FER­RARI FLOOR

Autosport (UK) - - JAPANESE GP TECH - GARY ANDERSON

Fer­rari tested a new floor at Suzuka last Fri­day, but re­verted to the older ver­sion for Satur­day on­wards.

The older ver­sion (inset) has an L-shaped outer cor­ner slot gap. This al­lows the air that is dis­placed by the rear tyre ro­tat­ing onto the ground to pull on this slot, tak­ing air­flow from the top sur­face of the floor through the slot; and with it, scav­eng­ing air­flow out­wards that would nor­mally be pulled into the dif­fuser area, re­duc­ing the per­for­mance of the whole floor.

The new ver­sion with the two ar­rows ex­tends that L-shaped slot in­wards. With my lim­ited un­der­stand­ing of how Fer­rari’s anal­y­sis ex­pects this area to work, I have no idea why you would do this. It will al­low more air­flow to go in­side the rear tyre, which will re­duce the dif­fuser’s per­for­mance.

The only pos­i­tive that could come from this de­vel­op­ment is a po­ten­tial reduction in sen­si­tiv­ity to ride-height change. But this reduction will come from a loss at the high ride heights in­stead of a gain at low ride heights, which over­all will be a neg­a­tive.
