Following substantial technical upgrades introduced earlier this year at Imola, Aston Martin will bring a new floor and revised bodywork to the 2025 British Grand Prix at Silverstone, with the clear objective of improving aerodynamic airflow management around the rear tires of their AMR25 Formula 1 car. The team has confirmed that this will be the final significant evolutionary package of the season, as their focus now shifts entirely toward preparing for the 2026 championship.
Since Aston Martin rolled out a substantial upgrade package at the Emilia-Romagna Grand Prix in Imola, the AMR25 has demonstrated a clear performance leap forward, accompanied by increased driver confidence behind the wheel. The AMR25 was initially designed to be a more manageable car compared to its predecessor, the 2024 AMR24, which in the relentless pursuit of pure aerodynamic downforce had become extremely challenging to drive.
As a result, the base specification of the AMR25 was indeed easier to handle, but this came at the cost of partially sacrificing outright aerodynamic downforce. This trade-off contributed to the car making the least progress in the early rounds of the 2025 Formula 1 World Championship compared to its rivals. However, with the Imola upgrade package, Aston Martin regained lost downforce and pace, consistently placing itself in points-scoring positions, even if the overall championship standings have not yet fully reflected this improvement.
At Silverstone, Aston Martin plans to introduce further upgrades, specifically focusing on a new floor and revised bodywork aimed at optimizing the aerodynamic flows around the rear wheels. While the Imola package primarily focused on reshaping the sidepods (panniers), the update scheduled for debut at the British Grand Prix will concentrate mainly on the car’s floor.
Team Principal Andy Cowell confirmed these developments, emphasizing that this is realistically the final major upgrade for the 2025 season. He explained that the new floor and modified bodywork build upon the earlier Imola updates but with a different aerodynamic emphasis. “At Imola, the focus was mostly on the upper bodywork shape. This time, the attention is mainly on the floor, with a minor adjustment to the upper section intended to improve the quality of airflow around the rear tires,” Andy Cowell stated.
Cowell also indicated that Aston Martin has completed their last planned wind tunnel session with the AMR25. He noted that while the rapid turnaround now possible for testing could allow for further development, there are currently no additional tests scheduled. The state-of-the-art facilities at the Silverstone factory have accelerated development timelines compared to previous years.
The final year of a regulatory cycle is always a delicate phase, especially when teams face the strategic decision of when to stop investing in the current car and fully shift resources toward the development of the next season’s car. This decision varies from team to team, depending on factors such as present and future ambitions and their current standing in the championship.
Aston Martin has openly acknowledged that the 2025 season is pivotal — not necessarily for making a big leap forward in the dying days of this technical cycle, but rather for laying the groundwork for the future of Formula 1. The team is focused on finding the right balance between integrating new engineering talent and maximizing the potential of the new facilities where significant investments have been made.
The package introduced at Imola in May was developed and validated in Aston Martin’s new Silverstone wind tunnel. This represented a crucial step to ensure consistency between factory data and on-track performance following a long calibration phase.
Now the aim is to take the next step: confirming the effectiveness of the updates tested on track and developed in the state-of-the-art facilities, while also making the AMR25 more competitive in the midfield battle. In this zone of the championship standings, even tenths of a second can make a significant difference between finishing at the back of the grid and scoring valuable points.
