Engine Disadvantage for Ocon at Italian GP: Haas Gets Only One Ferrari ADUO2 Upgrade

Haas F1 Team enters the Italian Grand Prix at Monza with a clear disadvantage: only one of its two drivers will receive the upgraded Ferrari ADUO2 engine. That driver is Oliver Bearman, the Ferrari Academy talent, while Esteban Ocon – the more experienced driver – must use the previous-spec unit. This decision not only affects internal balance but also exposes the power structure within Ferrari's customer team ecosystem. According to Motorsport.com, Ferrari supplied only one ADUO2 engine to Haas for Monza. Team principal Ayao Komatsu confirmed: “We will have a new aero package for both cars, but only Bearman gets the upgraded engine.” Ocon acknowledged the loss: “I don't have that engine, it's a loss. But I have the new aero package.” He tested the package on the simulator on Tuesday and felt it was “better,” but emphasized that Monza “is not the most technical circuit, so we won't see the full gain; more in Madrid.” The engine disparity at Monza – a high-speed circuit with long straights – could be worth several tenths per lap, enough to decide whether points are scored in a tight midfield. Haas is currently on a points drought since Monaco, and Ocon admitted that rivals like VCARB and Alpine have developed faster: “They started the year well in terms of pace, others developed faster, we were waiting for this package.” Regulatorily, the FIA sees no issue: the rule requiring “same specification” engines is deemed complied with if at least one upgraded engine is supplied to the customer team. This sets a precedent that could affect other customer teams in the future. Ocon expressed frustration with overall performance: “We had two very good weekends that turned out to be frustrating. I think I have maximised the potential of the car.” However, he did not criticize the team or teammate, focusing instead on the car's lack of pace. The new aero package is expected to address weaknesses in grip and cornering speed, but Monza is a low-downforce circuit, so the true effect will only be assessed at more technical tracks like Madrid, Barcelona, or Suzuka. If the package fails to deliver clear improvement, Haas risks being stuck in the lower midfield for the rest of the season. The priority given to Bearman is no coincidence. He is a Ferrari Academy product, and giving him the upgraded engine allows Ferrari to evaluate ADUO2 performance on a young driver while developing talent for the future. This reflects the reality that customer teams must accept asymmetry in resources from their engine suppliers. Strategically, Haas may adopt a split approach: Bearman with the stronger engine will attack more aggressively, while Ocon manages a more conservative race. However, no detailed pit-stop or tire strategy information was provided in the original article. Overall, the Italian GP is a critical test for Haas. If Bearman scores points with the upgraded engine and Ocon does not, the internal inequality story will gain more attention. But if both fail to score, the problem lies deeper in the team's development capability. For Vietnamese fans, this story highlights a harsh reality of F1: not only the driver matters, but the entire support system – from engine, aerodynamics to bargaining power – determines the final position. Haas is in a survival fight in the midfield, and Monza will be the first measure of their recovery ambitions.
