As Aston Martin bids to retain fourth place in the constructors’ standings against the major in-season gains made by McLaren, the AMR23 has been given an updated floor, bodywork and beam wing.
For Austin, the floor edge has been tweaked and a longitudinal slot plus outboard wing added, the wing having previously been mounted under the floor. The diffuser gains a revised side view expansion.
The engine cover bodywork has been modified with a large undercut alongside the revised floor edge, while a new beam wing with revised profiles and incidence will interact with the reshaped diffuser.
This four-part update has been conceived to work as one to increase the performance of the underside of the floor.
Since the US GP runs as a sprint race, there is only one practice session to validate the changes.
Aston Martin has already explained that the progress made towards its 2024 car has influenced the final tweaks made to this year’s challenger.
Fernando Alonso said: “Even if you stop someone now in the paddock and ask, ‘Which one had a better season until now, Aston Martin or McLaren?’ 99% of the people will say McLaren.
