George Russell believes Ferrari could have a significant advantage at the 2026 Mexico City Grand Prix, identifying the team’s unusually small turbocharger as a potential strength at the high-altitude Autódromo Hermanos Rodríguez. The Mercedes driver has named the Scuderia among the favourites for the weekend, suggesting that a difference in power-unit design could help the SF-26 against its Formula 1 rivals.
Ferrari has attracted considerable attention ahead of the Mexican Grand Prix, with expectations growing that its engine characteristics could suit the unusual conditions. However, the potential benefit remains uncertain, and Haas driver Oliver Bearman, whose car uses a Ferrari power unit, has cautioned that the actual impact of altitude will only become clear once the cars are on track.
Why George Russell believes Ferrari could have a turbo advantage in Mexico
During the drivers’ press conference ahead of the Mexico City Grand Prix, George Russell identified Ferrari as his favourite to perform strongly at the Autódromo Hermanos Rodríguez. His assessment centred on one particular aspect of the Italian manufacturer’s power unit: the dimensions of its turbocharger.
The Mercedes driver explained that turbocharger performance is an important factor for every team at this circuit. He highlighted that Ferrari uses a very small turbo compared with other manufacturers and suggested that this difference could provide a worthwhile advantage in Mexico.
However, Russell also acknowledged that the demands involved in managing the system remain uncertain. Although he considers the Ferrari design a potentially beneficial difference, he did not suggest that the advantage was guaranteed or that the team’s performance could already be predicted with confidence.
The assessment adds another dimension to Ferrari’s preparations for the weekend, particularly as the Scuderia continues to evaluate the competitiveness of its SF-26 against Mercedes and the other leading teams. The different power-unit characteristics could become especially relevant under the unusual atmospheric conditions encountered in Mexico City.
Mexico City’s altitude makes turbocharger performance crucial
The Autódromo Hermanos Rodríguez is situated approximately 2,200 metres above sea level, creating one of the most demanding environments for Formula 1 power units. At this altitude, the air is considerably thinner and contains less oxygen per unit of volume than at circuits closer to sea level.
Those conditions place additional demands on the turbocharger, which must operate at higher rotational speeds to supply the engine with sufficient compressed air and help maintain its performance.
Turbocharger dimensions therefore become an important technical consideration. In general, a larger turbocharger can move a greater volume of air, offering potential benefits when the engine requires substantial airflow. A smaller design, meanwhile, typically responds more rapidly to changes in throttle demand.
That faster response can be valuable when a driver accelerates out of a corner. However, a smaller turbocharger may reach its operating limits sooner, potentially restricting peak power and introducing additional reliability considerations.
The challenge is consequently not as straightforward as identifying which manufacturer has the largest or smallest turbocharger. The effectiveness of each design depends on how successfully it combines airflow capacity, response, efficiency and reliability under the circuit’s demanding conditions.
Mexico’s altitude also creates wider technical challenges for the SF-26, with Ferrari facing particular cooling and grip concerns at the 2026 Mexico Grand Prix. Managing those requirements will form another important part of the team’s weekend preparations.
How the 2026 F1 power-unit regulations change the turbo challenge
Formula 1’s 2026 power-unit regulations have introduced another significant factor into the equation. The latest generation of engines no longer features the MGU-H, the electrical system that previously helped regulate turbocharger speed and reduce turbo lag.
Its removal changes the operating demands placed on the turbocharger, increasing the importance of finding an effective compromise between compressor efficiency and throttle response.
A turbocharger capable of moving substantial quantities of air may offer benefits at high altitude, but those characteristics must be balanced against how quickly the system responds when the driver demands acceleration.
Reliability also remains essential. Running a turbocharger under demanding conditions requires careful management, particularly when its operating requirements differ significantly from those encountered at lower-altitude circuits.
For that reason, the largest turbocharger will not necessarily provide the greatest competitive advantage in Mexico. The most effective solution could instead be the design that achieves the best overall balance between performance, response and durability.
This is the central uncertainty surrounding George Russell’s assessment. Ferrari’s smaller turbocharger could offer a useful characteristic, but the benefits will depend on how the complete power unit operates throughout a lap at the Autódromo Hermanos Rodríguez.
Oliver Bearman cautious about Ferrari engine expectations
Despite the optimism surrounding Ferrari’s potential performance, Oliver Bearman has urged caution ahead of the first practice sessions. The Haas driver also uses a Ferrari power unit, making the behaviour of the Italian manufacturer’s engine particularly relevant to his own weekend.
Bearman acknowledged that he did not yet know how Mexico City’s altitude would affect the power unit. Rather than making predictions about its competitiveness, he explained that running the car on track would be necessary to understand the conditions properly.
The British driver nevertheless expressed hope that the characteristics of the Ferrari engine could place Haas in a favourable position.
His assessment highlights the difference between the potential advantage identified by George Russell and the actual performance that Ferrari-powered cars will deliver at the circuit. Until the opening sessions provide comparable running, the impact of the different turbocharger designs remains an important unknown.
Can Ferrari turn its predicted Mexico advantage into performance?
Ferrari enters the Mexican Grand Prix with growing expectations surrounding the technical characteristics of its power unit. While the team’s relatively small turbocharger has attracted particular attention, its potential benefit must be considered alongside the wider demands of the SF-26.
The Scuderia is also seeking to build on the progress made at the United States Grand Prix, although Ferrari’s Austin upgrades face a different aerodynamic challenge in Mexico. The combination of altitude, engine characteristics and circuit layout will determine whether the Italian team can translate its encouraging recent performance into another competitive weekend.
For George Russell, the turbocharger represents a reason to regard Ferrari as a serious contender. For Oliver Bearman, the question remains open until the cars begin running under Mexico City’s unusual conditions.
The first indications are expected during Friday’s two practice sessions, scheduled to begin at 19:30 and 23:00 respectively. These sessions should provide an early opportunity to assess how the different power units respond to altitude and whether Ferrari’s design offers the advantage anticipated by its Mercedes rival.
Fans can follow the complete 2026 Mexico City Grand Prix schedule for the weekend’s practice, qualifying and race timetable.
The opening running will therefore be particularly revealing for Ferrari. The SF-26 has been identified as a potential favourite before a competitive lap has been completed, but the decisive question is whether its distinctive turbocharger characteristics can deliver a measurable benefit against Mercedes and the rest of the field.
