McLaren boss escalates Red Bull criticism over “unhealthy” F1 structure
Zak Brown has intensified his criticism of Red Bull Racing, branding the organisation’s dual-team model as “unhealthy” and calling for closer scrutiny of how closely aligned outfits operate within Formula 1.
The McLaren CEO has been one of the most vocal figures on the grid when it comes to governance and competitive integrity, and his latest remarks underline growing unease among rival teams about Red Bull’s relationship with sister squad Racing Bulls.
“Unhealthy” dynamic questioned
Brown’s central concern revolves around the level of collaboration possible between two teams that share ownership, infrastructure philosophies, and—critically—strategic alignment. While Formula 1 regulations prohibit direct sharing of certain intellectual property and mandate operational independence, Brown suggested the reality may be more nuanced.
According to him, the ability to exchange drivers, data trends, and development direction—whether formally or informally—creates a competitive asymmetry. In a cost-capped era designed to level the playing field, he implied that a two-team ecosystem could effectively double strategic bandwidth.
His comments are the latest in a series of critiques aimed at ensuring stricter enforcement of independence between teams with common ownership.
Red Bull’s long-standing model
Red Bull’s multi-team approach dates back to its entry into Formula 1 in 2005. Just a year later, the company acquired a second outfit, rebranding it as Toro Rosso for the 2006 season. Based in Faenza, the team has since evolved through multiple identities—AlphaTauri and VCARB—before becoming Racing Bulls in 2025.
Throughout its history, the junior team has functioned as both a proving ground and a strategic extension of the senior operation. It has played a pivotal role in identifying and nurturing talent, often accelerating drivers into race-winning machinery once they demonstrate readiness.
Among the most successful graduates are four-time world champion Sebastian Vettel and current dominant force Max Verstappen. Others, such as Daniel Ricciardo and emerging prospect Isack Hadjar, further illustrate the pipeline’s effectiveness.
Strategic advantages under scrutiny
Critics argue that the benefits of such a system extend beyond driver development. Having two cars in a secondary team can provide additional real-world data across race weekends, alternative setup experimentation, and broader strategic flexibility during grands prix.
Even within regulatory limits, the perception persists that affiliated teams may align on race strategy in ways that indirectly benefit the senior outfit—whether through track positioning, pit window timing, or defensive driving against rivals.
Brown stopped short of accusing Red Bull of rule-breaking, but his use of the term “unhealthy” signals a belief that the current framework may not adequately protect competitive fairness.
Regulatory grey areas
The FIA has repeatedly stated that all teams must operate independently despite shared ownership structures. However, enforcing that independence particularly in areas like aerodynamic philosophy, simulation tools, and personnel movement remains complex.
The introduction of the cost cap was intended to reduce financial disparities, but it has also heightened sensitivity around any model that could provide indirect efficiencies or shared learning curves.
Brown’s stance aligns with a broader push from some teams for clearer boundaries and potentially tighter restrictions on collaboration between sister outfits.
Red Bull’s likely response
Red Bull have consistently defended their structure, maintaining that both teams comply fully with FIA regulations and operate as separate entities. They argue that their junior team is essential for developing young drivers and sustaining a pipeline of talent into Formula 1.
From their perspective, the success of drivers like Verstappen and Vettel reflects strong talent identification rather than systemic advantage.
A debate far from over
As Formula 1 continues to evolve under cost cap constraints and closer performance margins, governance issues are becoming increasingly prominent. Brown’s latest remarks ensure that the spotlight remains firmly on multi-team ownership models.
With Racing Bulls continuing to play a strategic role in Red Bull’s ecosystem, and rivals growing more outspoken, the controversy is unlikely to dissipate anytime soon. Instead, it may prompt deeper regulatory review—and further political tension—within the paddock.
