Kimi Antonelli has suggested that one of Mercedes’ key Formula 1 rivals could soon receive regulatory assistance from the sport’s governing body, potentially reshaping the competitive order as the 2026 season unfolds.
The young Mercedes-AMG Petronas Formula One Team driver has enjoyed a sensational start to the campaign, claiming back-to-back victories in China and Japan. His performances have not only strengthened Mercedes’ grip at the top of the constructors’ standings but also intensified his intra-team battle with George Russell in the drivers’ championship.
Mercedes have swept all three grands prix contested so far this year, opening up a commanding 45-point advantage over nearest challengers Scuderia Ferrari. However, Antonelli has indicated that Ferrari may soon benefit from a regulatory mechanism introduced by the Fédération Internationale de l’Automobile (FIA) for the 2026 season.
The mechanism, known as Additional Development and Upgrade Opportunities (ADUO), was implemented as part of the new power unit regulations. Designed as a safety net for underperforming manufacturers, ADUO allows eligible teams to introduce performance upgrades to their internal combustion engine (ICE) at three designated points during the season — after races six, 12, and 18.
The first opportunity is scheduled to follow the prestigious Monaco Grand Prix. Should Ferrari meet the necessary performance criteria, they could gain a valuable chance to close the gap to Mercedes in the early stages of the championship.
Under Article 4 of Appendix 4 of the 2026 technical regulations, a manufacturer qualifies for these additional upgrade windows if its ICE Performance Index is at least two per cent, but less than four per cent, below that of the best-performing engine. This performance-based threshold ensures that the system supports competitiveness without unduly penalising leading manufacturers.
Antonelli’s remarks suggest that Ferrari may fall within that performance bracket, potentially unlocking their first ADUO window in June. If confirmed, such an allowance would offer the Maranello outfit a critical opportunity to refine its power unit and regain momentum in a season currently dominated by Mercedes.
While the Brackley-based team has set the early benchmark under the sport’s new regulations, the introduction of ADUO was always intended to prevent prolonged performance disparities. With the championship battle still in its infancy, any technical breakthrough by Ferrari could significantly alter the competitive landscape.
For now, Mercedes remain firmly in control — but with regulatory lifelines available to struggling rivals, the 2026 title fight may be far from settled.
