 Compare
the diffuser section above (Sebring) with below (Sears Point). The
Sears Point diffuser is smaller than maximum width (100 cm). |
 Sears
Point diffuser section. Note that the diffuser's walls have moved
in towards the car centerline, the walls being in the same place as the
strakes in the Sebring diffuser. The Sears Point diffuser does not
have any strakes in the section. The narrowed diffuser is now less
effected by the negative interaction with the rear wheels therefore generating
actually more downforce even with reduced area. |
 The
bottom edge of the longtail sections is very sharp (yellow highlights).
A vortex sheds off the sharp edge producing downforce, creating what is,
in essence, an additional diffuser section. |
