governance scrutiny was escalating independent of Brown's intervention.
The franchise model Liberty sold to Wall Street assumes 10 independent operators splitting $1.2B annual prize money. That math breaks if 2-3 teams operate under shared capital structures, particularly when engine customers negotiate technical partnerships that blur constructor definitions. Brown's letter doesn't name Mercedes, but the 2022 McLaren investment already created the template for what he's now arguing against. The difference is who controls the wind tunnel.
The takeaway
Brown's March 31 deadline forces FIA to either ban cross-ownership or grandfather Mercedes-Alpine structure for two Concorde cycles.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
