The
ARX-02a's radiators are located in the side pods towards the end of the
monocoque. Air is directed through the front suspension
shrouds
and into the side pods.
The
monocoque is raised more so than on the ARX-01a and is further
optimized for aerodynamic efficiency. This provides room for
a
more aggressive front diffuser. This would help gain back
most,
if not all and then some, of what was lost through the interaction of
the front tires and the diffuser.It can be argued that the ARX-02a has adopted an F1-style "zero keel" suspension mounting architecture.
The nose/splitter assembly locates onto the raised "chocolate finger" detail on the flange for the brake duct.
The
diffuser's trailing edge is notched . Best guess is
that these notches help energize the diffuser's trailing
edge flow.
Some elements
from the ARX-01a/b carry over. Here we can see the serrated
diffuser turning vanes.Acura ARX-01b |
The Acura ARX-02a's front diffuser cross section is a non-symmetric
wing profile that skirts Art 3.6.1 by coming to a blunt trailing edge.
We're to understand that the thickness of the trailing edge
is
around 30 mm, that being the undocumented dimension the ACO agreed upon
to then categorize the cross section as a "non-wing".
