Ferrari's ADUO 2 Engine Upgrade Not a "Game Changer" for Haas, Says Bearman
Oliver Bearman, the talented driver for Haas F1, has indicated that the most recent engine enhancement from Ferrari, known as ADUO 2, delivered only a minor performance boost when contrasted with the substantial advancements seen in Haas's chassis modifications. Even with this new power unit and achieving his strongest qualifying position since March at the Italian Grand Prix, Bearman's team unfortunately failed to score any points, prolonging their dry spell.
Ferrari's ADUO 2 Upgrade Offers Limited Impact for Haas in Italian Grand Prix
At the Italian Grand Prix, held on September 8, 2026, Ferrari introduced its second and final power unit upgrade for the season, designated as ADUO 2. This upgrade, part of the Additional Development and Upgrade Opportunities system, was specifically installed in Oliver Bearman's Haas F1 car. Despite this new component, Bearman, who is 21 years old, noted that the engine's impact was considerably less significant than the team's chassis upgrades.
Bearman achieved his best qualifying position since the Chinese Grand Prix in March, securing 12th place. However, the race at Monza proved challenging. Although he briefly held eighth position in the initial laps, he gradually fell back, unable to maintain pace with the Alpine and Racing Bulls teams. Ultimately, he finished 15th after a virtual safety car period, marking the seventh consecutive race without points for Haas, a streak as long as their lowest point in 2021.
Fred Vasseur, Ferrari's team principal, had already tempered expectations by stating that the ADUO 2 power unit was not expected to be a revolutionary upgrade. Bearman echoed this sentiment following the qualifying sessions. He elaborated that while more power is always welcome, the improvement was not enough to significantly alter their competitive standing, particularly on tracks less suited to high power output like Zandvoort. He emphasized that the aerodynamic upgrades had delivered a much more substantial performance gain, attributing this success to the diligent work of the Haas team.
The aerodynamic package introduced by Haas for Monza included a redesigned floor and revised bodywork around the sidepods and engine cover. While Bearman benefited from the new engine, his teammate, Esteban Ocon, utilized the new aerodynamic parts but did not receive the engine upgrade. Ocon was seven-tenths slower than Bearman in Q2 and attributed this disparity to the VF-26 car's inconsistent aerodynamics, an issue he claims has affected him in 10 out of 13 Grand Prix races this year. He expressed satisfaction with his own lap performance, despite the car's limitations, stating it was the maximum he could achieve given the deficit in downforce and engine performance. Despite the improvements, both Haas cars finished behind the Audi F1 Team, who are now only five points adrift in the constructors' championship.
This Grand Prix weekend highlights the intricate balance between engine and aerodynamic development in Formula 1. While every component upgrade is crucial, some, like Haas's recent chassis improvements, can yield far more significant competitive advantages than engine revisions. It underscores the continuous pursuit of marginal gains in F1 and the often-overlooked role of a well-balanced chassis in overall performance, even when supported by a powerful engine supplier.
