Aston Martin has explained the design choices behind the AMR25, the 2025 Formula 1 car that it hopes will be “more driveable and benign” than its predecessor.
The Silverstone-based squad was unable to build on a promising base in 2024 as it regressed towards the midfield rather than closing the gap to the front runners ahead.
Aston Martin’s problems were once again rooted in mid-season upgrades not delivering the anticipated step on the track, culminating in a troubling end to the season.
Along with blunting its competitiveness, Aston Martin’s revisions to the AMR24 also triggered negative handling characteristics, causing an increase in crashes on the track.
Aston Martin CEO and Team Principal Andy Cowell has revealed that resolving that problem was an integral aspect that it paid attention to with the AMR25 over the winter.
“I’m excited to get this season started and see the AMR25 hit the track tomorrow in Bahrain,” Cowell, who arrived at the British marque in 2025, expressed.
“It’s the culmination of tremendous hard work and dedication at the AMR Technology Campus.
“We are all inspired by the DNA of Aston Martin and we have a relentless pursuit of excellence, both on and off the track.
“For this year’s car we’ve really taken on board the lessons and feedback from last season.
“We’ve focused on creating a more driveable car for Lance and Fernando and we’ve pushed hard to make it more benign.
“We expect it to be a tight and competitive field from the get-go in Australia, so we know it won’t be easy.
“Our aims are realistic with a view to how we can continually improve in all areas, especially as we, like all teams, approach a vital shake-up of the regulations in 2026.”
Speaking to media including Motorsport Week at the F1 75 season launch event, Cowell disclosed that the AMR25 would be “close to 100 per cent new” in components.
Aston Martin details 2025 car changes
Aston Martin has since expanded on the areas that have been changed as it bids to achieve those development aims and arrest the decline it has sustained in recent times.
The front wing marks a “significant evolution” upon the one that ended the previous campaign on the AMR24, honed towards “improving low-speed downforce”.
This should increase the car’s balance and make it more stable through all the corner phases, thus reducing the chances that the drivers will experience an unexpected snap.
This will be combined with rework to the rear wing on the AMR25 to minimise sliding, which should aid a smoother corner turn-in.
But the biggest departure comes with the sidepods, which now comprise a much deeper undercut compared to the AMR24 with a “swooping channel to guide airflow”.
To accommodate the revised sidepod design, Aston Martin has repackaged the radiator configuration on the AMR25 to ensure sufficient cooling to the powertrain.
Meanwhile, the engine cover contains a “razor-sharp spine” located between the airbox and the rear wing in order to control the airflow through to the back of the car.
That has been the controlling element with the floor design on the AMR25, with that part intended to work in conjunction with the sidepod and bodywork to improve the airflow under the car and over the rear wing.
The AMR25 will use a push-rod suspension convention at the front and rear, the same assortment that was used to mirror the move that supplier Mercedes made in 2024.
As Cowell alluded to, both Alonso and Stroll will sample the AMR25 in a shakedown at Bahrain on Monday prior to pre-season testing at the same venue later that week.
