Formula 1 faces a potential "dangerous path" as teams may attempt to manipulate the FIA’s Additional Development and Upgrade Opportunities (ADUO) system. Designed to allow power unit manufacturers trailing the benchmark to introduce performance-boosting upgrades, the mechanism is currently under scrutiny as the sport navigates the complexities of new engine regulations.
With Mercedes HPP currently setting the standard—having secured victories in all three Grands Prix, the China Sprint, and front-row lockouts in every qualifying session—the benchmark for the ADUO calculations is clear. Following the Miami Grand Prix, manufacturers within 2% of Mercedes HPP will be granted one additional upgrade for 2026 and 2027, while those trailing by 4% will be permitted two upgrades per year across this season and next.
Former F1 driver and World Endurance Champion Anthony Davidson has voiced significant concerns regarding the potential for teams to intentionally mask their true performance. Speaking on the Sky Sports F1 podcast, Davidson warned that teams might "sandbag" to artificially qualify for these upgrade opportunities.
“What we really don't want this to turn into is balance of performance,” Davidson stated. “I don't think it really has a place in Formula 1, and it should be about who are the best engineers, who can use their money the most wisely and, in effect, the cost cap is F1 balance of performance.”
Davidson emphasized that the current technical landscape, which heavily integrates complex electrical systems alongside the internal combustion engine, makes performance evaluation particularly difficult. “You could end up going down a dangerous path here, with teams jumping up saying: 'We need a bit of a performance gain here', and they might be sandbagging to get that performance gain,” he added.
Mercedes team principal Toto Wolff has also weighed in, stressing that the ADUO system should not function as a "leapfrog" mechanism. The intent is not to allow struggling manufacturers to surpass those who have demonstrated superior engineering prowess in the development of the new power units.
Davidson echoed this sentiment, arguing that the sport must be handled with extreme caution to avoid the pitfalls seen in other racing categories that utilize formal balance of performance measures. “It has to be handled extremely carefully; otherwise, you do get into a situation that we see in many other categories around the world where they do have a balance of performance and games are played,” he concluded.
As the season progresses, the challenge for the FIA will be to ensure that the pursuit of a level playing field does not inadvertently incentivize teams to compromise the integrity of the competition.
