The
Eagle MkIII wasn't the first sports cars to utilize a front underbody aero
concept designed to develop downforce. Even the very first
GTP cars were looking in that area to generate localized low pressure to
improve front balance. But the MkIII was most definetly the first
to take that concept to the next step by intentionally exiting the airflow
from the front diffuser out the side of the car and fully providing for
as clear a path as possible, both into and exiting the diffuser, for the airflow. |
The
diffuser forms wings either side of a central "bubble", that is, a
surface undulation that blends back tangent to the floor but causes a local
pressure reduction. The diffuser wings then extend from the bubble
section to just with in the front wheel well and utilizes the spinning
action of the front wheels to further draw airflow though the bubble and
the diffuser. |
Here we can see the wings of the diffuser upsweep and their proximity to the wheel and suspension members. |
In
this shot the front splitter has been removed (hence the daylight in
the top portion of the image). Here you just begin to get an
idea of the clear path the airflow has out the car via the outlet aft
of
the front wheel. |
