F1 to debate Vowles’ cost-cap catch-up proposal

Formula 1 is set to debate a proposed cost-cap catch-up mechanism at its Monday commission meeting, with the plan dividing teams over whether struggling squads should be allowed to spend more.

The proposal, put forward by Williams team principal James Vowles, has been named “ADUO for teams”. It would introduce a sliding scale under which teams outside the top four could receive greater spending freedom, with the allowance increasing for those lower in the standings.

Vowles’ argument is that the cost cap has helped make teams financially viable but can also preserve advantages built up by frontrunners, making it harder for smaller operations to close the gap. The debate is relevant to his wider work at Williams, including his long-term championship ambition and the team’s planned aerodynamic changes.

Support for the proposal remains short of a supermajority

The name mirrors the existing engine-maker scheme, which grants additional spending, dyno time and homologation opportunities to manufacturers whose power units trail the benchmark.

To pass into the rules as early as next year, Vowles’ plan would need backing from the FIA, Formula 1’s commercial rights holder and six of the 11 teams. So far, Cadillac, Alpine, Aston Martin and Audi have indicated support. Haas opposes the idea because it is not close to the current cap and therefore is not constrained by it; Racing Bulls team principal Alan Permane has also rejected the concept.

A narrower route may still be possible: support from four teams in total could allow the proposal to be introduced for 2028. That would leave time for it to influence the regulation cycle due to begin in 2030 or 2031. Vowles has said he wants a solution that works for the sport, while cautioning that it will take time to agree on the right approach.

Staff pay is driving a separate cost-cap debate

The discussion is also expected to broaden beyond catch-up spending. Leading teams are concerned that salary limits make it harder to retain engineers, as staff can be attracted by better-paid roles in technology companies or other racing series. The cap’s inflation-linked increases have also limited teams’ ability to respond to rising living costs.

One proposal gaining traction is to treat spending on people separately from spending on parts. Toto Wolff said Mercedes had previously sought an allowance to improve pay for junior staff, arguing that the existing rules suppress salaries during their early years in the team. That proposal did not win support.

The current rules exempt only an organisation’s three highest-paid personnel. Past discussions of extending that exemption to as many as 300 staff were considered too broad and risked undermining the cap. The commission now faces two connected questions: how to give smaller teams room to catch up, and how to protect the talent pool without weakening spending controls.
