The AMR23 is clearly inspired by the Red Bull in terms of aerodynamics, but underneath there is Mercedes technology and that can stand in the way of further development, writes Formu1a.uno
Aston Martin is doing well in 2023, the formation from Silverstone has taken a big step forward. Although Aston Martin is a customer team of Mercedes and reportedly borrows the entire rear of the W14, their car looks very similar to the Red Bull on the outside.
But it is mainly the rear of the Mercedes that can hinder the further development of the AMR23.
The gearbox and suspension are the same as the Mercedes. Those parts are larger and heavier and cause a poorer airflow in the diffuser of the AMR23. Those parts are designed for a car with a very compact body, such as the W14 with the zero sidepod concept.
The combination of the aerodynamic concept of Red Bull and the mechanical part of Mercedes therefore counteracts each other in the car of Aston Martin. The problems with the airflow in the diffuser can be partly solved by adjusting the rear wing, but that would in turn increase drag, which would be detrimental to the speed on the straights.
