Remove ads
The Aston Martin AMR25 is a Formula One racing car designed and developed by the Aston Martin Aramco F1 Team competing in the 2025 Formula One World Championship.[1] It is the fifth Formula One car entered by Aston Martin since rejoining the sport in 2021, and is being driven by two-time world champion Fernando Alonso and teammate Lance Stroll. Reserve driver duties will be handled by Felipe Drugovich and Stoffel Vandoorne.

Livery
All ten teams, including Aston Martin, unveiled their livery on 18 February 2025 at a dedicated event.[2]
At the Chinese Grand Prix, the team paid tribute to Eddie Jordan (the founder of Jordan Grand Prix, the team's ancestor), who died right before the race weekend. His name and team logo with a red leaf that represents heart were present on the side of the car and a side of the rear wing.
Development
The AMR25 differentiates itself from the AMR24 with a new front wing, new side pods, and a detached upper wing plane.[3] The new sidepod and bodywork design complement this, allowing better management of airflow under the car and over the rear wing. The AMR25 has push-rod suspension at both the front and rear; the suspension is connected to the chassis by a diagonal structure with a higher point on the car's bodywork. The floor design has been revised to improve airflow under the car. The AMR25 will be the last Aston Martin car to utilise Mercedes power units, as the team signed a deal with Honda[4] to utilise their engines from the 2026 season.[5]
Technical Specifications and Design;
- Engine: Mercedes-AMG F1 M15 E Performance V6 turbo hybrid power unit. It has a 1.6-litre displacement and, combined with two hybrid electric motors, produces approximately 1,080 horsepower, with a rev limit of up to 15,000 rpm.[6]
- Transmission: Mercedes F1 eight-speed, semi-automatic, sequential gearbox.[7]
- Weight: Minimum weight of 798 kg including the driver, in accordance with FIA regulations.
- Dimensions: 5.60 m in length, 2.00 m in width, 0.95 m in height; with a wheelbase of 3.60 m.[8]
- Suspension: Push-rod type suspension on both front and rear. The front suspension was revised to work in conjunction with the front wing and floor, while the rear suspension was optimized to improve airflow management at the rear inlet.[9]
- Aerodynamics: The design of the front wing and nose was modified. New winglets on the front wing better manage airflow turbulence caused by the front wheels, enhancing aerodynamic efficiency. The sidepods and bodywork were completely updated to improve airflow towards the floor and rear wing.[7]
- Chassis: Carbon fibre composite monocoque structure aimed at lightness and durability, reinforced with new anti-penetration panels for enhanced safety.[9]
Performance and On-Track Status;
- Balance Issues: With the AMR24, the team experienced inconsistencies in low-speed corners and various sections of circuits compared to previous years. Both Fernando Alonso and Lance Stroll frequently complained about the car’s inconsistent balance between tracks and even between laps.[10]
- Strengths: The car exhibited strong downforce at low speeds; however, this high aerodynamic load also contributed to balance problems. While improvements were noted in straight-line speed with DRS activated and in high-speed corners, overall performance lagged behind competitors.
- Improved Cooling: Optimization of the bodywork and sidepods enhanced airflow under the floor and improved brake cooling.
- In-Season Development: New front wing and floor modifications introduced during the 2025 season aimed to deliver greater stability in mid-corner and corner exit phases. However, some tests did not yield the desired results, leading the team to occasionally revert to older components.[11]
- Results: The team showed less development than rivals, particularly in the first half of the season, resulting in a widening performance gap. Their points tally in the early part of the 2025 season did not meet expectations.[12]
Despite featuring a range of technical updates—including weight reduction, new aerodynamic components, and modern safety panels—the Aston Martin AMR24 struggled to meet expectations in 2025 in terms of both balance and development pace on track. The technical team and drivers continued to focus particularly on improving low-speed corner performance and overall vehicle stability. Building on lessons learned from the AMR24, the team is working on more comprehensive solutions for the 2025 and 2026 seasons.[13]
Recent Developments on the AMR24: The latest upgrades primarily targeted the chassis, aerodynamic components, and suspension system, directly impacting specific performance aspects on track. Key focus areas highlighted by Technical Director Dan Fallows and the team engineers include:
- Aerodynamic Efficiency: Complete redesign of the front wing, nose, floor, and sidepods improved management of airflow behind the front tires and ensured more controlled delivery of air around the body to the floor and rear wing. These changes aim to increase downforce in high-speed corners, enhancing grip.
- Floor Revision: The floor is the section of an F1 car that generates the most downforce. The updated floor design on the AMR24 increased downforce and aimed to improve the overall balance of the car.
- Suspension Systems: Modifications to both front and rear suspension involved an overhaul of the push-rod system and improved integration with the chassis. These revisions were made to enhance mechanical grip across different circuit sections while maintaining compliance with regulations regarding flexibility.
- Wider Operating Window: The upgrades aim to enable the car to perform optimally across a broader range of ride heights and setups, supporting more consistent performance on various track types and corner profiles.
- Power Unit and Integration: Optimizations related to the Mercedes power unit and gearbox necessitated redesigning the rear suspension geometry, enhancing the integration between engine and chassis.[14]
- Weight and Durability: The carbon fibre monocoque chassis, reinforced with new anti-penetration panels, provides a lighter yet stronger structure, contributing positively to driving dynamics and driver safety.[14]
The innovations in these areas aimed to enhance the car’s overall speed and balance capabilities, while providing a more predictable and consistent driving experience on track. However, team and driver feedback has confirmed that the changes, alongside updates applied throughout the season, did not always deliver the expected improvements and occasionally complicated the car’s handling characteristics.[14]
