Widely recognized as one of the most technical and fascinating circuits on the Formula 1 calendar, Suzuka now also emerges as a crucial test for energy management. Mercedes arrives with confidence, ready to capitalize on a significant technical advantage before the April break offers rivals a chance to close the gap. Ferrari, on the other hand, is aiming to exploit the chassis strengths of the SF-26, although the limitations on active aerodynamics could turn those strengths into a potential weakness.
The strength of Mercedes
Heading into the Japanese Grand Prix, Mercedes stands out as the clear favorite. In Shanghai, the Brackley-based team demonstrated that it currently possesses the most complete package on the grid, and Suzuka is expected to highlight those strengths even further. The Japanese circuit plays perfectly to the Silver Arrows’ advantages, particularly their superior top-end speed and highly efficient battery management, partly enabled by the strong output of the internal combustion engine.
Suzuka is also one of the most demanding tracks when it comes to energy strategy, especially following the FIA’s decision to restrict the use of movable aerodynamic devices to only the main straight and the run leading into 130R for safety reasons. This limitation increases the importance of energy deployment and recovery, areas where Mercedes has consistently excelled.
The main threat to Mercedes could come from reliability concerns. In China, a technical issue disrupted George Russell’s Q3 session, while both McLaren cars failed to start the race due to a problem originating within the Brixworth power unit system. However, it would not be a major concern if Ferrari were to take the lead at the start once again. The long sequence of corners in the opening sector makes it difficult to respond to overtakes completed on the main straight, while significant clipping expected at Spoon Curve and 130R could encourage position changes.
Within the Mercedes garage, George Russell holds a slight advantage over Kimi Antonelli. The young Italian himself has acknowledged that his teammate still has the upper hand, particularly in energy management, an area where Russell appears more naturally comfortable. Nevertheless, Antonelli’s maiden victory in China has boosted his confidence, and Suzuka could offer him an opportunity to showcase his sensitivity in tire management.
Ferrari’s double-edged weapon
Ferrari approaches Suzuka with a slight deficit compared to Mercedes, especially on a circuit that does not fully reward the superior traction characteristics of the Italian power unit and its smaller turbocharger. However, the SF-26 demonstrated in China that it holds an advantage in high-speed corners, where aerodynamic load becomes critical. This could prove valuable at Suzuka, which features numerous fast sections such as the iconic Esses in sector one, the Degner curves, and Spoon Curve.
The car’s chassis qualities are also expected to play a key role in tire management during the race. Pirelli has selected the hardest compounds in its range—C1, C2, and C3—and graining on the front axle is once again anticipated. The severity of this phenomenon will depend on how the relatively new asphalt, introduced ahead of last year’s race, evolves, as well as on track temperatures, which will dictate the level of thermal degradation.
Despite Ferrari’s apparent advantage in aerodynamic load, it remains uncertain how beneficial this will be in practice. Energy management will be the dominant factor, forcing teams to divert part of the internal combustion engine’s power to recharge the battery. As a result, it will be crucial to understand in which corners the cars can actually operate at the limit of grip.
Moreover, increased downforce often comes at the cost of higher drag on the straights, which can negatively impact energy efficiency—particularly with active aerodynamics restricted to just two zones. Ferrari’s aerodynamic strength could therefore turn into a double-edged sword, unless the SF-26 proves capable of maintaining strong efficiency even with closed wings. On that topic, the Scuderia is expected to reintroduce its inverted rear wing—nicknamed the “Macarena”—in Japan, with three free practice sessions available to fine-tune its behavior, especially during the closing phase.
Hopes for McLaren and Red Bull
The most important upgrade for all teams, however, may simply be time. Following the Chinese Grand Prix, teams have had two weeks to analyze the data collected during the opening double-header, working to better understand how to extract maximum performance from their cars through setup adjustments and improved energy management strategies. Unlike Shanghai, Suzuka offers three full practice sessions, providing valuable track time to refine preparations.
Attention will therefore also be focused on McLaren. Although the Woking-based team did not start the race in China, it identified encouraging progress in power unit utilization, moving closer to Mercedes in that area. However, McLaren still suffers from an aerodynamic deficit compared to the Silver Arrows, which could prove decisive at a track like Suzuka.
Red Bull is also working intensively to improve the cornering behavior of the RB22, which Max Verstappen described as “undriveable” in Shanghai, attributing only a small portion of the issue to the power unit. Suzuka is also one of the circuits where lap time is particularly sensitive to car weight, penalizing teams that are further away from the regulatory minimum.
A final factor to watch
Finally, there is another crucial aspect to consider. The restrictions on movable aerodynamic devices will cause the cars to remain pressed close to the ground for extended periods under maximum downforce, accelerating wear on the floor. The risk is exceeding the 2 mm limit allowed by the regulations, which could result in disqualification. This scenario forces teams to adopt the right countermeasures early on.
Every team will be aiming to maximize its points haul ahead of the long April break, after which development updates could significantly reshape the competitive order seen so far this season.
