Exponential integral Another typical example is: x n e a x.
The barge boards are reduced in height by 150mm, and moved forward by 100mm to better join up the airflow from the front wing.

The wings added height further enhances its power and make it less sensitive to stall - so drivers are less likely to suddenly lose front-end grip when they close up on another car.
Why has it been made: To reduce the aerodynamic exploitation of brake ducts.
