Wolff Warns Against 'Full Handbrake' on Customer Teams in Dual-Ownership Row

Mercedes boss Toto Wolff has pushed back against McLaren CEO Zak Brown's demands to outlaw dual-ownership structures in Formula 1, warning against applying a 'full handbrake' on customer teams. While acknowledging concerns over collusion, Wolff argues that forcing every squad to become a full constructor would threaten smaller entries like Haas and undermine grid diversity.

Why it matters:

The dispute challenges the foundation of F1's team ecosystem. Brown has long targeted the Red Bull GmbH model, which controls both Red Bull Racing and Racing Bulls, arguing it distorts fair competition. Wolff counters that customer partnerships remain a lifeline for independent teams, and that an outright ban risks shrinking the grid rather than leveling it.

The details:

• Brown recently urged FIA President Mohammed Ben Sulayem to crack down on dual ownership, citing Laurent Mekies's immediate July 2025 transfer from Racing Bulls to Red Bull Racing. Despite his seniority, Mekies served no gardening leave after Christian Horner's exit and was on the Belgian GP pit wall without delay.
• Wolff defended the customer model by pointing to Haas, noting the American entry only joined F1 through a Ferrari supply deal covering engines, gearboxes, and hydraulics. Before the cost cap, he said, such arrangements were the only realistic path for small teams.
• Gray areas: Wolff admitted shared ownership creates natural advantages, referencing a Miami Grand Prix overtake he suggested may have been facilitated between linked squads. He conceded Brown raises valid questions about personnel transfers and shared resources.
• However, Wolff insisted a total ban is unrealistic today. He questioned how a team like Haas could afford to develop its own engine, gearbox, and rear end while remaining competitive under the cost cap.
• UEFA precedent: Brown has pointed to football's stricter stance, where Crystal Palace was demoted from the 2025/26 Europa League due to owner John Textor's ties to Lyon. F1 currently has no equivalent ownership firewall.

Between the lines:

Wolff is essentially proposing a regulated truce rather than a structural divorce. By admitting most dual-ownership benefits currently fall within the rules, he frames the debate around enforcement rather than existence. For regulators, the harder question may be whether stricter sporting boundaries can actually prevent the cozy synergies that Brown fears have already compromised the spirit of the regulations.
