But there was a lot more to the upgrade than initially met the eye, especially as the team was fairly coy when it came to detailing the changes it had made in the official car presentation submission document before the action got underway.
This is usual fare to be honest though, as all of the teams have, over time, become more accustomed to generalising the changes being made to their cars at each grand prix.
After giving some in-depth analysis of its changes when this new era of F1 began, most now take more of a catch-all approach to explain what has been altered in the various legality zones/boxes, with the vagaries of the actual changes still needing to be explored.
The prime example in Aston Martin's case is the changes made to its sidepods, which aren't mentioned in its submission documents at all but have obviously been overhauled as part of the package of alterations made to the AMR23.
However, that may be because unlike rivals Mercedes and Ferrari, which recently had to switch concepts, Aston Martin's changes were more about optimising the pre-existing surfaces to elevate performance.
The most obvious change in this respect was to the water slide-style gulley, which has been narrowed and starts a little further back, resulting in a steeper decline into the ramp section of the bodywork.
This also changes the shoulder profile of the bodywork and has led to the rear ramped section being altered where it meets with the floor.
