FIA president Mohammed Ben Sulayem told reporters this week the governing body could amend its sporting regulations to prevent Mercedes from acquiring a minority stake in Alpine F1 Team, citing concerns over manufacturers owning pieces of multiple grid entries. The timing is exact: Mercedes has been conducting due diligence on a 10-15% stake in Alpine's parent racing entity since late January, according to three people familiar with the talks.

The proposed structure would give Mercedes a balance-sheet toehold in Alpine while maintaining operational independence for both teams. Renault Group, Alpine's owner, has been shopping minority positions since October as it weighs whether to remain an engine supplier or exit Formula 1 entirely by 2026. The Mercedes talks gained momentum after Flavio Briatore returned as Alpine executive advisor in December and began cataloging which assets—Enstone factory, Viry engine facility, driver academy—could be parceled or sold. One person close to the Renault board said the company views a Mercedes stake as validation, not dilution, assuming the FIA permits it.

Ben Sulayem's comments follow a private letter from McLaren CEO Zak Brown calling for tighter ownership rules. Brown's letter, sent to the FIA president in mid-February, argues that allowing one manufacturer to hold equity in a rival team creates competitive distortions, particularly around engine supply negotiations and technical partnerships. Brown did not name Mercedes or Alpine explicitly, but two paddock sources said the letter was drafted after McLaren learned of the Mercedes-Alpine discussions during a sponsor dinner in Miami. Brown's concern is structural: if Mercedes owns part of Alpine and supplies engines to McLaren and Williams, does Stuttgart prioritize its own team, its equity partner, or its paying customers when allocating development resources?

The regulatory pathway is narrow but navigable. Current FIA rules do not explicitly ban multi-team ownership, but they grant the World Motor Sport Council authority to reject any ownership structure deemed contrary to the sport's integrity. The last time the FIA invoked this clause was in 2016, when it blocked a proposed merger between Haas and Marussia on the grounds that it would reduce grid size. Ben Sulayem's public hint is a signal he would bring the Mercedes-Alpine deal to a council vote if it proceeds. That vote requires a two-thirds majority of the 12-member council, and at least four members are known to oppose multi-team ownership on principle, according to one council member who requested anonymity.

Mercedes has not commented publicly, but team principal Toto Wolff addressed the issue obliquely in a February press briefing, saying his organization evaluates "strategic opportunities across the motorsport ecosystem" and expects "regulatory clarity before committing capital." Translation: Mercedes wants the FIA to rule before it wires money. Alpine has been similarly opaque. Briatore told French media that Alpine is "open to partnerships that strengthen our competitiveness," but declined to confirm active negotiations. Renault Group's quarterly earnings call is March 14, and analysts expect CFO Thierry Piéton to address the Formula 1 investment posture then.

The deal's collapse would leave Renault with fewer options. The company has already spent €450 million on its Viry engine program since 2022 and faces another €200 million in development costs to meet 2026 power unit regulations. A minority investor—whether Mercedes or another party—would offset some of that burden and buy Renault time to decide whether to stay or sell outright. Without outside capital, Renault's board is likely to force a full exit by mid-2026, when the current Concorde Agreement permits teams to withdraw without penalty. One Paris-based fund manager who owns Renault shares said the board views Formula 1 as a "marketing expense with deteriorating returns," particularly after Alpine finished sixth in the constructors' championship in 2024 and lost €80 million operationally.

Brown's letter has split team principals. Red Bull's Christian Horner called multi-team ownership "a non-issue" and said the FIA should focus on cost-cap enforcement rather than "inventing problems." Aston Martin's Mike Krack declined to comment but is known to favor open ownership structures, given that his team's largest shareholder, Lawrence Stroll, also owns 20% of Aston Martin Lagonda. Ferrari's Frédéric Vasseur has privately told colleagues he supports Brown's position, viewing manufacturer equity stakes in rival teams as a precursor to consolidation that could reduce Ferrari's negotiating leverage in future Concorde discussions.

Watch for three events: Renault's March 14 earnings call for any Alpine commitment language; the FIA World Motor Sport Council's next quarterly meeting in mid-April, where Ben Sulayem could table a formal ownership rule; and whether Mercedes accelerates talks with Williams, whose current owners, Dorilton Capital, have entertained minority stake offers from at least two manufacturers since January. If the FIA blocks Mercedes-Alpine, Stuttgart's capital will find another grid slot within 90 days.

The math is simple. Mercedes has $3.2 billion in annual motorsport budget and needs a second data stream as F1's technical regulations converge. Alpine needs €200 million and a decision. The FIA has a rule that does not yet exist but could by April. Someone's phone will ring the day after the council votes.
