Gearbox concerns cast a shadow over Aston Martin’s Monaco weekend
While Honda believes Monaco could represent its best opportunity so far this season to finally score points, Fernando Alonso appears far less optimistic as the Formula 1 paddock settles into the iconic Monaco Grand Prix weekend.
The unique nature of the Monte Carlo circuit could work in Aston Martin’s favor. Monaco places far less emphasis on outright power unit performance than most tracks on the calendar, with aerodynamic efficiency, mechanical grip and driver confidence playing a much bigger role. However, despite the potentially favorable conditions, concerns remain within the Silverstone-based team.
The biggest worry stems from the gearbox issues that first emerged during the Miami Grand Prix weekend. According to both Fernando Alonso and Lance Stroll, the problem involved the transmission occasionally selecting gears unpredictably in certain situations, creating potentially dangerous handling characteristics.
To race or not to race?
“Monaco is not the right circuit for random gear changes, which can cause rear brake locking and/or engine slipping. In that situation, the risk of ending up in the wall is extremely high and we could end up looking foolish. Sometimes it feels like you’re simply a passenger in the car: you downshift and the engine suddenly gives you a surge of power as if you were at full throttle,” Fernando Alonso explained.
The issue reportedly occurs in two distinct scenarios, both linked to situations where the power unit is operating at relatively low speeds. It can happen under acceleration when there is a torque delivery deficit compared to the expected value, or during downshifts where perfect synchronization is required to prevent instability at the rear of the car.
Such behavior is particularly concerning around Monaco, where precision is everything. The narrow barriers leave no room for error, and even the smallest unexpected movement from the car can have serious consequences.
“If the downshifting problem we experienced in Miami happens again, we might not even be able to race, because we would end up in the wall at one of the braking zones,” Fernando Alonso added.
As has often been the case throughout his Formula 1 career, the two-time world champion may have exaggerated slightly to underline the seriousness of the issue. Nevertheless, his comments highlight the level of concern surrounding a problem that could become particularly dangerous on the streets of Monte Carlo.
A nearly exposed engine
Beyond the gearbox concerns, Aston Martin is still dealing with overheating and reliability challenges related to the Honda power unit.
The problems have not been completely eliminated, forcing the team to continue adopting aggressive cooling solutions. Even at Monaco, where ambient temperatures are not expected to be especially high, Aston Martin has significantly opened up the bodywork around the engine.
Large cooling louvres and ventilation grilles are visible on both sides of the engine cover, exposing far more of the Honda power unit than is typical in modern Formula 1. The design is intended to maximize airflow through the car and help control operating temperatures during the demanding race weekend.
What makes the solution particularly striking is that weather forecasts are relatively mild, with maximum temperatures expected to reach only around 24°C. Compared to the cooling configurations used by rival teams, Aston Martin’s setup stands out immediately.
The extensive openings serve as a reminder that, despite progress made throughout the season, reliability remains a key area of focus for the team. While Monaco could offer Aston Martin an opportunity to be more competitive due to the circuit’s characteristics, both gearbox reliability and power unit cooling continue to raise questions ahead of one of the most challenging races on the Formula 1 calendar.
